Three different types of bearings are offered. Steel concave rollers riding on chrome-plated steel rails provide excellent positioning accuracy even in applications that require long travel. A plastic coated needle bearing assembly offers the highest possible speeds. Finally, plastic bearings running on aluminum rails provide the ultimate in durability in tough push-pull applications. The steel bearings are supplied with lifetime lubrication while both types of plastic bearings require no lubrication at all.
