Featured Product from Stock Drive Products & Sterling Instrument - SDP/SI
For precise alignment and ease of use nothing surpasses the SDP/SI Fairloc® Hub Design. Shaft Collars manufactured by SDP/SI (ISO 9001 + AS9100 Registered) feature this unique hub design and include a built-in bearing shim spacer. These collars are precision machined in brass and stainless steel, are available in both inch and metric sizes, and available at our E-Store. Specify S25FB9-... inch and S25FBMPC... metric for brass, black oxide finish and S25FY9-... inch and S25FY9MPC... metric for 303 Stainless Steel. Designed to fit shafts that are .12" to 3/4" (3 to 20 mm) in diameter, O. D’s range from .433" to 1.496" (11 to 38 mm). Our engineers can help with custom options if needed.
What is Fairloc®?
Fairloc® is an integral hub fastener designed for critical rotating and power transmission components. The Fairloc® hub design permits frequent phase adjustment, timing and position adjustment while adding positive metal-to-metal fastening strength. 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 and motion. The screw can be tightened and released repeatedly without marring the shaft or affecting its torque-transmitting abilities making it cost effective in assembly and field maintenance.
