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 Timing Belts with Teeth on Both Sides

Use a single belt to drive three or more pulleys in reversing and serpentine drive systems. These belts have teeth on both sides to transmit power from either side and rotate pulleys in opposite directions. Belts are neoprene with fiberglass reinforcement for quiet operation with high strength. They are L series (light) and have trapezoidal teeth. The teeth are nylon coated to protect the wear surface and minimize friction.
