The SW038-series of miniature crossed roller bearing guided manual linear slides offer travels of up to 7.8", a high payload capacity of up to 789 lbs, plus very good smoothness, very low friction and a very good straightness and flatness accuracy
Parker’s SW Series of The crossed roller slide bearing system is composed of two rows of rollers. Each roller is alternately crossed at 90° with the next and captured in “V” grooves, located on the base and top. Since rollers provide a larger (line) contact surface than ball bearings, a crossed roller slide has higher load carrying capability than a ball slide of comparable size.
The SW Series is our smallest crossed roller slide. The SW038 offers excellent precision, smooth motion, and a long life in a package that is only 38 mm wide.
