Classical V-Belt Pulleys

Classical V-belts are the most commonly used type, characterized by their trapezoidal cross-section, which provides excellent grip and power transmission.

Narrow V-Belt Pulleys

Narrow V-belts are designed for higher load capacities and increased efficiency, ideal for compact and high-torque applications.

Double V-Belt Pulleys

Double V-belts, or hexagonal belts, allow for power transmission on both sides of the pulley, making them suitable for complex mechanical systems.

Synchronous V-Belt Pulleys

Synchronous V-belts feature teeth that mesh with corresponding pulley grooves, ensuring precise timing and minimal slippage.

Variable Speed V-Belt Pulleys

These pulleys allow for adjustable speed control, accommodating variable load requirements and operational conditions.

V-Belt Pulley Components


The hub is the central part of the pulley, designed to fit onto the shaft, ensuring secure attachment and alignment.


The flange provides structural support to the belt, preventing lateral movement and maintaining alignment during operation.


The groove is the part of the pulley where the belt sits, designed with specific angles and dimensions to maximize grip and efficiency.


The bore is the central hole through which the pulley is mounted onto the shaft, often finished to precise tolerances for a tight fit.


The keyway is a slot that accommodates a key, locking the pulley to the shaft and preventing rotational slippage.
