Zero-Max SC040R-036-036 ServoClass Double Flex Coupling

Description:

The Zero-Max SC040R-036-036 is a ServoClass® double flex servo coupling designed for high-performance motion control systems. It provides zero-backlash torque transmission with high torsional stiffness, ensuring precise positioning and repeatability. The double flex disc design allows compensation for angular, parallel, and axial misalignment while maintaining smooth operation and minimal vibration. These couplings are engineered with low inertia for high-speed applications and are commonly used in servo-driven equipment.

Applications:

The Zero-Max SC040R 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 accurate motion transfer, low backlash, and reliability are critical.
