Super HC ® V-Belts
3V250 through 3V1400
5V500 through 5V3550
8V1000 through 8V5600
Gates Super HC V-Belts combine modern high capacity material with
the revolutionary “narrow” cross section pioneered by Gates. They can
transmit up to 3 times the horsepower of conventional V-belts in the
same drive space—or the same horsepower in 1/2 to 2/3 the space.
Super HC belts can be used on all industrial integral horsepower drives.
They are also suitable for low and high speed drives in those speed
ranges where conventional belts have limited capacity. In many cases,
they can replace high maintenance chain and gear drives. Super HC VBelts have exclusive Gates construction features for extra long drive life.
Super HC ® Molded Notch V-Belts
3VX250 through 3VX1400
5VX450 through 5VX2000
Gates Super HC Molded Notch V-Belts are designed for use where
conventional V-belts drives are impractical, where space, weight or
sheave limitations are present, and where increased horsepower
capacity of production is required and higher speed are necessary.
With smaller sheave diameters, these belts offer a higher horsepower
rating than any other V-belts on the market.
Super HC ® PowerBand® Belts
2/3V800 through 5/3V1400
2/5V500 through 5/5V3500
3/8V1000 through 5/8V6000
2/3VX250 through 5/3VX1400
2/5VX500 through 5/5VX2000
Gates PowerBand Belts were developed by Gates for drives subjected to
pulsating shock loads. These include applications such as compressors, rock
crushers, hammers or pug mills.
A PowerBand belt is made by joining together two or more Gates V-belts
with a permanent, high strength tie band. These readily bend over
sheaves as easily as multiple V-belts. However, the tie band keeps the
belts running in a straight line into the sheave grooves even under
violent pulsating or shock loads. And, these PowerBand belts cannot
turn over or jump off the drive. Gates PowerBand belts provide the most
advanced V-belt drive system available.

PredatorTM V-Belts
Gates Predator V-Belts are specially reinforced for demanding
applications such as those typically found in the wood and lumber
processing industry, mining, agriculture, oil field equipment and heavy
construction. This new generation PowerBand® Belt is made by joining
two or more Gates V-belts with a permanent, high-strength tie-band. It
bends as easily as multiple V-belts over sheaves, but the tie-band
keeps the belts from bending sideways. This lateral rigidity keeps the
belt running in a straight line into the grooves even under violent
pulsating or shock loads. It cannot turn over—or jump off. These extra
heavy-duty V-belts are constructed with a treated fabric cover, aramid
tensile and are oil and heat resistant. Available in narrow and classical
profiles, they are precision-matched to optimize performance.
Hi-Power ® II V-Belts
A24 through A180
B28 through B315
C48 through C420
D105 through D660
Hi-Power II V-Belts feature a composite multipurpose construction.
Concave sidewalls fill out, making uniform contact with the sheave
groove and distributing wear uniformly. The arched top provides
superior strength to prevent “dishing” and distortion of the tensile
section. The Flex-Weave® cover protects the core of the belt and its
extra flexibility allows the belt to bend easily in even the smallest
sheaves. Constructed with special rubber compounds, these belts
resist oil and heat, ozone, sunlight weather and aging. Its superior
length stability assures that Gates Hi-Power II V-Belts require less
retensioning and takeup during their service.

Hi-Power® II PowerBand® Belts
2/B62 through 5/B315
2/C68 through 5/C420
3/D144 through 5/D660
Recommended for all multiple V-belt drives exposed to pulsating loads
or heavy shock loads. Developed and patented by Gates, these
Hi-Power II Powerband Belts pull like multiple V-belts, yet have
additional lateral rigidity to eliminate problems caused by whipping
belts that turn over or come off the drive. These belts operate in
standard V-belt sheaves. The tensile section in each belt strand is
within the sheave groove and the tie-band does not touch the bottom of
the sheave. As a result, Hi-Power II PowerBand Belts operate without
slip at low tension (low tension results in lower bearing loads).
Tri-Power® Molded Notch V-Belts
AX21 through AX173
BX28 through BX300
CX51 through CX360
Especially suited for drives with smaller diameter sheaves, Gates TriPower Molded Notch V-Belts carry a higher horsepower rating than
conventional cross-section belts. A special compound provides oil and
heat resistance and helps resist ozone, sunlight, weather and aging. A
proprietary material surrounding the tensile members bonds the cords
and rubber during vulcanization into a unit that provides long service
without cord separation. Special notches molded into the belt during
manufacturing reduce bending stress. The edges of Tri-Power Molded
Notch V-Belts are precisely cut to exact dimensions to assure uniform fit
along the sides of sheave grooves.

