Zero-Max SC030R-030-021 Servo Class Double Flex Servo Coupling

The Zero-Max SC030R-030-021 ServoClass double flex servo coupling provides zero-backlash torque transmission for precision motion control systems. Its double flex disc design accommodates angular (~1°), parallel (~0.007"), and axial misalignment while delivering high torsional stiffness and low inertia, supporting speeds up to 10,000 RPM and a torque capacity of ~44 in-lbs (5 Nm). With a size of 30 and bore range ~0.1875–0.625 in (variant dependent) and shaft-to-shaft clamp mounting, this coupling is commonly installed between servo motors and loads or gearboxes in CNC machines, robotics, packaging equipment, and automation systems to minimize backlash and vibration and improve repeatability. Part number SC030R-030-021, from Zero-Max, belongs to the ServoClass double flex family.
