We stock a range of quality Mi-Lock Pulleys & Bushes. Constructed from cast iron, this range of pulleys can handle both A and B section belts (NB. Pitch circle sizing is based on PCD of A section).
 
The ability to join multiple Mi-Lock pulleys together to make multi-groove pulleys of varying sections and sizes allows you to reduce your total inventory.

A variety of bushes with different shaft sizes combined with short and long reach bolt kits is how the variety of drives can be managed with only a few pulleys.
