V-Belt Pulley Components


The hub is the central part of the pulley that attaches to the shaft. It is typically made of strong materials such as steel or cast iron to ensure a secure connection.


The rim is the outer edge of the pulley where the belt makes contact. The rim's surface is usually designed with grooves to ensure optimal grip and prevent slippage.


Spokes connect the hub to the rim, providing structural support and maintaining the pulley¡¯s shape. In some designs, spokes are replaced with a solid web for added strength.


The bore is the hole in the center of the hub through which the shaft passes. It is often precision-machined to match the shaft's dimensions, ensuring a tight fit.


The keyway is a slot within the bore that accommodates a key, preventing the pulley from rotating independently of the shaft. It ensures torque transmission between the shaft and pulley.

Choosing or Customizing the Right Belt Pulley

Load Capacity

When selecting a belt pulley, it is crucial to consider the load capacity. Ensure the pulley can handle the operational load without compromising performance or safety.

Environmental Conditions

Consider the environmental conditions, such as temperature, humidity, and exposure to chemicals, where the pulley will operate. Choose materials and designs that can withstand these conditions.

Belt Compatibility

Ensure the pulley is compatible with the type of belt used in your system. Different belts require specific pulley designs to achieve optimal performance and longevity.

Size and Dimensions

Accurate sizing and dimensions are essential for ensuring proper alignment and tension. Measure the shaft, bore, and overall dimensions to match the pulley to your system requirements.

Material Selection

Selecting the right material for the pulley is vital for its durability and performance. Common materials include steel, cast iron, and aluminum, each offering different strengths and benefits.
