V Belt Pulley Manufacturer in Ahmedabad
Pulleys
V pulleys for heavy, everyday power transmission
Cast iron V belt pulleys in classical A to E, wedge SPZ to SPC and narrow 3V to 8V sections, single, double or multi groove, from 2 in to 100 in diameter. Pilot, keyed, taper lock or QD bore.
V belt pulleys, also called V pulleys or sheaves, drive one or more V belts from the motor to the machine. They are the workhorse of mills, crushers, compressors and pumps, where a robust, easy to maintain drive matters more than exact timing.
We make pulleys in single, double and multi groove designs, with solid, arm or plate webs, and finish the bore to suit your shaft: set screw, keyway, taper lock or QD.
They are designed for easy installation, long life and dimensional accuracy, with a smooth surface finish and low maintenance needs. V belt pulleys are used in automotive applications, conveyors, cranes, lifts and other heavy machinery, and we also make them to your own specification.

Belt sections
Classical A to E and wedge SPZ to SPC pulleys
Choose the belt family. Grooves are machined to the matching standard for the section and pulley size.
Classical V belts
Classical: A to E
The traditional section range, found on most older and general purpose drives.
| Section | Nominal belt top width | Typical drives |
|---|---|---|
| A | 13 mm | Light to medium duty |
| B | 17 mm | Medium duty, the most common |
| C | 22 mm | Heavy duty |
| D | 32 mm | Heavy industrial |
| E | 38 mm | Very heavy industrial |
Wedge (SP) V belts
Wedge: SPZ to SPC
Narrower, deeper wedge belts that carry more power in less width than classical sections.
| Section | Nominal belt top width | Typical drives |
|---|---|---|
| SPZ | 9.7 mm | Compact light and medium drives |
| SPA | 12.7 mm | Medium duty |
| SPB | 16.3 mm | Medium to heavy duty |
| SPC | 22 mm | Heavy duty |
Narrow V belts, inch
Narrow: 3V, 5V, 8V
Inch based narrow sections, common on imported machinery.
| Section | Nominal belt top width | Typical drives |
|---|---|---|
| 3V | 3/8 in | Light to medium duty |
| 5V | 5/8 in | Medium to heavy duty |
| 8V | 1 in | Heavy duty |
Fractional horsepower
Light duty: 2L to 5L
Small sections for fractional horsepower drives such as fans and light machines.
| Section | Nominal belt top width | Typical drives |
|---|---|---|
| 2L | 1/4 in | Very light duty |
| 3L | 3/8 in | Light duty |
| 4L | 1/2 in | Light duty |
| 5L | 21/32 in | Light to medium duty |
Tell us the belt section and number of grooves. Pitch diameter, groove angle and groove spacing are machined to the matching standard.
Types
Single, double and multi groove V pulleys
-
Single groove
One belt, for simple, lower load drives.
-
Double groove
Two belts share the load for more power.
-
Multi groove
Several belts for heavy, high power drives such as crushers and expellers.
-
Arm and solid web
Spoked cast iron for large diameters, solid web for smaller pulleys.
-
Idler and variable speed
Idler, companion and variable speed styles on request.
-
Made to drawing
Special diameters, hubs and groove counts to your drawing.
Fit to your shaft
Pilot, taper lock and QD bore options
-
Pilot bore
A rough bore for you to finish to your own shaft.
-
Keyway and set screw
Bored to size with keyway and set screws, ready to fit.
-
Taper lock bore
Takes a standard taper lock bush, no reboring needed.
-
QD bore
For flanged QD bushings, easy to pull off.
Ordering
How to specify a V belt pulley
-
Belt section
Read the code on the belt, or measure its top width.
-
Number of grooves
Count the belts that run on the pulley.
-
Pitch or outside diameter
This sets the speed ratio of the drive.
-
Bore and hub
Bore type, keyway and hub position.

FAQ
V belt pulleys: common questions
Quick answers for maintenance and purchase teams.
Read the code printed on the old belt, such as B or SPB. If it has worn off, measure the top width of the belt: about 17 mm is a B section and about 16 mm is SPB. Wedge SP belts are deeper than classical belts of a similar width.
The belt section, the number of grooves, the pitch or outside diameter, and the bore: pilot, finished with keyway, taper lock or QD. Add the hub position if it is not central.
Yes. We make V belt pulleys with pilot bores, finished bores with keyway and set screws, taper lock bores and QD bores.
We make V belt pulleys from 2 in up to 100 in diameter, single or multi groove.
Aluminium, mild steel, stainless steel, cast iron, Delrin, nylon and EN series steels. Aluminium suits light, fast drives, mild steel and EN series steels suit high torque and wear, stainless steel suits washdown areas, cast iron suits large heavy parts, and Delrin or nylon suit light, quiet drives.
