Aluminium rings for light loads and light duty

The new ALR aluminium rings are a cost effective choice for medium precision, lightly loaded applications. This product will prove particularly appealing to those for whom quiet operation is an important criterion. Theatre and film animation are typical applications. 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 an excellent combination of durability and corrosion resistance. The finish is attractive too and provides an ideal running surface for the DualVee polymer wheels. Another advantage of course is that aluminium provides designers with a non-magnetic choice. ALR rings can be supplied with a special finish, which is more corrosion resistant than stainless steel and is very durable. And, it is approved by the US Department of Agriculture for food use. Rings are available in 4 standard sizes from 148mm to 300mm in diameter 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 economically. The choice includes different diameters and thicknesses, rings with internal vees, gear cut rings and rings machined in the form of self aligning timing belt pulleys.
