R+W- BK Series, metal bellows drive couplings

Bellows Coupling series BK are rated for torque levels from 15 – 10,000 Nm depending on the model. Shaft sizes possible range from 8-190mm.

The BK series couplings are maintenance-free and have an infinite service life, if the tolerances are not exceeded.

The bellows are made of flexible, high-grade stainless steel. The hubs are made from aluminium.

The couplings provide completely backlash free power transfer.
