Medium-precision, light duty aluminium rings are quiet in operation

20 June 2011

If you are in the market for medium precision, light duty motion systems, then HepcoMotion's new ALR aluminium rings will appeal to those also seeking quiet operation. Bishop-Wisecarver DualVee polymer over-moulded guide wheels with integral studs make a significant contribution to the ring’s virtually noiseless operation. They run exceptionally smoothly with little friction or wear on the ring vees. All metal parts are stainless steel and the shielded wheel bearings are lubricated for life.

The ALR rings themselves are machined from high strength aluminium alloy and are anodised to a specification which gives a good combination of durability and corrosion resistance. The finish is attractive too and provides an ideal running surface for the DualVee polymer wheels. ALR rings can be supplied with a special durable finish, which the company claims is more corrosion resistant than stainless steel, and which is also approved by the US Department of Agriculture for food use.

Rings are available in four standard diameters from 148mm to 300mm and these are compatible with the size 2 DualVee wheels. For smaller, lighter applications, sizes 1 and 0 DualVee wheels can also be specified. 

Special rings can also be supplied, including rings with different diameters and thicknesses, rings with internal vees, gear cut rings and rings machined in the form of self aligning timing belt pulleys.
