Types of Belt

Imperial Timing Belts

These belts have a trapezoidal tooth profile, providing a positive drive by meshing the belt teeth with the grooves of a relating timing belt pulley.

HTP Timing Belts

HTP stands for high torque power. These belts are able to handle a higher load.

Metric Timing Belts

Metric belts are the same as our imperial range, but the sizes are measuring in mm.
