Types of V-Belt Pulleys

Standard V-Belt Pulleys

These are the most common type of V-belt pulleys, used in a wide range of applications due to their simplicity and efficiency.

Deep Groove V-Belt Pulleys

Deep groove pulleys provide better belt alignment and support, reducing the risk of belt slippage and improving transmission efficiency.

Variable Speed V-Belt Pulleys

Designed for applications that require variable speeds, these pulleys allow for easy adjustment of the drive speed without changing the belt.

Multiple Groove V-Belt Pulleys

These pulleys accommodate multiple belts, distributing the load evenly and enabling higher power transmission capacity.

V-Belt Pulley Components


The bore is the central hole of the pulley where the shaft is inserted. Proper bore size is crucial for secure fitting and efficient power transmission.


Flanges are the raised edges on either side of the pulley, which help in keeping the belt aligned and prevent it from slipping off.


The keyway is a slot cut into the pulley bore and shaft, into which a key is inserted to lock the pulley in place, preventing it from rotating on the shaft.


The groove is the V-shaped channel that grips the belt. The groove angle and depth must match the belt profile for optimal performance.

Choosing or Customizing the Right Belt Pulley

Load Capacity

Determine the load capacity the pulley needs to handle. This includes both the static and dynamic loads to ensure the pulley can withstand the operational forces.

Material Selection

Choose the appropriate material for the pulley based on the environmental conditions, such as temperature, humidity, and exposure to chemicals.

Belt Compatibility

Ensure the pulley is compatible with the type of belt used. Different belts, such as V-belts, round belts, and flat belts, require specific pulley profiles.

Operational Speed

Consider the operational speed of the conveyor system. High-speed applications may require pulleys with precision balancing and robust construction.

Custom Design Specifications

If standard pulleys do not meet the requirements, work with manufacturers to customize the pulley design. This includes specific dimensions, bore sizes, and groove profiles.
