May 30, 2007—The patented system offers several advantages including: built-in overload protection, full use of the bore, easy adjustment, compact self- contained design. With this FairlocŪ system, the shaft remains smooth. It is self-contained, so there is no additional inventory to keep in stock. The component can be easily adjusted and is fully supported.

Two slots are machined into the hub, one oriented radially, the other angularly, this creates a transverse wedge which remains attached to the solid portion of the hub on one side. The resultant cantilevered clamping section has a tapped hole to accept a cap screw which is passed through a clearance hole in the solid portion of the hub, and into a threaded hole in the transverse wedge section. As the screw is tightened, the cantilevered section clamps the shaft securely. The screw can be tightened and released repeatedly without marring the shaft or affecting its torque transmitting abilities.
