Bellows coupling BKBS 1222 with 22mm lenght and diameter of 22mm
Bellows coupling in a very small 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 slightly higher weight of approx. 8 g and a slightly lower moment of inertia of 1.8 gmm2. The other values are the same. The non-magnetic bellows made of bronze should be noted, the hubs are made of nickel-plated brass. One possible application is, for example, the slip ring unit of an electric motor.
