Low Speed High Torque Hydraulic Motors
MG Series Torqmotor™
Introduction:
The MG Series Torqmotor™ provides an economical hydraulic motor for light to medium duty applications such as
grain augers, spreaders and car wash brushes which require dependable service life. The MG Torqmotor™ is
available with industry standard porting, coupling shafts and mounting configurations. In addition, these versatile
motors are compatible with many hydraulic systems with regard to pressure, torque and speed requirements.
Features:
•
•
•
•
•
•
•
•
•
Roller vane rotor set design reduces internal friction and compensates for wear, extending the useful performance life
of the Torqmotor™.
Patented 60-40 spline member arrangement of the mating internal splines transmits more output torque with less
weight.
Full flow lubrication maximizes cooling and provides up to 50% longer life than hydraulic motors not having this
feature.
Balanced performance in both directions of rotation.
Shaft seal design withstands full system pressures eliminating the added cost of a case drain line.
Orbital phase shift commutation at 6 times shaft speed provides smooth operation at low shaft speeds.
Commutation is not affected by side loads, as are competitive spool valve designs, allowing the Torqmotor™ to
maintain volumetric efficiency over time.
More starting torque than competitive motors in applications where the shaft is side loaded. Competitive designs
require more pressure and flow to start the motor rotating.
Overall design is less sensitive to hydraulic system contamination than competitive hydraulic motors.

The allowable radial load curve
Allowable Radial Load Curve
(Chart A) for the MG series is
2000
based on uni-directional steady
state loads for 2.5 x 106 revolutions and B10 bearing life. For
different load-life relationships
1500
see Chart B. Use the multiplier
times the allowable radial load to
predict different bearing life. See

Allowable Radial Load Limits
section for load calculations.

- This curve is for the SAE A (2 Bolt) Mount, Standard Mount (4 Bolt) and 4 Bolt Mount housing
styles. For SAE A (2 Bolt) (Long Pilot) Mount, subtract .18" from the actual radial load center line
to the motor mount face distance; use this value to find the allowable radial load.
Cross Port Relief Endcover
Integrated design relieves high pressure to the low pressure side of the Torqmotor™. Relief option functions for both
ports. A variety of relief settings are available for your application needs. Note, relief setting not to exceed intermittent rating of the motor.
Option adds .87" to overall length of Torqmotor™ and 4.5 lbs weight.

MF Series Speed Sensor Option
The rugged, weather resistant design is ideal for industrial and mobile applications. Applications include salt/sand/fertilizer
spreader drives, conveyer drives and injection molder compression drives. The sensor is a hall-effect type, which when externally powered outputs 30 square wave digital pulses per coupling shaft revolution. The connector is a user friendly universally
available 4 pin polarized M12 connector allowing for simplified field service. The integrated design does not effect the side load
capacity or performance of the Torqmotor™.

MP Series Torqmotor™
Introduction:
The MP Series Torqmotor™ provides reliable, efficient performance and long-term economy in a broad range of
applications, such as conveyors, irrigation equipment, scissor lifts and turf equipment. This hydraulic motor is ideal
for moderate torque applications, high side load capabilities where dependability and low speed performance is a
must. Case drain not required.

Compact size.
Combines proven performance of Ross Small Frame motors with side load capabilities of more expensive competitive
motors.
Roller vane rotor set design reduces internal friction and compensates for wear, extending the useful performance life of the
Torqmotor™.
Patented 60-40 spline member arrangement of the mating internal splines transmits more output torque with less weight.
Full flow lubrication maximizes cooling and provides up to 50% longer life than hydraulic motors not having this feature.
Commutation is not affected by side loads, as are competitive spool valve designs, allowing the Torqmotor™ to maintain volumetric
efficiency over time.
More starting torque than competitive motors in applications where the shaft is side loaded. Competitive designs require more
pressure and flow to start the motor rotating.
Overall design is less sensitive to hydraulic system contamination
than competitive hydraulic motors.
Industry standard ports and mounting.

