R+W's Servo Couplings

R+W's Servo Couplings

The trend in industry to process more material faster and more efficiently calls for a high-torque, high-misalignment, low-inertia servo coupling, with minimal compromise to torsional stiffness. Stainless-steel bellows couplings have the highest torsional stiffness of commercially available flexible couplings, making them the best choice for aggressive servo-driven applications. But in cases where the two shafts to be connected are mounted to different bearing surfaces, it can be difficult to maintain the precise alignment tolerances normally required.

Utilizing a special, high-stiffness bellows and new, high-strength connection method, R+W's BKZ handles an average of 2.6 times the traditional torque rating at a given outside diameter, and an average of 2.9 times more lateral misalignment, opening up the benefits of precision bellows couplings to a whole new segment of machine design and servo motion control.

Accepting bore diameters ranging from 15 to 60 mm and torque ratings from 20 to 1,000Nm, the BKZ range is available in four sizes, with a variety of materials, finishes and the optional self-opening clamp system.
