PRODUCT ANNOUNCEMENT: METAL BELLOWS COUPLINGS: TORSIONALLY STIFF, BACKLASH FREE, AND FLEXIBLE

R+W BK series bellows couplings are characterized by their wide variety of mounting options, including clamping hubs, conical clamping bushings , expanding mandrels, and fully split clamping hubs, among others.  These backlash free and maintenance free flexible coupling products are also available in single position and multi-position “plug-in” versions.  Another newer version is available which can compensate for parallel shaft misalignment of up to 1mm. 

The continuous symmetry of the formed stainless steel bellows provides for highly accurate output rotation, even when subjected to any or all three of the types of shaft misalignment. The precision manufacturing process of mounting both hubs onto a common assembly mandrel, and bonding the bellows between them, guarantees concentricity between the hub bores, while ensuring no bending or crimping stress is placed on the bellows. The result is very smooth running and accurate transmission and measurement results, even at very high speeds.  The low moment of inertia and high torsional stiffness also make them very well suited to highly dynamic drive characteristics.

Couplings from the BK series are available in 16 body sizes corresponding to torque ratings ranging from 2 to 10,000 Nm and with bore diameters ranging up to 180mm.
