Types of V-Belt Pulleys

Classical V-Belt Pulleys

Classical V-belt pulleys are widely used in various industrial applications. They have a standard design that fits most V-belts, making them a versatile choice for different systems.

Narrow V-Belt Pulleys

Narrow V-belt pulleys are designed for high power transmission in compact spaces. Their narrower profile allows for efficient power transfer and is ideal for applications where space is limited.

Double-Sided V-Belt Pulleys

Double-sided V-belt pulleys can drive multiple belts simultaneously. This design is particularly useful in complex machinery where multiple components need to be driven by a single power source.

Variable Speed V-Belt Pulleys

These pulleys allow for adjustable speed control. They are used in applications where variable speeds are required, providing flexibility and efficiency in power transmission.

V-Belt Pulley Components


Sheaves are the grooved wheels that guide and hold the V-belts in place. They come in various sizes and materials, depending on the application and belt type.


Bushings are used to mount the pulley onto the shaft. They provide a secure fit and help in reducing vibration and wear, ensuring smooth operation.


Flanges are used to keep the belts aligned on the pulleys. They prevent the belts from slipping off the pulleys, ensuring consistent power transmission.


Keyways are slots cut into the pulley and shaft to accommodate keys. These keys lock the pulley to the shaft, preventing it from rotating independently.

Choosing or Customizing the Right Belt Pulley

Load Requirements

Consider the load that the pulley will need to handle. This includes both the weight and the force exerted by the belt. Selecting a pulley with the appropriate load capacity ensures reliable performance.

Belt Compatibility

Ensure that the pulley is compatible with the type of belt you are using. Different belts require specific pulley profiles for optimal performance. Compatibility is crucial for efficient power transmission.

Environmental Conditions

Take into account the operating environment. Factors such as temperature, humidity, and exposure to chemicals can affect the performance of the pulley. Choose materials and designs that can withstand these conditions.
