Single Groove V-Belt Pulleys

Single groove V-belt pulleys are designed for simple power transmission between two shafts. They are commonly used in applications where only one belt is needed.

Double Groove V-Belt Pulleys

Double groove V-belt pulleys allow for the use of two belts, providing increased power transmission capacity and redundancy. They are ideal for heavy-duty applications.

Multiple Groove V-Belt Pulleys

These pulleys feature multiple grooves, enabling the use of several belts simultaneously. They are used in complex systems requiring high power transmission.

Variable Pitch V-Belt Pulleys

Variable pitch V-belt pulleys allow for adjustment of the pulley pitch diameter, providing flexibility in speed and torque control. They are used in applications requiring variable speeds.

Idler V-Belt Pulleys

Idler pulleys are used to guide or take up slack in a belt drive system. They do not transmit power but ensure proper belt tension and alignment.

V-Belt Pulley Components


The hub is the central part of the pulley that connects to the shaft. It provides structural integrity and ensures the pulley is securely attached.


The grooves in a V-belt pulley are designed to match the belt profile. They facilitate grip and efficient power transmission between the belt and pulley.


Flanges are raised edges on the pulley that prevent the belt from slipping off. They are essential for maintaining proper belt alignment and tension.

How to Choose or Customize the Right Belt Pulley
