The BKM coupling is designed with a single ISO 4762 radial clamping screw per hub.
This is an easy mount coupling with a high torque and low moment inertia rating for its size. It's compact form makes it ideal for applications where space is limited. It has a wide operating temperature range from -30 to 100 degrees Celsius. There is absolutely no backlash due to the frictional clamp type connection. These couplings have an infinite lifespan and are maintenance-free if the technical ratings are not exceeded.
The bellows are made of highly flexible high-grade stainless steel (See table for hub materials). R+W's BKM is made to operate at speeds up to 10,000 rpm, in excess of 30,000 available with a finely balanced version. Custom designs with varied tolerances, key-ways, non-standard material, bellows and ATEX designs are available upon request.
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.
