Bellows couplings BKA for FOI

A stainless steel bellow provides compensation for both misaligment or axial displacement between the two shafts. The couplings are particularly suitable for the rotationally stiff driving of high resolution angle transducers.

For the BKA coupling each of the shafts are attached with hexagon socket set screws. The hubs are in aluminium. The bellow material is stainless steel. The service life of the couplings (number of turns or changes of load) depends on the following factors and can therefore only be reliably determined in practical tests: Torque and moment of inertia of the driven transducer, actual parallel and/or angular offset, axial play in the driven shafts and the ambient temperature must be taken into consideration.
