R+W Coupling Technology Elastomer Coupling ESL Series

Design: Our zero backlash elastomer coupling incorporated with our torque limter. Available disengagement mode/Function system for all series: multi-position 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 Detent balls made of hardend steel Clamping hubs: high strength aluminum. 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. Speeds: Negligible abrasion by disengagement till 200 rpm. Higher speeds upon request. Technical Data: rated torque from 9 - 200 Nm shaft diameter from 6 - 32 mm
