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.

Ultra-High-Torque GT Timing Belt Pulleys

Pair these pulleys with the strongest timing belts we offer, Ultra-High-Torque GT Timing Belts. They can handle as much torque as roller chain. Their curved teeth fit snugly with matching belts for minimal play (backlash), so these pulleys are good for applications that require precise positioning. All are compatible with Gates Poly Chain GT timing belts.

Steel and Iron—Strong but best for dry environments since moisture will cause them to rust.

Bushing Bore—Quickly swap or service parts in tight spaces—no press-fitting or special tools required. Mount a bushing (sold separately) on your shaft and slide the pulley over it. As you tighten the included set screws, the bushing grips the shaft and draws it into the pulley, creating a final hold that is more secure than with set screws alone.
