3. Applications of Ringfeder Locking Assemblies RfN 7004

The flange is reinforced at the limit point to prevent bending and lifting of the ring during installation. The Ringfeder locking assemblies RfN 7004 are designed to reduce the connection pressure between the shaft and hub effectively, withstand high torque, and allow for easy assembly and disassembly. This self-centering locking assembly provides excellent concentricity. It is suitable for connecting motor-gearbox-shaft assemblies with other drive components.
