R+W Bellows Coupling - Series BK

HIGH PRECISION, ZERO BACKLASH, AND TORSIONALLY STIFF: METAL BELLOWS COUPLINGS FROM R+W

High precision bellows couplings are used wherever positional accuracy and dynamic motion are in demand. This can be in medical devices, test rigs, wind power turbines, servo axes in machine tools, wood processing machinery, packaging machinery and many more high performance equipment types.

Bellows couplings are especially suitable for direct connection between two coaxial shafts. The metal bellows defines the characteristics of the coupling and compensates lateral, axial and angular shaft misalignment with low restoring forces. Backlash-free, torsionally rigid metal bellows guarantee precise positioning of the driven load, and can be used in highly dynamic cyclic duty applications, as well as at extremely high rotational speeds - up to 200,000 rpm depending on the model.
