New Precision Gear & Dial Hubs from SI Designed To Fit Hubs with Limited Hub O.D., Eliminates Keys

Mon, 07/02/2012 - 1:49pm

LISTED UNDER:

A new series of precision gear & dial hubs from Sterling Instrument are designed to fit gears or dials, plus eliminate keys or splines. Identified as the S2F06Y-Series, they are made of 303 stainless steel. Hub mounting lengths range from .062” to .187”. Their bore diameters range from .0900” to .2498”. These Fairloc® hubs can be ordered pre-assembled to gears or dials.

The choice of Fairloc® hubs 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 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.
