Endless PU timing belts are made of wear-resistant polyurethane and high-tensile steel cord tension members. The unique properties of polyurethane timing belts include their outstanding performance potential, enormous strength and dimensional precision. The timing belts are temperature-resistant at ambient temperatures of -30°C to +80°C, their load capacity, even at high speeds, and uniform load distribution during power transmission enables them to have a diverse range of uses in drive technology. The extensive range of different polyurethane compounds also permits their use in specialist areas (e.g. in the food industry).
Polyurethane timing belts are offered in a range of high-performance profiles.
