Guide wheels. (New Products).

BISHOP-WISECARVER CORP., PITTSBURG, CALIF. DualVee guide wheels are available in two new sizes, size 0 and size 4XXL, respectively larger and smaller than the previously available sizes, WI through W4. Size 0 has an outside diameter of 0.58 in. and a working radial load capacity of 62 lbs., while size 4XXL has an outside diameter of 2.97 in. and a working radial load capacity of 1,620 lbs. The guide wheels are constructed of elements manufactured from 52100 bearing--grade steel. Hardened to Rockwell 60, the balls and raceways are protected from the ingress of debris by a pair of nitrile rubber seals, and a retainer maintains ball separation. The precision raceways are ground directly into the inner and outer race of the guide wheel to maximize stiffness and running accuracy. The new guide wheels are also available in stainless steel, providing for a higher level of corrosion resistance. The stainless steel version of the size 0 wheel is categorized as clean room compatible. It has load--bearing elements made of 440C stainless steel and is lubricated for life with a specially formulated PTFE Krytox grease. Shields and retainers are made of 304 stainless steel.