MB Series Clutch
The MB Series clutchmotor consists of an MB motor with its internal
shaft separated from its output shaft by a set of springs. Both shafts
contain face teeth which are held apart by the springs. The output
shaft rides in a set of roller bearings. When pressure is applied to the
motor ports causing the motor to rotate, the internal shaft moves
forward, compressing the springs, and engaging the two sets of teeth.
The motor will not function as a standard motor. When hydraulic
pressure is lost to the motor ports, the springs separate the two sets of
teeth. The motor then ceases to rotate and the output shaft is free to
rotate in its bearings. This will happen whether pressure is lost at the
motor ports by design or inadvertently. The possibility of inadvertent
loss of pressure at the ports causing a freewheeling shaft condition
should be considered in the application of the clutchmotor.

Hot Oil Shuttle Endcover
A Hot Oil Shuttle is used to continuously remove a portion of the fluid in a closed loop transmission or other closed
loop system. At 125 PSI pressure differential between the motor return port and the shuttle outlet, 1.5 GPM* will
exit the circuit to cool, filter and return to the reservoir. The constant loop replenishment helps to keep heat and
contamination from building up in the circuit.

Allowable MB Series Side Load Limits
The allowable radial load curve (Chart A) for the MB series is based on uni-directional steady state loads for 3 x 106
revolutions and B10 bearing life. For different load-life relationships see Chart B. Use the multiplier times the allowable
radial load to predict different bearing life. See Allowable Radial Load Limits Section for load calculations.

Hot Oil Shuttle Endcover
A Hot Oil Shuttle is used to continuously remove a
portion of the fluid in a closed loop transmission or
other closed loop system. At 125 PSI pressure differential between the motor return port and the shuttle
outlet, 1.5 GPM* will exit the circuit to cool, filter and
return to the reservoir. The constant loop replenishment helps to keep heat and contamination from
building up in the circuit.

Introduction:
The SA Series Torqaxis™ is the most compact hydraulic motor in its class. It combines a small package with big
performance. The SA Series' low internal pressure drop means high mechanical efficiency and higher flow capability.
It can provide up to 7247 lb-in of output torque through a one piece solid shaft. This shaft design allows for full spline
contact between shaft and power element, reducing contact stresses and extending life. The solid shaft design also
allows for the shaft to be extended through the rear of the Torqaxis™ for mounting parking brakes, encoders or other
auxiliary drive devices.
Features:
•
•
•
•
Self-sealing and wear-compensating power element provides high volumetric efficiency throughout endurance
life of Torqaxis™
Solid one piece, fixed-axis output shaft-IGR™ concept ideal for constant reversal applications
Compact design for confined space applications

The allowable radial
load curve (Chart A) for
the SA series is based
on uni-directional
steady state loads for 12
x 106 revolutions and B10
bearing life. For different load-life relationships see Chart B. Use
the multiplier times the
allowable radial load to
predict different bearing
life. See “Allowable
Radial Load Limits”
section for load calculations.

Introduction:
The SB Series Torqaxis™ is a compact wheel motor designed with bearings to support the weight of a vehicle,
delivering up to 6645 lb-in of output torque in 4.6 inches of length. A parking brake or other auxiliary drive device can
be attached using the through shaft option, making this a very compact and versatile motor. The IGR™ power element
uses system pressure to seal against internal leakage for high volumetric efficiency. The shaft is of solid one piece,
fixed axis design, allowing full stationary spline contact between the shaft and the rotor. This reduces internal stresses,
allowing for higher torque transfer with long life.

Introduction:
The SH Series Torqaxis™ is a rugged motor for high torque, high side load applications. The SH Series motor
combines the efficient IGR™ orbit motor with a 4.1 to 1 planetary gear reducer for an integral package to suit the most
severe applications. With torque capabilities to 15,000 lb-in, this motor can withstand side loads to nearly 8000 lb.,
ideal for wheel drives and heavy industrial applications. The IGR™ power element utilizes system pressure for sealing
against internal leakage for improved volumetric efficiency. This design allows the power element to compensate for
its own wear, assuring no degradation of volumetric efficiency over the life of the motor. The motor utilizes a solid,
one piece fixed axis shaft, allowing full stationary spline contact between the shaft and the power element for low
spline contact stresses. The shaft can also be brought through the back cover for mounting a brake, encoder, or other
auxiliary functions.

