Zero-Max has introduced the new ServoClass-HSN Coupling to address noise and vibration issues that can be experienced in certain high-gain, high-speed stepper/servo motor applications. Featuring a highly saturated Nitrile rubber flex element, these couplings are specifically designed for maximum damping and performance. The zero-backlash design of the ServoClass-HSN also features an optimal torsional stiffness to provide low hysteresis and ensure repeatable, accurate positioning in applications requiring increased damping properties. Additional features include low inertia, high misalignment capacity, low reaction loads under misalignment, RoHS compliant corrosion-resistant fasteners and electrical isolation.