Polyflex® JB ® Belts
5M 7M 11M
Recommended for high precision applications, Polyflex JB Belts can
operate at very high shaft speeds—in excess of 10,000 rpm. They run
on small diameter sheaves with high horsepower capacities and are
precisely manufactured without laps and layers to achieve a uniformity
not possible with traditional rubber construction belts. Gates special
urethane compound used in Polyflex JB Belts is resistant to fatigue,
wear, ozone and environmental conditions.
Micro-V ® Belts
J Section L Section M Section
Gates Micro-V Belts are extremely smooth running and are oil and heat
resistant. The truncated rib profile increases flexibility and allows the
belt to perform at very high speeds on smaller diameter sheaves.
Woven fabric rib surface improves wear resistance and provides a
clutching surface. Horsepower ratings exceed RMA standards.
Recommended for high-speed applications such as rock crushers,
drilling rigs, cranes, road paving equipment and many more.

How to Select the Correct V-Belt Drive Using Stock Sheaves and Belts
To Design a Drive, Follow These Three Steps:
Step 1 Find the Design Horsepower
Design Horsepower = (Service Factor) x (Horsepower
Requirement)
The selection tables for two-sheave speeddown drives, using
standard electric motors, start on Page 22. Information includes
driveN speed, sheave diameters, speed ratios, belt length, center
distance and belt horsepower ratings.
A. Select the proper Service Factor from Table No. 2. If your driveN
machine is not listed and you cannot find a machine with
comparable starting, running and shock load characteristics, turn
to Page 266 for assistance in selecting a Service Factor.
B. The horsepower requirement of the drive is usually taken as the
nameplate rating of the driveR. The actual load requirement of the
driveN machine may be used as the horsepower requirement if it
is known. This load must be used in those applications where a
small auxiliary machine is being driven from a large motor or
engine.
C. F in d design horsepower by multiplying the horsepower
requirement of the drive by the service Factor.
Before Selecting a V-Belt Drive,
You Need to Know Only These Four Things:
1. The type of application, machine, or work being done.
2. The horsepower rating and speed (RPM) of the driveR.
3. The speed (RPM) of the driveN machine or the required speed
ratio.
4. The approximate center distance required.
CLUTCHING DRIVES
Refer all clutching drive applications to the Product Application
Department, The Gates Rubber Company, Denver, Colorado. V-belt
drives which use the belt as a clutch require special consideration
because the heat generated by belt slip (during engagement and
disengagement) on some clutching applications can cause some V-Belt
tensile materials to shrink in length. The shrinkage may cause a belt,
which is already engaged and driving, to not declutch, or a declutched
belt may engage itself and start driving the machine unexpectedly.
Depending on the machine and circumstances, either situation could
prove dangerous to the machine operator or bystanders.
Belts specially designed to minimize or eliminate heat shrinkage may be
required.

Speed and Design Horsepower Determine the Proper
Cross Section
A. At the bottom of the appropriate Cross Section Selection Charts
following read across to the design horsepower of the drive,
interpolating if necessary.
NOTE:
If your point is near one of the lines, a good drive can be designed with
the cross section on either side of the line. Design drives using both
cross sections and select the most economical drive consistent with
your other requirements.
B. Read straight up to the rpm of the faster shaft. Interpolate if
necessary.
C. The cross section in the area surrounding the point of intersection
which you located is the proper belt cross section to use.

