Zero-Max Model 6-30

Description:

The Zero-Max Model 6-30 is a composite disc (CD) flexible shaft coupling designed for precision motion control applications. It provides zero-backlash torque transmission, making it ideal for servo-driven systems where accuracy and repeatability are critical. The coupling uses a composite disc pack to transmit torque while accommodating misalignment, offering high torsional stiffness with flexibility and long service life.

Applications:

The Zero-Max 6-30 coupling is used in servo motors, packaging machinery, printing equipment, CNC machines, and automation systems. The coupling is commonly installed in high-speed and reversing applications where precise positioning and smooth torque transfer are required.
