Diaphragm Coupling

Diaphragm couplings ensure reliable, backlash-free torque transmission in demanding drive systems – even at extremely high speeds and elevated temperatures.

Our couplings are custom-engineered to meet specific customer requirements. The flexible diaphragm geometry enables uniform load distribution and efficiently compensates for axial, radial, and angular misalignments. We also implement project-specific solutions for special dimensions or attachment components.

With our proven engineering expertise and precise manufacturing, we ensure long service life and minimal downtime in your system.

Your advantage:

• High power density and temperature resistance
• Maintenance-free operation thanks to wear-free diaphragm design
• Compensates for significant shaft misalignments while maintaining high torsional stiffness
• Low mass and moment of inertia for dynamic systems
• Design according to API 671 for maximum industrial safety standards
• Custom adaptation to machine and process interfaces

Applications and industries
