Types of Aluminum Pulleys

When it comes to aluminum pulleys, there are different shapes and sizes available to cater to various needs. Some common types include:

V-Belt Pulleys

These pulleys have a V-shaped groove that accommodates V-belts, which are commonly used for power transmission in machinery and automotive applications.

Timing Belt Pulleys

Also known as adjustable speed pulleys or variable pitch pulleys, these pulleys have movable flanges that can change the effective diameter of the pulley, allowing for variable speed transmission.

Variable Speed Pulleys

These pulleys have teeth around the circumference to mesh with the teeth of a timing belt, providing precise power transmission in applications requiring synchronized movement, such as in engines and robotics.

Sheave Pulleys

Commonly used in lifting and hoisting systems, sheave pulleys have a grooved wheel that supports and guides ropes or cables, providing mechanical advantage in lifting heavy loads.

Conveyor Pulleys

These pulleys are specifically designed for use in conveyor belt systems, providing the driving force for the movement of materials along the conveyor.