The allowable radial load
curve (Chart A) for the
SH series is based on
uni-directional steady
state loads for 3x 106
revolutions and B10
bearing life. For different
load-life relationships see
Chart B. Use the multiplier times the allowable
radial load to predict
different bearing life. See
“Allowable Radial Load

Curves are based on 2000 hr. B-10 bearing life @
25 RPM, and at rated output torque. To determine
the allowable radial load at speeds other than
10,25,50 RPM, use the 25 RPM curve load values
in formula:

SL Series Torqaxis™
Introduction:
The SL Two Speed Series Torqaxis™ utilizes two separate IGR™ power elements on a common shaft. An integral
selector valve shifts between high torque, low speed and high speed low torque operation in a ratio of 2:1. The use of
two power elements eliminates the inefficiencies of traditional, one power element designs. In the high torque mode,
the motor delivers twice the torque and half the speed that it does in the high speed mode. The selector valve can be
open or closed center and may be actuated by an external pilot or optional solenoid valve. The open center selector
valve can be shifted “on the fly” while the motor shaft is rotating under load. The selector valve is spring loaded to
return to its pilot-pressure-off position. Normal mode of operation is field changeable and can be selected as series or
parallel. Pilot pressure must be 100 psi higher than motor case or outlet pressure and may be as high as typical
hydraulic system operating pressure.

Above load curve is for production dates 9/25/97 and later (Julian date 268-97).
The allowable radial load curve (Chart A) for the SL series roller bearing motor
is based on uni-directional steady state loads for 2,500,000 revolutions and B10
bearing life. For different load-life relationships see Chart B. Use the multiplier
times the allowable radial load to predict different bearing lifes.

SL Application Information
•
•
•
Minimum shift pressure is 100 PSI above case pressure.
Closed center valve will cause system pressure spikes when shifted while motor shaft is rotating. Recommended
for load holding applications.
If motors equipped with solenoid spool actuation must be shifted at motor flow rates below 4 GPM, use of
closed center spool is recommended.
Note: Open center valve allows the motor to
freewheel momentarily during shifting and is
not recomended for load holding applications.

SM Series Torqaxis™
Introduction:
The SM Two Speed Series Torqaxis™ utilizes two separate IGR™ power elements on a common shaft. An integral
selector valve shifts between high torque, low speed and high speed low torque operation in a ratio of 2:1. The use of
two power elements eliminates the inefficiencies of traditional, one power element designs. In the high torque mode,
the motor delivers twice the torque and half the speed that it does in the high speed mode. The selector valve can be
open or closed center and may be actuated by an external pilot or optional solenoid valve. The open center selector
valve can be shifted "on the fly" while the motor shaft is rotating under load. The selector valve is spring loaded to
return to its pilot-pressure-off position. Normal mode of operation is field changeable and can be selected as series or
parallel. Pilot pressure must be 300 psi higher than motor case or outlet pressure and may be as high as typical
hydraulic system operating pressure.

Above load curve is for production dates 9/25/97 and later (Julian date 268-97).
The allowable radial load curve (Chart A) for the SM series roller bearing motor
is based on uni-directional steady state loads for 2,500,000 revolutions and B10
bearing life. For different load-life relationships see Chart B. Use the multiplier
times the allowable radial load to predict different bearing lifes.
Allowable SM Series Side Load and Torque Limits
The only shaft available for the SM Series is a 7/8" 13 Tooth spline, which is limited to torque outputs of 3,000 lb-in
or less. When applying the motor, use the performance charts in this section to insure that torque requirements do
not exceed this value. Radial loads up to 400 lb are acceptable.
SM Application Information
•
•
•
Minimum shift pressure is 100 PSI above case pressure.
Closed center valve will cause system pressure spikes when shifted while motor shaft is rotating. Recommended
for load holding applications.
If motors equipped with solenoid spool actuation must be shifted at motor flow rates below 4 GPM, use of
closed center spool is recommended.
Note: Open center valve allows the motor to
freewheel momentarily during shifting and is
not recomended for load holding applications.

