Bellows coupling with 22 mm length & 12 mm diameter, bronze bellows

Bellows coupling in a ultra-compact design with a length of 22 mm and a diameter of 12 mm. The BKBS 1222 differs from its sister, the BKBK 1222, in that it is fastened with a grub screw and has a a little higher weight of approx. 8 grams and a a little lower moment of inertia of 1.8 gmm2. The other values are the same. The non-magnetic bellows made of bronze should be emphasized, the hubs are made of nickel-plated brass. One possible application is, e.g., the slip ring unit of an electric motor.
