V-Belt Pulley Components

Understanding the components of V-belt pulleys is crucial for their effective application:


The hub is the central part of the pulley that connects it to the shaft. It must be durable to handle the rotational forces.


Flanges on either side of the pulley help keep the belt aligned and prevent it from slipping off during operation.


The groove is the part of the pulley where the belt sits. It must be precisely machined to ensure proper belt fit and function.


Bearings reduce friction and allow for smooth rotation of the pulley. High-quality bearings are essential for longevity.

Set Screws

Set screws secure the pulley to the shaft, ensuring a firm connection that can handle the operational stresses.

Choosing or Customizing the Right Belt Pulley

Selecting or customizing the right belt pulley involves several key factors:

Load Capacity

Understanding the load requirements of your system is crucial for selecting a pulley that can handle the expected forces without failure.
