Power Locks are keyless shaft-hub locking devices designed to transmit torque through frictional contact, eliminating the need for keyways, splines, or other traditional fastening methods. They provide a secure, backlash-free connection between the shaft and mounted components such as gears, pulleys, or sprockets.

Constructed from high-strength steel, Power Locks use tapered rings or wedge mechanisms that expand uniformly during tightening, creating a strong clamping force. This design ensures precise centering, high torque transmission, and resistance to axial and radial loads.

Power Locks are ideal for applications requiring frequent disassembly, precise alignment, or enhanced torque capacity. They are commonly used in heavy machinery, automation systems, and power transmission assemblies.

• Backlash-free
• Low moment of inertia
• Compensation of shaft misalignment
• Optional stainless steel
• Backlash-free
• Compensation of radial, axial and angular misalignment
• Backlash-free
• Maintenance free, no wear
• Optimal moment of inertia
• High torsional stiffness and misalignment compensation

• Alignment is quickly achieved by simply placing a straight edge across the outside diameter of the hubs. No special tools are needed, only a hexagon wrench for the locking of the taper bush.

• The RFC coupling compensates for axial, parallel & angular misalignments.

• The Inter-locking hubs act as an additional safeguard, through the flexible element fails, the drive will be maintained by the interaction of the jaws which are an integral part of the coupling hubs. The hubs are made of C.I.. Jaws are unmachined.

• The RFC coupling is compatible with leading makes of couplings. Elastomeric spider is of Nitrile rubber having shore hardness of 80⁰, suitable for temperatures Iron -40⁰C to +100⁰C.
