V-Belt Pulley Components


Flanges on V-belt pulleys help keep the belt aligned and prevent it from slipping off. They provide additional support and ensure smooth and efficient operation.


Hubs are central components that connect the pulley to the shaft. They provide stability and ensure that the pulley remains securely attached to the rotating shaft.


Grooves on V-belt pulleys are designed to match the profile of the V-belt. They ensure proper belt seating and enhance power transmission efficiency by providing optimal grip.


Keyways provide a means for locking the pulley to the shaft, preventing relative motion between the two. This ensures that the pulley and shaft rotate together without slippage.

Set Screws

Set screws secure the pulley to the shaft, providing additional locking force. They are commonly used in conjunction with keyways to ensure a robust and reliable connection.

How to Choose or Customize the Right Belt Pulley
