Procurement Intelligence
The RfN 7012 is a Ringfeder locking assembly designed for secure hub-to-shaft connections without keyways. Installation requires the locking bush to be mounted between shaft and hub with radial screws creating an interference fit. Verify shaft and bore diameters match exactly (28mm × 55mm) before procurement to ensure proper clamping force.
Keyless shaft hub coupling
Before ordering — verify:
☐ Shaft diameter tolerance
