R+W BKS Series Reduces Inertia, Saves Space
May 20, 2011—The newly developed BKS series of stainless steel, welded bellows couplings from R+W are up to 1/3 shorter in length, reducing moment of inertia and saving space. Manufactured in Germany, the BKS makes use of 1.4301 (304) stainless steel hubs, precision machined to a high level of concentricity. Laser welded while mounted onto a common shaft to guarantee straightness, the couplings compensate for shaft misalignment and precisely transmit motion with zero backlash. Allowable temperatures range from -40 to +300 degrees C. The BKS coupling is available in 6 different sizes, with torque ratings from 15 to 500 Nm and English or metric bores from 12 to 75 mm.

Over the past 25+ years R+W has developed into a world leader in precision shaft couplings for torsional rigidity, vibration damping, and overload protection. Whether for micro motors or 10 megawatt drives, R+W couplings are customizable for most applications, while many standard models ship from stock. Configurable CAD models are available in a large number of file formats at www.rw-america.com ...Read more Or visit www.rw-america.com
