Miniature instrument bearings are assembled with matching LinearRace(TM) shaft, guaranteeing a fit of 0.0001 to 0.0003 inch clearance. Smoothness is assured by finishing the working surfaces of the bearings and LinearRace shafts to better than 4 microinches. Precise positioning is enhanced with the virtual elimination of stick/slip by the bearings' low coefficient of dynamic friction. Bearings are available in 1/8, 3/16, and 1/4 inch bore sizes, and their stainless steel and brass construction makes them highly corrosion-resistant. The bearings can be used where lubricants cannot be tolerated, and applications include those requiring extremely precise and smooth motion
