Bellows coupling: 12 mm diameter, 22 mm long, clamping hub

The BKBK 1222 is a bellows coupling with bronze bellows. It’s characterized by its ultra-compact design: only 22 mm long and 12 mm in diameter. The difference to the BKBS with screw hub are the clamping hubs and a particularly low weight of only 4 grams as well as a a little higher moment of inertia of 2.5 gmm2. The other data and parameters are the same. The bronze bellows is non-magnetic, the flange is made of nickel-plated brass. A classic area of application is slip ring units in electric motors, e.g..