The solid one-piece shaft in our high performance
motors allows a brake to be mounted directly to an
extension of the main drive shaft. The male spline on
the motor slides directly into the female spline in the
brake described on the Multiple Disc Brake Accessory
page. The insertion of two bolts completes the
mounting procedure.
Features

Encoder Mount
The solid, fixed axis shaft utilized in our high
performance motors allows an extension of the
drive shaft to be brought through the rear cover.
An optional pad can be provided for easy mounting of many common encoders. The encoder is
driven directly by the drive shaft for extremely
accurate shaft speed or position sensing. In
combination with other electrohydraulic components the motor will provide very precise velocity,
positioning or other motion control.
To mount encoder, remove (4) socket head cap
screws attaching rear encoder mounting plate to
motor. Attach encoder and encoder mounting
plate to motor using (4) longer socket head cap
screws, furnished. Torque to (10) lb in.

Installation/Operation Information
Fluid
Thru-Shaft
To insure maximum motor performance and motor life,
use premium quality hydraulic oils. Fluids with effective quantities of anti-wear agents or additives are
highly recommended. If using synthetic fluids consult
the factory for alternative seal materials.
• Minimum fluid viscosity — 50 SUS
• Maximum permitted fluid temperature — 180° F
• Minimum recommended fluid filtration 25 micron
with a beta ratio of 2.
• API 10W40 SF or CD motor oil is usually
recommended.
Maximum torque should not exceed 5000 lb in static
or 3000 lb in dynamic on the optional thru-shaft. If
torque on the thru-shaft exceeds 3000 lb in when
attempting to dynamically brake a load, the Thru-Shaft
splines and/or shaft could fail and all braking action
could be lost.
Performance Data
Performance data shown in this catalog is the result of
testing performed using petroleum based fluid at
120° F, 180 SUS. Actual performance will vary with
fluid conditions. Lower viscosity will produce lower
performance.
Pressure
Run-In
Operating the motor in its intermittent pressure range
will shorten the life of the motor and should generally
be restricted to 10% or less of each minute. The
reduced life resulting from continuous operation in the
intermittent range may be acceptable in some applications. Consult the factory for details.
For optimum performance and life, a 15 minute run-in
period at no load and mid-flow conditions is recommended. Do not subject the system to full load until air
has been bled from the hydraulic system and all
contaminate particles have been filtered out.
Inlet Conditions
Case Drain
Positive pressure must be available at the motor inlet
while it is operating. If an overrunning load causes the
motor to rotate faster than the pump can fill it, cavitation will occur. Consult the factory for inlet pressure
requirements and speed limitations.
A check ball system drains the shaft seal to the outlet
port regardless of direction of rotation of the shaft.
This maintains low pressure on the shaft seal, reducing
heat and friction for long seal life. If high pressure
exists in the outlet port due to series operation, meterout circuitry or other causes, the shaft seal can be
externally drained to tank for low seal pressure. For
continuous operation with outlet pressures above 1000
psi use of the external case drain is recommended for
extended seal life.
Other Operating Conditions
Consult factory before operating at conditions exceeding any ratings or recommendations in this catalog.
Installation Recommendations
• To avoid contamination do not remove plastic port
plugs until fittings are to be installed.
• Motor mounting flange must make full contact with
equipment mount; do not use the mounting bolts to
force the motor pilot into the pilot hole to align the
motor.
• Pulleys, sprockets, wheels, or couplings should be
properly aligned on the shaft to avoid excessive
radial or thrust loads.
• To avoid damaging the thrust system, do not hammer on the motor or shaft to install or remove
couplings, pulleys, sprockets, etc.
Shaft Loading
Use of one inch keyed, 25mm keyed and 7/8-13 tooth
spline shafts are not recommended when torque loads
exceed 3000 lb in. Maximum thrust load on the shaft
should not exceed 2000 pounds, inward or outward on
the SH Series motors, 1000 pounds inward or outward
on all other Torqaxis™ Series.
Stainless Steel Shafts
Torque, speed, axial, and radial load ratings are
reduced by 10% when operating with the stainless
steel shaft that is optional on some series of motors.

