New Series of 64 Neo-Flex Couplings From Sterling Instrument Feature Torsional Vibration Isolation
New Hyde Park, New York - A new series of 64 Inch and 64 Metric Neo-Flex couplings from Sterling Instrument (an ISO 9001 manufacturer) feature torsional vibration isolation plus shaft-to-shaft insulation. The center of the couplings, identified as the S50F and S50P Series, are made from 73 durometer molded Neoprene along with 303 Stainless Steel hubs.
They are stocked in two hub styles, conventional pin type hubs which use a set screw for fastening and a Fairloc® version. 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 with both ribbed and smooth style center sections. The ribbed style features an angular misalignment of 5° or 15° (long style) and a parallel offset of 0.25 mm (.010")(short style) or 0.38 mm (.015")(long style). The smooth style features an angular misalignment of 1° (short style) or 8° (long style) and a parallel offset of 0.13 mm (.005")(short style) or 0.25mm (.010")(long style). They are designed to fit 3 to 6 mm metric shafts or .1200, 1/8, 3/16 and 1/4 inch shafts.
