Zero-Max SC050R-001-023 Size 50 Coupling .375" w KW x 1" w KW

Description:

The Zero-Max SC050R-001-023 is a ServoClass double flex disc coupling designed for precision motion control applications. It provides zero-backlash torque transmission while accommodating angular, parallel, and axial misalignment. The disc-pack design delivers high torsional stiffness and low inertia, making it ideal for servo systems requiring accurate positioning and repeatability. These couplings are engineered to reduce reaction loads on bearings and extend system life.

Applications:

The Zero-Max SC050R coupling is used in servo motors, CNC machinery, robotics, packaging equipment, and automated production systems. The Zero-Max coupling is commonly installed in motor-to-gearbox or motor-to-load connections where precise motion transfer and minimal backlash are required.
