The Fairloc S2F06Y-.... Series of precision gear and dial hubs are designed to fit hubs with limited hub OD and eliminate keys or splines. The hubs are made of 303 stainless steel, come in mounting lengths from 0.062 to 0.187 in., bore diameters from 0.0900 to 0.2498 in., and can be ordered preassembled to gears or dials.

The hubs permit frequent phase adjustment, timing, and position adjustment while adding positive metal-to-metal fastening strength along both hub sections.

The hub fastener consists of two slots machined into the hub, one radially and 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 torquetransmitting abilities.