Installation/Operation Information
Planetary Lubrication Instructions
(SH Series)
Oil
Gearbox is shipped dry. Before operating add EP-90 or
suitable equivalent oil to gearbox.
Oil Temperature
Heat is generated by the power transmitted through
the gearing. Since the gearing has an independent
lube supply, the amount of heat rejected from the oil
depends on the operating environment. Maximum
continuous gear lube temperatures of 160°F with
intermittent to 200°F will insure maximum gearing life.
Mounting Arrangement
Unit is designed to operate in the horizontal shaft
position, insuring gear lubrication. Consult factory if
unit is mounted in any other position.
Service
With the unit mounted horizontally, use any of the 6 fill
and drain plugs ( 3 on the shaft side, 3 on the hydraulic
port side ). Add oil until the unit is half full. A drain
plug on the horizontal center line can be removed to
determine appropriate oil level. Oil should be changed
after the first 50 hours or 50,000 revolutions. Subsequent changes should be done after each 1000 hours
of operation or one year, whichever comes first.
Low Speed Valve Option
An overlapped commutator valve is available to further
reduce internal leakage when operating at flow rates
below 10 GPM. Flows above 10 GPM through the valve
will result in higher pressure drops across the motor.
The Low Speed Valve is standard with all wheelmotors
and motors equipped with encoder mounts. Consult
the factory.

Vehicle Wheel Applications
Methods shown below for calculating vehicle drive requirements are
based on empirically-derived factors
and theoretical equations for fourwheeled vehicles with “normal”
tires, inflation pressures, and weight
distribution. The methods of
evaluation are useful for initial
identification of wheel drive application requirements, but should be
confirmed by performance and
durability testing on actual vehicles.
Tractive Effort (TE):
Tractive Effort is the tractive force
that the driven wheels exert on the
ground. The required Tractive Effort
is found by adding together the
forces due to Rolling Resistance,
Grade Resistance, Acceleration, and
Drawbar Pull. An allowance of 10%
should be included for starting
friction and air resistance. Thus:
TE = (RR+GR+F+DP) x 1.10 where:

Rolling Resistance (RR):
Rolling Resistance is the force
required to move a vehicle at a
constant speed over level terrain.
The magnitude of this force is
approximated by:
RR = GVW x R where:
RR = Rolling Resistance (lbs)
GVW = Gross Vehicle Weight
(lbs)
R = Rolling Resistance Factor
dependent upon type
and condition of surface.

Example: What is the Rolling Resistance of a vehicle having a gross
weight of 12,000 lbs on poor asphalt?
RR = 12,000 x 0.022 = 264 lbs
Grade Resistance (GR):
Grade resistance is the force required to move a vehicle at a
constant speed on a grade of a
given slope. Grade is a measure of
the severity of an incline and is
expressed in percent, representing
the number of feet rise in 100 feet of
horizontal distance.
For Example: A 5% grade indicates
a five foot rise over a 100 foot run.
Slope is another measure of an
incline and is expressed in degrees
from horizontal.
The force due to grade resistance
can be estimated by:
GR = 0.01 x GVW x G where:
GR = Grade Resistance (lbs)
GVW = Gross Vehicle Weight (lbs)
G = Grade (%)

