L Series Timing Belts
Neoprene is reinforced with fiberglass for quiet operation with high strength. Belts are L series (light) and have trapezoidal teeth. The teeth are nylon coated to protect the wear surface and minimize friction.
L Series Dust-Free Timing Belts
Urethane has excellent abrasion resistance, so these belts don’t create dust while they run. They are L series (light) and have trapezoidal teeth. Reinforced with Kevlar or steel, both materials provide very high strength, low stretch, and excellent shock resistance. Kevlar has higher shock resistance than steel.

L Series Heat-Resistant Timing Belts
Withstanding temperatures up to 400° F, silicone is the best choice for use in hot environments. Belts have Kevlar reinforcement, which has very high strength, low stretch, and excellent shock resistance. All are L series (light) and have trapezoidal teeth.
