V-Belt Pulley Components


The sheave is the wheel component of the pulley that the belt runs over. It is crucial for guiding and supporting the belt during operation.


The groove in a V-belt pulley ensures that the belt stays in place and provides the necessary traction for efficient power transmission.


The bore is the central hole of the pulley through which it is mounted on a shaft. Precision in the bore size is essential for proper alignment and operation.


The keyway is a slot in the bore that accommodates a key, ensuring that the pulley remains securely attached to the shaft without slipping.


The flange is an optional component that provides additional support and prevents the belt from slipping off the pulley.

Choosing or Customizing the Right Belt Pulley

Load Requirements

Determine the load requirements of your application to select a pulley that can handle the stress without deforming or failing.

Speed Ratio

Consider the desired speed ratio between the driver and driven shafts. This will influence the pulley diameters and the type of belt used.

Material Selection

Choose a material that suits your application's environmental conditions and durability requirements. Common materials include steel, aluminum, and plastic.

Environmental Conditions

Consider the operating environment, including temperature, moisture, and chemical exposure, to select a pulley that can withstand these conditions.

Customization Needs

If off-the-shelf pulleys do not meet your needs, consider custom pulleys. Provide detailed specifications to the manufacturer to ensure the pulley meets your requirements.
