Types of Belt

A / B / C / Z Section Belts

These type of belts are known as classical vee belts. If the section is suffixed with an 'X', this indicates that the belt is cogged to allow fitting at tighter angles.

SPA/SPB/SPC/SPZ Section Belts

SP denotes that the belt is a wedge belt. Again, an 'X' suffix indicates a cogged fitting.
