Design: With a single ISO 4762 radial clamping screw per hub. Self opening clamp system optional: Loosening the clamping screw applies force to the pin, which will force the clamp into the open position for easy mounting and dismounting. Temperature range: -30 to +120° C (3.6 F to 270) Backlash: Absolutely backlash-free Coupling. Service life: R+W couplings are maintenance-free and have an infinite life if the technical ratings are not exceeded. Fit tolerance: On the hub/shaft connection 0.01 to 0.05 mm. Material: Bellows are made of flexible, high-grade stainless steel. The hubs are made from aluminium. Non-standard application: Custom designs with varied tolerances, keyways, non-standard material and bellows are available upon request. Technical Data: rated torque from 15 - 500 Nm shaft diameter from 4 - 62 mm speeds up to 10,000 rpm, in excess of 10,000 with a finely balanced version.
