Original Press Release:
New Series Of 0.5, 0.8 & 1 Module Acetal Spur Gears from Sterling Instrument Feature Fairloc® Integral Hub Fastener
New Hyde Park, New York - A new series of precision 0.5, 0.8 and 1 Module acetal spur gears manufactured by Sterling Instrument (an ISO 9001 manufacturer) are produced to ISO Class 7 specs with 303 Stainless Steel hubs. They feature the Fairloc® integral hub fastener. These 20° pressure angle metric gears are identified as the S1VZ05M, S1VZ08M and S1VZ10M Series. Fairloc® is a patented integral hub fastener which eliminates marred shafts. 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 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. They are stocked in 5 mm face widths and are designed to fit shafts that are 5 or 8 mm in diameter. They are stocked in a range of sizes from 15 to 95 mm in diameter and from 15 through 186 teeth. Gears with 10 mm bores are stocked hubless, without the Fairloc® hubs.
