Timing Belt Pulleys

Timing belt pulleys are grooved wheels that are part of the timing belt system. They are used to maximise power transmission through your machinery. Common applications include vehicles, printers and manufacturing equipment. 


How do timing belt pulleys work?

Timing belt pulleys have either teeth or pockets around the outside diameter. The timing teeth engage holes in the timing belt, while timing pockets engage drive lugs (fasteners) on a belt's inner circumference. 


Both cause frictional forces between the flat belt and the pulley surface. This not only enables the driving motion of the system, but helps to avoid speed variations and slippage, meaning you can more easily maintain and control the speed of your machine. 


Timing belt pulleys come in a range of materials including aluminium, steel and iron. This design makes them strong, heat resistant and durable, and also ensures a noiseless output.

 
Choosing your timing belt pulley

You can choose the correct timing belt pulley for your system according to the width of your timing belt.