Accelerating Force (F):
Accelerating Force is the average
force required to increase vehicle
speed from an initial velocity to a final
velocity in a specified length of time.
This force can be calculated by:
Knowing the required Tractive Effort
for the vehicle, Hydraulic Motor
Torque can be estimated by:
T=
TE x r
_______
where:
GxN
F=
V x GVW
__________
T x 32.16
where:
V = Change in Velocity (ft per
second) (Final Velocity Initial Velocity)
GVW = Gross Vehicle Weight (lbs)
T = Time for Velocity Change
(seconds)
Example: What force is required to
accelerate a vehicle having a gross
weight of 12,000 lbs from a velocity of 2
feet per second to a velocity of 10 feet
per second in a time of 10 seconds?
F=
8 x 12,000
_________
=299 lbs
10 x 32.16
Note: To convert vehicle velocity from
miles per hour to feet per second,
multiply by 1.467. For example, 5
miles per hour is equivalent to 5 x
1,467 = 7.34 feet per second.
Drawbar Pull (DP):
Drawbar Pull is the force a vehicle
can exert on a load in addition to the
force required to propel itself.
Drawbar Pull required to tow a
trailer, for example, can be calculated based on Rolling Resistance,
Grade Resistance, and Acceleration
Force for the towed vehicle.
Hydraulic Motor Torque
As noted above, total required
Tractive Effort is the sum of the
forces due to Rolling Resistance,
Grade Resistance, Acceleration, and
Drawbar Pull plus 10%:

Rolling Radius
The rolling radius should be based
on actual application factors such as
Plyrating, Rated Load and inflation
pressure can result in different
values.
The following chart will estimate the
wheel RPM -vs- vehicle velocity for
various rolling radii.
Hydraulic Motor
Torque Required to Slip
Wheels:
Slip Torque is particularly important
in systems where maximum hydraulic pressure across the motor is not
controlled by a relief valve. In this
case, wheel slip is the only limitation
on the pressure that can be applied
to the motor. Slip torque should be
calculated based on maximum
allowable vehicle overload conditions
and should include weight shift
anticipated during dynamic operating
conditions. If calculated slip torque
exceeds the intermittent torque rating
of a motor being used, a pressure
relief valve must be included in the
vehicle hydraulic system to regulate
pressure across the motor to a safe
level.
Hydraulic Motor Slip Torque is
calculated by:
ST =
VW x u x r

drives two rear wheels through a
differential having a reduction ratio

the rear tires have a rolling radius of
14 inches. Coefficient of friction
between tires and ground is estimated to be 0.65.

Example: What is the Hydraulic

the rolling radius of the driven tire is
16 inches? Gear reduction ratio
between hydraulic motor and driven
wheel is 8:1.
ST =
2400 x 0.65 x 14
______________

Note: If it is possible for the driven
wheels to back drive the hydraulic
motor during fast reversal of vehicle
direction or dynamic braking, calculated Hydraulic Motor Slip Torque
should not exceed the allowable
intermittent torque rating (70% of
intermittent pressure rating for
overrunning loads) for the hydraulic
motor being used. Consult the
factory for drive train fatigue life
projections on applications where
severe reversals are anticipated.
185
Overrunning Load or
Braking
If the hydraulic motor is to be used
for braking the vehicle or if it is
possible for the driven wheels to
back drive the hydraulic motor
under overrunning conditions, limit
the pressure to 70% of the allowable
intermittent pressure rating for the
motor selected.
To prevent cavitation during overrunning conditions, pressure at the
motor inlet port should not fall
below values determined as follows:
SA/SB/SH/SL/SM Motors —
Minimum inlet pressure =
S x D x V x .0004
where:
S = Motor Rotational Speed
(RPM)
D = Motor Displacement (in3/
rev)
V = Fluid Viscosity (SUS)
If the motor can overrun the pump
flow, the motor may cavitate and
become very noisy. Cavitation will
cause a reduction in motor life. For
assistance in eliminating cavitation,
consult the factory.
Allowable Radial Load Limits
Determining Radial
Load
Shock Loads
The radial or side load force should be
considered the vector sum of weight
and torque reaction components.
Before proceeding, determine your
torque levels.
When motors are used to stop a
load, the torque for any given
pressure must be multiplied by 1.45.
Below are some helpful equations
for calculating radial load:
Shock loading should be considered
when motors are used for direct
wheel drive. A shock factor of 4 to 1
should be used on vehicles using
pneumatic tires with no suspension.
A shock factor of 6 to 1 should be
used on unsprung vehicles with
solid rubber tires. The shock factor
should be multiplied by the static
weight (W) on that wheel. The
shock factor should not be used in
the Radial Load calculation. The
shock factor is for comparison in the
following step.

