High-Speed Cruved Tooth Couplings
RENK’s High-Speed Cruved Tooth Couplings are engineered for high and very high-speed applications. The MCN and MCF series use a single contoured diaphragm to transmit torque. These couplings are maintenance-free and offer high flexibility to compensate for angular, axial, and parallel misalignments.

Key advantages include:
- High temperature resistance
- Extremely high radial stiffness
- Low restoring forces and bending moments
- Very high torque and speed capability
- Extended lifespan and utmost dependability
These features make RENK's diaphragm couplings ideal for high-speed, high-performance applications requiring precision and durability.
