New Hyde Park, New York - SDP/SI offers the patented FairlocŪ integral hub fastener system for fastening rotating components such as: gears, pulleys, couplings, collars, ujounts, stc, to shafts.
FairlocŪ is a patented integral hub fastener which eliminates marred shafts. The choice of FairlocŪ hubs permits frequent phase adjustment, timing and position adjustment while adding positive metal-to-metal fastening strength along both hub sections. The FairlocŪ 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. A special FairlocŪ visual index can be viewed here.
