H Series Timing Belts


Good for use in general purpose drive systems, these belts combine quiet-running neoprene with high-strength fiberglass reinforcement. They are H series (heavy) and have trapezoidal teeth. The teeth are nylon coated to protect the wear surface and minimize friction.

H Series Dust-Free Timing Belts


Urethane has excellent abrasion resistance, so these belts don’t create dust while they run. Belts have steel reinforcement, which has very high strength, low stretch, and excellent shock resistance. All are H series (heavy) and have trapezoidal teeth.