Ross Operation
After determining the radial load and
the shock load forces, use the
Allowable Radial Load Curves (Chart
A) in the section for the appropriate
Torqaxis™ Series to determine if
your loads are acceptable. The
Radial Load force should not be
above the value shown in the graph
for the load center line location
determined from the application.
The Shock Load force should not
exceed the allowable ratings by
more than 2 to 1. If both conditions
are met, then the application should
be acceptable.
Example: Assume
• Weight — 600 lbs/driven
wheel;
• SB 13 motor at 1500 PSI;
from performance charts,
equals approximately 2,550
lb-in torque;
• Side load center line is 3"
from the front mounting
face of the wheel mount
housing style;
• Rolling Radius is 7";
• Pneumatic tires.
Radial Load =
______________
√
(600)2 + (2550/7)2 = 702 lbs
Allowable radial load from Chart A
(page 125 for SB Series) is 2,200 lbs
at 3" from the mounting face.
Radial Load Check: Since 702 lbs is
less than 2,200 lbs, this application
check is acceptable.
Shock Load = 4 x 702 = 2,808 lbs
(For pneumatic tires)
Allowable shock load would be 2 x
2,200 lbs (From SB charts) of
4,400lbs.
Shock Load Check: Since 4,400 lbs
is greater than 2,808 lbs, the application check is acceptable.
As both the radial load and shock
load check are below that allowed,
the radial load life should be acceptable.

Design Advantages
Hydraguide™
Each Hydraguide unit consists of a directional control valve and metering
section. The valve directs the pressurized oil supplied to and from the
cylinder and the Hydraguide metering section. The metering section
“meters” out the pressurized oil to the steering cylinder.
The Hydraguide works in conjunction with the vehicle’s hydraulic system,
which consists of a steering cylinder(s), relief valve, reservoir, filter, fluid
lines, and an engine driven pump to comprise a complete system. The
systems must be tailored to the specific vehicle type and service for which
it will be used. Ross offers engineering advice and assistance (and
encourages use of our engineering assistance) when applying hydrostatic
steering to any vehicle.

System Terminology
Open Center, Nonreversing
Open Center, Reversing
The nonreversing unit keeps the
steered wheels in the steered
position when the operator releases
the steering wheel. The cylinder
ports are blocked in the neutral valve
position. The operator must steer
the wheels back to the straight
ahead position.
The reversing unit allows the steered
wheels to return to the straight
ahead position after the operator
releases the steering wheel. This
happens only if the steering
geometry exerts a centering force
on the steering cylinder. The
cylinder ports are interconnected
with the metering section so that the
steering wheel follows the wheels
back to center position.
Open Center,
Power Beyond (5-line)
The Hydraguide has an auxiliary fifth
port as a Power Beyond feature to
supply fluid to other functions
downstream of the Hydraguide
(Circuit #1). The Hydraguide
automatically takes priority flow for
steering, with the remainder
available for auxiliary functions.
When not steering, all flow is
available to auxiliary functions. This
system eliminates a flow divider or a
separate steering circuit, thus saving
energy and component cost.

Closed Center System
Closed Center, Nonreversing
Closed center systems utilize a variable displacement
pump providing variable flow to the steering circuit.
All ports of the Hydraguide™ are blocked when the
vehicle is not being steered. The amount of flow
through the steering circuit depends upon steering
speed and displacement of the Hydraguide.

Closed Center Load Sense
This unit is a closed center design with a sense line
for actuating the priority valve. Load sense is a flow
and pressure modulation principle that provides a
smooth steering transition. The function of the
priority valve is to ensure a supply of power oil to the
steering unit regardless of the downstream demand
of the auxiliary valve.

