RK series couplings are with very bigtorsional stiffness, almost rigid type. Applied in the drive of hydraulic pump andother equipment with effective moment of inertia. Also running under thelimited speed to avoid the hazardous resonance.

- Compactand strong structure, light weight, reliable running and long life.

- Verybig torsional stiffness, running under the limited speed to avoid the hazardousresonance.

- Ambienttemperature: -40-150℃
- Oilresistant

- Axial force-free

- ZeroMaintenance