Step 3 Select the Drive — continued
Select the Drive
Locate the Proper Drive Selection Table for the Cross
Section You Selected.
Before following the steps below, refer to paragraph B of Step
3. It provides guidance in the selection process and serves as
a final judgment of your selection.
B. Final Judgment
While selecting or evaluating your drive, consider
these facts:
1. If you need to keep sheave face width at a minimum, select the
largest diameter drive from the group.
2. Larger diameter sheaves will also keep drive tension, and
therefore shaft pulls, at a minimum.
A. For Standard Motor Speeds:
1. Read down the driveN speed column which is headed by your
motor speed, to an rpm close to the desired driveN machine
speed. If you cannot find a driveN speed close enough to meet
your requirements, use the Drive Design Section to design with
the exact sheave diameters you need. See Page 201.
2. To the right, in the sheave diameter columns, you will find the
small and large sheave diameters to order for the drive. These
are the two sheaves that will provide the required driveN speeds.
Be sure that the motor sheave is equal to or larger than the
minimum recommended diameter shown in Table Nos. 3, 4 or 5
on Page 19.
3. Read to the right the center distance value closest to the one
specified. The drive components can usually be adjusted to
provide for this catalog value. Read up to the top of the column
for the correct V-belt for the drive.
4. Immediately below the table, you will find a color key for
identifying the horsepower correction factor. Jot down the
proper factor for the center distance you have selected.
5. Now continue to the right on the same line to the rated
horsepower per belt for your motor rpm.
6. Multiply the rated horsepower per belt by the horsepower
correction factor found from the color key to find the
horsepower per belt.
3. In addition, larger diameter sheaves will generally give a more
economical drive, but you should hesitate to select diameters
so large as to require only one belt — you sacrifice multiple-belt
dependability.
4. If you have limited space for your drive, consider using the
smallest diameter drive from the group. However, sheaves
on electric motors must be at least as large as the NEMA
minimum from Table Nos. 3, 4 or 5 on Page 19.
5. When your point on the cross section selection chart is near a
line, indicating that either of two cross sections can be used,
the larger section will generally give a more economical drive.
However, in the largest cross sections, this may require the use
of standard but nonstock sheaves. In this case the drive using
the small cross sections with stock sheaves will usually be
more economical.
C. Other Drives
1. For drives where driveR speed is other than standard electric
motor, see Example on Page 21.
For speedup drives, see Example on Page 210.
2. For special drives not explained here (quarter turn, V-flat, idler),
see Pages 247 through 254.
7. Divide the design horsepower for the drive by the horsepower
per belt to find the number of belts. The answer will usually
contain a fraction. Use the next larger whole number of belts.
If your drive requires more than the stock number of grooves,
there are two possibilities:
a. Use the diameters as selected and order the nonstock
number of grooves.
b. Turn to the drive design section and design a drive using
one or two nonstock sheaves. You may be able to design
a more economical drive by using larger sheaves (which
results in fewer belts) in conjunction with at least one stock
sheave.
8. Find the recommended installation and takeup allowances
from Table Nos. 38 to 41 on Pages 193 and 194.
9. Calculate the minimum and maximum deflection forces and
deflection distance used to statically tension the drive. These
values can be found in the Tensioning Section on Pages 212
through 215.
Your design is now complete. Specify Gates Super HC® V-Belts,
Hi-Power® II V-Belts, Tri-Power® Molded Notch V-Belts, Micro-V®
Belts, Polyflex® JB® Belts, Super HC PowerBand® Belts or Hi-Power
II PowerBand Belts when ordering. Gates PowerBand Belts are
available in combinations of 2, 3, 4 or 5 strand belts as needed to
equal the total number of belts.

Data in the white area of Table No. 6 are from NEMA Standard MG-1-14.42, November, 1978. Data in the gray
area are from MG-1-14.45, September, 1965. Data in the red area are a composite of electric motor manufacturers
data. They are generally conservative, and specific motors and bearings may permit the use of a smaller motor

NOTE: For a given motor horsepower and speed, the total belt pull is related to the motor sheave size. As this size decreases, the total belt pull
increases. Therefore, to limit the resultant load on motor shaft and bearings, NEMA lists minimum sheave sizes for the various motors. The
sheave on the motor (DriveR Sheave) should be at least this large.

