840-8M-20 high torque drive (HTD) timing belts’ curvilinear tooth design improves stress distribution to provide high horsepower ratings over a wide speed range and high torque transmission at low speeds. They are made of highly durable rubber compound with a glass cord tension member. Belt drives are 99% efficient, leading to significant energy savings on high horsepower applications. The belts are thin and flexible, so they don’t generate heat build up delivering long service life. The rounded tooth profile meshes precisely with matching pulley grooves so there is no belt creep or slip to cause speed variation. Continuous, helically-wound S and Z oriented fiberglass cord is the load-carrying muscle of the belt, resisting elongation and shock loads while providing excellent strength and service life.
