bearing without loosening
tie rods. Some limitations
apply.
4) PISTON ROD:
Piston rods up to and including 4.50” diameter have a
minimum yield of 100,000
PSI. Rod diameters over
4.50” use 50,000 PSI yield
steel. All rods are hard
chrome plated and polished
to resist wear and corrosion.
FEATURES AND SPECIFICATIONS
8) HEAD CUSHION:
Floating head end cushions

COLUMN STRENGTH
STOP TUBE & ROD SELECTION
The cylinder piston rod, and in some situations
(mount dependent) the cylinder acts as a column subject to both
compressive stress and buckling loads created as the result of
the mount selection, length of stroke and orientation of installation.
During full cylinder extension the introduction of a
'Stop Tube' acts as a spacer between the piston and rod bearing to
reduce bearing side load. The stop tube does not improve column
strength.
The standard rod diameter/bore size configuration is recommended (especially in 'Pull' applications) unless the application requires greater column strength.
SELECTING ROD DIAMETER - For Specific Bore Size:
From the opposite page determine the potential thrust for the selected cylinder bore. Using the data provided herein determine the
value of 'M', including any adjustment for stop tube. In the chart
'VALUE OF M' locate the row corresponding to thrust and along the
row locate the value 'M', and then read up the column to determine
the required rod diameter.
TO DETERMINE THE VALUE OF 'M':
Rigid Mount - Front (ME5; MF1,5; MS2,3,4,7; MX1,3)
M = Stroke + Dimension W
Rigid Mount - Rear (ME6; MF2,6; MX2)
M = Stroke + Applicable Dimension ZT or ZJ
Clevis Mount (MP1,2)
M = Stroke + Applicable Dimension XC or XD
Front Trunnion Mount (MT1)
M = Stroke + Dimension XG
Intermediate Trunnion Mount (MT4)
M = Stroke + Dimension XI
Rear Trunnion (MT2)
M = Stroke + Dimension XJ
USE OF CHART - VALUE OF 'M':
Horizontal cylinder applications are limited to the
values of 'M' shown within the bordered area; Vertical
cylinder applications require no such limitation.
STOP TUBE REQUIREMENT - If Any:
Stop tube length 'ST' is determined using the following:
ST = (E - 40) / 10
Where:
E = M / 2 .....
firmly guided rod end
E = 4M ........
unsupported rod end
E = M ..........
supported rod end
CHART - VALUE OF ‘M’ IN INCHES FOR VARIOUS ROD DIAMETERS*

PISTON / FLUID VELOCITY
C
SERIES
PISTON AND SYSTEM FLUID SPEED RELATIVE TO PORT SIZE
AND CUSHION REQUIREMENTS
The chart to the right provides a guide in determining the adequacy
of standard cylinder ports relative to application. The information provides
piston speed in feet per minute, by bore size for standard NPTF ports, system connected using Schedule 80 pipe with a fluid velocity of 15 feet per
second.
Piston speed is a function of fluid velocity in the connecting lines,
generally expressed in gallons per minute (GPM) and measured as the
input/exhaust flow through the cylinder cap end port.
System fluid velocity should not exceed 15 feet per second in order
to minimize the effect of fluid turbulence, pressure drop and hydraulic shock
loading. If fluid velocity through the cylinder ports exceeds 15 feet per second, consider port enlargement or twin ports.
Circumstances involving heavy loads or piston speeds in excess of
20 feet per minute wherein the piston completes full stroke, cushions are
recommended. Cylinder cushions increase cylinder life, reduce piston impact speeds and hydraulic shock.
