F.N.Sheppard & Co. 8w0w0w. f-n 7sh3e3pp -a r5d7.c7o3m 29 TIMING BELTS – Urethane Molded Endless TIMING BELTS – Silicone Rubber Urethane Construction Urethane offers extremely good abrasion resistance. Low wear means that the belts will be very clean running, with no accumulation of debris. Urethane teeth are much harder than traditional neoprene teeth, which contributes to the belts overall stiffness. This makes Truly Endless Belts ideal for high precision, positioning applications. Reinforcing Cords Our standard reinforcing material is steel cord. For some pitches, we can also supply Kevlar® cord or polyester cord. The cord with the optimum physical properties can be selected to maximize performance. Some considerations may include tensile strength, stretch, and flex-fatigue properties. Molded Endless Belts are designed for power transmission and positioning applications. These belts are produced in a truly endless form. Having no splices or seams, they are ideal for higher torque drives. Produced with a high quality urethane body and steel reinforcing cords, and in some cases Kevlar® or polyester cords. Truly Endless Belts offer many advantages over traditional neoprene belts. Urethane is also chemical resistant. • Molded endless, no seam or splice • Temperature range up to 500º Fahrenheit • Chemical resistance • Glue release • Low thermal conductivity • Additional backings available, molded integral with the base belt • FDA compound available
