BKL | Metal Bellows Coupling

With Clamping Hubs

The BKL coupling is designed with a single ISO 4762 radial clamping screw per hub.
This is an economically priced, easy mount coupling with a low moment inertia rating. It has a wide operating temperature range from -30 to 100 °C
There is absolutely no backlash due to the frictional clamp type connection. These couplings are maintenance-free for life, if the technical ratings are not exceeded.
The bellows are made of highly flexible high-grade
 stainless steel (See table for hub materials) while the hubs are aluminum. The BKL operates at speeds up to 10,000 rpm, in excess of 10,000 available with a finely balanced version. Custom designs with varied tolerances, keyways, 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.
