Zero-Max SC020 ServoClass Double Flex Coupling Size 20 Inside Diameter 8mm-1 4"

Description:

The Zero-Max SC020 ServoClass double flex coupling (Size 20) is used in precision motion control systems to connect rotating shafts and transmit torque with high accuracy and zero backlash. Commonly installed in CNC machines, robotics, packaging equipment, and automated assembly systems, this coupling provides high torsional stiffness while accommodating shaft misalignment. Maintenance teams and system integrators use this coupling for system assembly, motion control upgrades, and replacement of worn or misaligned shaft connections.

Applications:

The Zero-Max SC020 servo coupling is widely used in industrial automation environments requiring precise torque transmission and shaft alignment. It is commonly found in servo-driven systems, CNC machining centers, packaging lines, printing equipment, and automated production machinery where repeatable positioning, high-speed operation, and mechanical reliability are critical to maintaining system performance.
