BKS Series Welded Bellows Couplings from R+W

By Leslie Langnau | May 19, 2011

R+W America’s BKS series of stainless steel, welded bellows couplings 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°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 75mm.