NOTE: If the auxiliary circuit requires a large demand from

minutes/revolutions)
HD= Hydraguide displacement

SS= Steering speed
(revolutions/seconds)
(Ideal speed of steer =
120 rpms.)
STEP X Select a relief valve
setting
The cracking pressure of the relief
valve, which is usually defined as the
pressure when the relief valve starts
to open and discharge flow to the
return line, should be greater than
the maximum pressure measured on
the vehicle.
The full flow pressure of the relief
valve, which is defined as the
pressure when maximum flow is
going over the relief valve, must not
exceed the pressure rating on the
steering unit.
Steering Speed
The minimum normally considered
is 1 rev/sec (60 rpm). An example
would be an articulated vehicle.
This depends on the safety
considerations for avoidance of
obstacles under minimum and
maximum flow conditions during all
speed possibilities of the vehicle.
1.5 rev/sec (90 rpm) is common, and
2 rev/sec (120 rpm) is considered
about the maximum input speed
achievable by an average person.
If the steering wheel speed becomes
greater than the pump flow, a
dramatic increase in steering wheel
effort is felt.
STEP IX Measure maximum
steering pressure
on prototype
vehicle
Compare this pressure with the
pressure rating of the Hydraguide. If
it is higher, return to the last part of
Step III and recalculate through Step
IX again.

HGF Series Introduction
Hydraguide™ brand hydrostatic steering units were developed to meet the
requirements of a broad range of off-highway applications. The HGF series
is designed for light duty applications such as lawn and garden equipment,
small agricultural equipment, small off-highway vehicles and some industrial
material handling equipment.
HGF Series Features
• Compact Size—The compact size of the HGF permits mounting in
tight spaces to add overall machine design flexibility.
• Full-Pressure Shaft Seal—The Ross full pressure input shaft seal is
able to withstand full system back pressure up to the pressure rating
of the Hydraguide. This enables operation of auxiliary hydraulic
functions downstream of steering.
• Pressure Dams—Pressure dams provide a barrier of pressurized
system oil between metered oil and return. Pressure dam valving
provides more precise steering due to the reduction of leakage oil
from the metering element.
• Needle Thrust Bearing—The needle trust bearing reduces input
torque required to steer, resulting in lower steering efforts.
• Removable/Servicable Upper Column Now Available.
• SAE #6 Female O-Ring Ports Standard.
• Integral Mounting Studs—Integral mounting bolts minimize
hardware cost and simplify installation, resulting in fewer service
parts.
• Manual Emergency Steering—A ball check valve allows manual
steering in emergencies when pump flow is interrupted. If the vehicle
is large enough to require more that 100 ft.-lb. steering wheel torque
in the manual mode, another means of emergency steering is
recommended.
• Integral Relief Available—Five pressure settings from 500 to 1740 psi.
Preset to protect steering unit from excessive system pressure.

HGA/HGB Series Introduction
The HGA and HGB series Hydraguide™ steering units are designed for
applications such as large agricultural equipment including tractors,
combines and other self-propelled, specialized harvesting equipment. In
addition, these units are frequently specified for many medium-to-heavyduty applications such as logging and construction equipment and marine
and mining applications.

HGA/HGB Series Features
• Full Pressure Shaft Seal—The Ross full pressure input shaft seal is able to withstand full system back
pressure up to the pressure rating of the Hydraguide. This enables operation of auxiliary hydraulic functions
downstream of steering.
• Linear Valve Spool—The linear valve spool is less subject to stick and damage in the event of system
contamination and allows generally better control.
• Pressure Dams—Pressure dams provide a barrier of pressurized system oil between metered oil and return.
Pressure dam valving provides more precise steering due to the reduction of lost leakage oil from the
metering element.
• Vaned Rotor (HGA Only)—The spring biased vanes in the rotor tips reduce leakage between pockets in the
metering group. This provides more precise and positive steering.
• Pressure Balanced Metering Group—All Ross designs utilize a pressurized envelope around the metering
package (rotor set—commutator to reduce slippage leakage and provide more precise steering control).
• Manual Emergency Steering—A ball check valve allows manual steering in emergencies when pump flow is
interrupted. If the vehicle is large enough to require more than 100 ft.-lb. steering wheel torque in the
manual mode, another means of emergency steering is recommended.
