Neo-Flex Couplings Feature Torsional Vibration Isolation


A new series of metric Neo-Flex couplings from Advanced Antivibration Components (AAC) feature excellent torsional vibration isolation plus shaft-to-shaft insulation. The center of these couplings, identified as the V50FSR-... (inch) and V50FSRM... (metric) for the Short Series, and V5DFLR-...(inch) and V5DFLRM (metric) for the Long Series, are made from 73 durometer molded neoprene along with 303 stainless steel hubs.
They are featured at the AAC eStore where you can order online, request a quote, download CAD models, check stock plus view catalog and technical pages.

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.
