New Hyde Park, NY -- Precision gear & dial hubs from Sterling Instrument (ISO AS9100 Registered Manufacturer) are designed to fit gears or dials and eliminate keys or splines. Identified as the S2F06Y-.... Series, these 303 stainless steel hubs feature our patented Fairloc® design. The compact self-contained design is perfect when hub O.D. is limited.

Fairloc® 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 and the other angularly, to create a transverse wedge that remains attached to the hub. 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.
