A series of shaft collars manufactured by SDP/SI (ISO 9001 + AS9100 Registered) feature the Fairloc® integral hub design and incorporates a built-in bearing shim spacer. These collars are manufactured in brass and stainless steel. The brass collars are identified as the S25FB9-... inch series and S25FBMPC... metric series. The stainless steel series collars are identified as S25FY9-... inch series and S25FY9MPC... metric series. They are designed to fit shafts that are .12" to 3/4" (3 to 20 mm) in diameter. Their O.D's range from .433" to 1.496" (11 to 38 mm) in diameter.

Fairloc® is an integral hub fastener. The Fairloc® hub design permits frequent phase adjustment, timing and position adjustment while adding positive metal-to-metal fastening strength along both hub sections. The Fairloc® integral hub fastener consists of two slots that are machined into the hub, one 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 eliminating any misalignment. The screw can be tightened and released repeatedly without marring the shaft or affecting its torque-transmitting abilities.
