    Products   Fairloc® Explaination Video

Fairloc® is the better way to fasten rotating components.

Fairloc® solves phasing, timing, positioning and frequent removal problems.

  • Easy Adjustment Fairloc® replaces set screws and clamps; components can be repositioned with a single hex key adjustment.
  • Will not Mar Shaft
  • Outstanding Reliability
  • Compact, Self-Contained Design When available space or access is limited Fairloc's® small hub envelope is a distinct advantage.
  • Full Use of the Bore Gives maximum support to the component, reduces wobble or misalignment.
  • Superior to Other Fasteners in High-Torque Applications

Here’s how it Works
Two slots are machined into the hub; one oriented radially, the other angularly, to create 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 passes 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.
