What is a Diaphragm Coupling?

A diaphragm coupling (also called disc coupling) uses flexible stainless steel discs to transmit torque while compensating for misalignment. This servo motor coupling offers:

• Zero backlash transmission
• High torsional rigidity
• Maintenance-free operation
• Long service life

Key Features

• High precision machining with excellent concentricity
• High torque transmission capacity
• Single or double diaphragm options
• Compact structure with stable operation
• Suitable for high-speed applications
• Easy installation and maintenance

This high precision coupling ensures consistent and reliable performance.
