R+W Coupling Technology Bellows Coupling BKL Series

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.

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.
Hub materials see table.

Non-standard application:
Custom designs with varied tolerances, keyways, non-standard material and bellows are available upon request.
