MXL Series Dust-Free Timing Belts

Urethane has excellent abrasion resistance, so these belts don’t create dust while they run. They have Kevlar reinforcement, which has very high strength, low stretch, and excellent shock resistance. Belts are MXL series (miniature extra light) and have trapezoidal teeth.

MXL Series Cut-to-Length Timing Belts

Used to drive small-scale linear motion applications, these belts are neoprene with fiberglass reinforcement for quiet operation with high strength. Belts are MXL series (miniature extra light) and have trapezoidal teeth. The teeth are nylon coated to protect the wear surface and minimize friction.

These belts have a maximum continuous length of 50 feet.

High-Strength Ultra-Quiet Timing Belts

Curved Teeth

Also known as GT profile belts, belts with curved teeth minimize vibration and noise output. The teeth distribute pressure uniformly, so they wear evenly and last longer. Close engagement of the tooth and pulley offers more precise timing in heavy-load systems than trapezoidal teeth and HTD belts. Belts are neoprene, which is flexible and operates quietly. The fiberglass reinforcement on these belts add greater durability.
