V-Belt Pulley Components


The grooves in a V-belt pulley are designed to match the profile of the V-belt, ensuring proper grip and efficient power transmission.


Flanges on V-belt pulleys help to keep the belt in place, preventing it from slipping off during operation.


The bore of a V-belt pulley is the central hole through which the pulley is mounted on the shaft. It must be precisely machined for a secure fit.


The keyway is a slot in the bore that accommodates a key, ensuring the pulley and shaft rotate together without slipping.


The hub is the central part of the pulley that connects the bore to the outer rim. It provides structural support and stability.

Selecting or Customizing the Right Belt Pulley

Determine Load Requirements

Understanding the load requirements is crucial for selecting the right belt pulley. This includes the amount of torque and power that needs to be transmitted.

Consider Speed

Speed is another essential factor. The pulley must be capable of operating at the desired speed without compromising performance or safety.

Environmental Conditions

The operating environment, including temperature, humidity, and exposure to chemicals, should be considered when selecting materials and designs.

Compatibility with Belts

Ensure the pulley is compatible with the type of belt being used. This includes matching the belt profile and size with the pulley¡¯s grooves.

Customization Options

If standard pulleys do not meet the specific requirements, consider customizing the pulley. This can include special materials, coatings, or unique design features.