Step 1
Results
Find the Design Horsepower
A. From Table No. 2 on Page 14, Service Factor is 1.2.
B. Horsepower requirement of the drive is 10.
C. Design Horsepower = 10 hp x 1.2 = 12 hp.
Step 2
Belt Section = 3VX
Select the Drive
A. Turn to the drive selection table for 3VX belts, Table No.
6 on Page 22.
1. Under the column for a motor speed of 1750 rpm, find
the driveN speed of 1636, closest one to the desired
1 6 3 5 r p m . T h e r e a r e f o u r s h e a v e d i a m e te r
combinations that give this speed. The small sheave
d i a m e t e r o f 2 . 2 " i s s m a l l e r t h a n th e N EM A
recommended minimum diameter of 3.8", and should
not be used.
2. Use the remaining combination of DriveR = 5.6" O.D.;
DriveN = 6.0" O.D. The 5.6" DriveR diameter is larger
than the NEMA minimum of 3.8".
3. On the same line to the right, the Center Distance
nearest to the desired 38" is 38.4". At the top of this
column 3VX950 V-belts are specified. This means that
using the two sheaves 5.6" O.D. and 6.0" O.D. with
V-belt 3VX950, the drive center distance will be 38.4"
(See Step 4 below.)
4. The 38.4" center distance lies in the gray area of the
table for which the color key at the bottom of Page 23
shows a 1.1 horsepower correction factor.
5. Read to the right, continuing on the same line as the
38.4" center distance, to the column headed 1750 rpm
to find the Rated HP per Belt. This value is 7.09.
6. The horsepower correction factor, 1.1 times the rated
horsepower per belt, 7.09, is 1.1 x 7.09 = 7.8. This is the
horsepower per belt.
7. The design horsepower divided by the horsepower per
belt/rib is 12 ÷ 7.8 = 1.5; or 2 belts required for the drive.
Step 4
Design Horsepower = 12
Select the Proper V-Belt Section
A. From Figure 1 on Page 15, a drive with Design Horsepower
of 12 and 1750 rpm of the faster shaft can use a 3VX section
Super HC V-Belt.
Step 3
Service Factor = 1.2
Pump Speed = 1636 rpm
Motor Sheave = 5.6" O.D.
Pump Sheave = 6.0" O.D.
Center Distance = 38.4"
V-Belt Number = 3VX950
Horsepower Correction Factor = 1.1
Rated Horsepower per Belt = 7.09
Horsepower per Belt = 7.8
Number of Belts = 2
Determine Installation and Takeup Allowance
A. Center distance allowances for installation and takeup from
Table No. 38 on Page 193, are 0.8" for installation and 1.5"
for takeup.
Shortest center distance = 38.4" - 0.8" = 37.6"
Longest center distance = 38.4" + 1.5" = 39.9"

Step 1
Results
Find the Design Horsepower
A. From Table No. 2 on Page 14, the Service Factor is 1.3.
B. Horsepower requirement is 75.
C. Design horsepower = 75 x 1.3 = 97.5
Step 2
Belt Section = 5V or 5VX
Select the Drive
A. Sheave and Belt Size
1. Calculate the Speed Ratio; 2000 rpm ÷ 1100 rpm = 1.82.
2. Turn to the Drive Selection Tables for 5V/5VX belts.
Table No. 7 on Page 44. Read down the Speed Ratio
column to find a value of 1.82.
3. The stock sheaves giving this speed ratio are 10.3" and
18.7" O.D.
4. Turn to Formula No. 2 on Page 204 and check sheave
rim speed of the driveR. This is approximately 5500
ft./min. which is satisfactory. (Less than 6500 ft./min.)
5. Reading across the same row containing the 10.3" and
18.7" sheaves, find a center distance of 43.0", with belt
5VX1320.
B. Determine Number of Belts Required
1. Find rated horsepower per belt = (Basic + Add-on) x
Correction Factor.
(a) Turn to Table No. 10 on Page 71 and find Basic
Horsepower of 37.2 for sheave size of 10.3" and
speed of 2000 rpm. On the same line across, find
add-on horsepower of 1.4 for speed ratio of 1.82.
Total is 37.2 + 1.4 = 38.6.
(b) Determine Correction Factor. At the bottom of Page
44 where belts and sheaves were selected, note
correction factor of 1.0 for C.D. of 43". Therefore the
38.6 horsepower from (a) above is unchanged.
c) Rated horsepower per belt = 38.6.
2. Divide the Design Horsepower by the Rated Horsepower per
Belt/Rib: 97.5 ÷ 38.6 = 2.5 or 3 belts.
Step 4
Design Horsepower = 97.5
Select the Proper V-Belt Section
A. From Figure No. 1 on Page 15, a drive with a Design
Horsepower of 97.5 and 2000 rpm of the faster shaft requires
a 5V or 5VX Section belt, Super HC Type. The belt section
finally selected will depend on length required.
Step 3
Service Factor = 1.3
Speed Ratio = 1.82
Engine Sheave = 10.3"
Fan Sheave = 18.7"
Sheave Rim Speed = 5500 ft./min.
Belt = 5VX1320
Center Distance = 43"
Basic HP = 37.2
Add-on HP = 1.4
Total HP = 38.6
Correction Factor = 1.0
Rated HP/belt = 38.6
3 belts required
Determine Installation and Takeup Allowance
A. From Table No. 38 on Page 193, find 1" for installation and
2.2" for takeup.
Installation Allowance = 1.0"
Takeup Allowance = 2.2"

