Zero Max 6A37C Clamp Hub Coupling 22mm ID, 3.75" OD,8000 RPM Max,3200 In-Lbs Max

Description:

The Zero-Max 6A37C clamp hub coupling is used in mechanical power transmission systems to connect rotating shafts and transmit torque with high precision and zero backlash. Commonly installed in CNC machines, packaging equipment, printing systems, and industrial automation machinery, this coupling provides high torsional stiffness while accommodating minor 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 6A37C coupling is widely used in industrial environments requiring precise torque transmission and shaft alignment. It is commonly found in servo-driven systems, machine tools, packaging lines, printing equipment, and automated production machinery where consistent performance, durability, and reliability are critical to maintaining system efficiency.
