Compact servo coupling

Compact servo coupling

Series BK8 couplings are for mounting to flange-output servo gearheads — which are used for high stiffness and compact design.

Features & benefits

  • BK8 coupling now allows for compact, flexible interface between gearheads and driven components, protecting bearings and making alignment simpler

  • Stainless steel bellows for torsional stiffness also compensate for small misalignment between mating components; torque ratings from 15 to 1,500 Nm and (for special applications) up to 10,000 Nm

  • Traditional clamping hub or variety of coupling output hubs, including expanding shafts and tapered conical clamping hubs
