R+W Coupling Technology Elastomer Coupling ES2 Series

Design: Two coupling hubs are concentrically machined with concave driving jaws. One side with an integrated torque limiter. The torque limiter is available in single position, multi position or full-disengagement versions. Temperature range: The temperature range is dependent on the choosen Elastomer insert. Torsional stiffness: Depends on the Elastomer insert. Backlash: Absolutely backlash-free. Fit tolerance: On the hub/shaft connection 0.01 to 0.05 mm. Material: Torque limiter: high strength hardened steel with rust protected surface (oxidized) Clamping hub D1: up to series 450 high strength aluminum, from series 800 and up steel Clamping hub D2: up to series 60 high strength aluminum, from series 150 and up steel Elastomer insert: precision molded, wear resistant, and thermally stable polymer Service life: R+W Torque limiters are maintenance-free and have an infinite life, if the tolerances are not exceeded. Non-standard application: Custom designs available upon request. Technical Data: rated torque from 2 - 900 Nm shaft diameter from 5 - 80 mm
