A new series of metric Neo-Flex couplings from Advanced Antivibration Components (AAC) is claimed to feature excellent torsional vibration isolation and shaft-to-shaft insulation.

The centre of these couplings, identified as the V50FSR (inch) and the V50FSRM (metric) for the Short Series and V5DFLR (inch) and V5DFLRM (metric) for the Long Series, is made from 73 durometer-moulded neoprene along with 303 stainless-steel hubs.

They are featured at the AAC e-store where customers can order online, request a quote, download computer-aided-design models, check stock and view catalogue and technical pages.

They are stocked in two hub styles, conventional pin-type hubs that use a set screw for fastening and a Fairloc version.

Fairloc is a patented integral hub fastener that 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 and the other angularly, to create a transverse wedge that 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 that 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 centre sections.

The ribbed style features an angular misalignment of 5 degrees or 15 degrees (long style) and a parallel offset of 0.25mm (short style) or 0.38mm (long style).

The smooth style features an angular misalignment of 1 degree (short style) or 8 degrees (long style) and a parallel offset of 0.13mm (short style) or 0.25mm (long style).

They are designed to fit 3mm to 6mm metric shafts or 0.1200in, 1/8in, 3/16in and 1/4in shafts.

AAC stocks a range of anti-vibration and shock isolation products including: stud- and nut-type mounts, base-plate-fastened mounts, wheels, levelling and foot mounts, suspension mounts, spring, steel mesh and cable mounts, bumpers, shock absorbers and channel mounts, bushings and grommets, pads and tapes and couplings.

These products are stocked in different materials including: rubber, neoprene, urethane, sorbothane, stainless-steel mesh and springs.

Many are suitable for use in extreme environmental conditions.

The company offers a complete selection of silicone-gel floor mounts, pads and sheets and paste-type thermal gels.
