ZERO-MAX SC050 SERVOCLASS COUPLING, 3 4" ID TO 1" ID #252571

Description:

The Zero-Max SC050 ServoClass coupling is a high-precision flexible shaft coupling designed for servo motor applications requiring zero backlash and high torsional stiffness. It uses a disc-style flex element to transmit torque while compensating for shaft misalignment. The SC050 series is engineered for smooth motion, low inertia, and repeatable positioning, making it suitable for high-performance automation systems.

Applications:

The Zero-Max SC050 coupling is used in servo motors, CNC machines, robotics, packaging equipment, and automated production systems. The Zero-Max coupling is commonly installed in motor-to-load or motor-to-gearbox connections where precise motion transfer and minimal backlash are required.
