Original Press Release:

New Series of Stainless Steel Gears from QTC Feature the Fairloc® Integral Fastening System

Garden City Park. New York -- A new series of Module 0.5, 0.8, and 1.0 spur gears from Quality Transmission Components feature the patented Fairloc® integral hub fastening system which eliminates marred shafts. These 20° pressure angle precision gears conform to JIS B 1702 Grade 4 standards. These 303 stainless steel gears are identified as the SUSL Series. The Fairloc® integral hub fastener is the ideal choice where phase adjustment, timing, position adjustment and frequent removal of the component are factors in the specific application. In addition, Fairloc® offers full component support along the entire hub section. These very cost-effective gears are compact, self-contained and offer a small gear hub envelope.

These gears are designed to fit shafts ranging from 4 mm to 10 mm in diameter. They are stocked with face widths ranging from 5 to 8 mm. Their sizes range from 14 to 120 teeth.

The Fairloc® system consists of two slots that are machined into the hub, one orientated 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 socket head cap 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.

Complete technical specifications are provided in Bulletin Q410, which is available to users of metric gears free upon request from Quality Transmission Components, 25 Railroad Avenue, Garden City Park, NY 11040-5016. Phone: Phone: 516-437-6700. Fax: 516-328-0539
