Why Choose Ringfeder’s RfN 7515 Series?

Designed with 3 locking assembly parts with reduced stress in the locking joint itself. High precision to transmit maximum torque and axial force with special requirements on concentricity, withstand bending moment, reduce contact surface pressure between the equipment shaft and the hollow shaft (hub). Withstand bending load and radial load - combined load.

Locking Assemblies RfN 7515 are widely used in cranes, gearboxes, flywheels, fans. A slight axial force occurs between the locking joint and the shaft, optimizing the transmission of bending loads.