Generally most ferrous materials have sufficient wear resistance for Polyflex JB
sheaves. However, it’s extremely important to evaluate the structural integrity of the
sheave. The forces due to the actual power being transmitted as well as centrifugal
forces (especially on drives over 6,500 feet per minute), should be checked before
selecting a material. Nonferrous and nonmetallic materials should be avoided due to
poor wear resistance. Nonmetallic material also lacks thermal properties for good heat
dissipation.

Generally most ferrous materials have sufficient wear resistance for Polyflex JB
sheaves. However, it’s extremely important to evaluate the structural integrity of
the sheave. The forces due to the actual power being transmitted as well as
centrifugal forces (especially on drives over 6,500 feet per minute), should be
checked before selecting a material. Nonferrous and nonmetallic materials should
be avoided due to poor wear resistance. Nonmetallic material also lacks thermal
properties for good heat dissipation.

The storage of power transmission belts is of interest to
users and distributors as well as manufacturers. Under
favorable storage conditions, good quality belts retain their
initial serviceability and dimensions. Conversely,
unfavorable conditions can adversely affect performance
and cause dimensional change. Good storage facilities and
practices will allow the user to achieve the most value from
belt products.
Power transmission belts should be stored in a cool and dry
environment with no direct sunlight. When stacked on
shelves, the stacks should be small enough to avoid excess
weight on the bottom belts which may cause distortion.
When stored in containers, the container size and contents
should be sufficiently limited to avoid distortion, particularly
to those belts at the bottom of the container.
Some things to avoid:
Do not store belts on floors unless a suitable container is
provided. They may be susceptible to water leaks or
moisture or otherwise damaged due to traffic.
Do not store belts near windows which may permit exposure to
sunlight or moisture. Do not store belts near radiators or
heaters or in the air flow from heating devices.
Do not store belts in the vicinity of transformers, electric
motors or other electrical devices that may generate ozone.
Also avoid areas where evaporating solvents or other
chemicals are present in the atmosphere.
Do not store belts in a configuration that would result in bend
diameters less than the minimum recommended sheave or
pulley diameter for normal bends.
Equipment using belts is sometimes stored for prolonged
periods (six months or more) before it is put in service or
during other periods when it is idle. It is recommended that
the tension on the belts be relaxed during such periods and
that equipment storage conditions should be consistent with
the guidelines for belt storage. If this is not possible, the belts
should be removed and stored separately.
Handling of Polyflex JB belts is also important. Due to the high
performance characteristics of Polyflex JB belts, do not crimp or
tightly bend the belt. Belts should not be bent inside tighter than
the smallest recommended sheave diameter for that particular
cross section (See Chart A on left). Backside bending should be
limited to the values specified in Chart B on left.

The belt may be cleaned by wiping with a rag slightly dampened
with a light nonvolatile solvent. Soaking or brushing on such
solvent is not advisable. The belt must be completely dry before
using on the drive. More obviously, sanding or scraping the belt
with a sharp object to remove grease or debris is not
recommended.
