    Keep your drive system in sync. Trapezoidal teeth mesh with matching pulleys to transmit power without slipping. With the original tooth profile, these timing belts handle enough torque and synchronization for most applications. If you need high torque or precise starts and stops, consider curved tooth profiles, such as GT and HTD belts.
    Neoprene—Durable and weather resistant, but lose elasticity if exposed to oil and fuel. These belts are reinforced, so they're strong enough to transmit power without stretching. Plus, nylon-coated teeth minimize friction and protect the surface from wear.
    Abrasion-Resistant Urethane Rubber—Won’t break down or create dust while they run. Plus, they last longer than neoprene belts. Aramid or steel reinforcements provide very high strength and low stretch.
    High-Temperature Silicone Rubber—The best for extreme heat, silicone timing belts resist sterilizing temperatures that would degrade other rubber. All are reinforced with aramid for very high strength and low stretch.
