Updated May 2019 || Physical values such as torque, torsional rigidity, spring stiffness, moment of inertia, imbalance, and zero-backlash play a major role in coupling design. Here are a few facts to keep in mind when you design your motion system. 1. Torque (Nm) is the product of an acting force and the effective length […]

ServoClass® Couplings deliver high torsional stiffness
ServoClass® Couplings suit applications using ac and dc servomotors that need precise positioning and the ability to handle high reverse loads. These couplings have zero-backlash and low hysteresis. Three new sizes have been added to the ServoClass coupling line. They handle bore diameters from 0.875 in. (20 mm) to 1.378 in. (35 mm) and operating […]
How to Properly Choose Servo Couplings
R+W Coupling Technology recently proposed a system on how to properly select your servo couplings. They state that servo systems require mechanical components with high torsional stiffness in order to perform properly in applications requiring rapid acceleration and deceleration of high inertia loads. Flexible couplings usually have the lowest torsional stiffness of any component in […]
High Torque Servo Couplings
Heavy duty torque ratings and high strength conical clamping hubs make BK3 couplings the choice for high torque servo gearboxes. Manufactured with a double-walled stainless steel bellows to absorb parallel, angular and axial shaft misalignment, the BK3 has an extremely high torsional stiffness to complement its relatively very low moment of inertia – allowing it […]
