About Belts

Measure your old V-belt, timing belt, or pulleys to find the right belt replacement if you don’t know the trade size.

Ultra-High-Torque GT Timing Belts

The strongest timing belts we offer. These are reinforced with carbon fiber and are comparable in strength to roller chain. Their curved teeth fit snugly with matching pulleys for minimal play (backlash), so these belts are good for applications that require precise positioning. Also known as Gates Poly Chain GT timing belts.

Abrasion-Resistant Urethane Rubber—Won’t break down or create dust while they run. Plus, they last longer than neoprene belts.
