NB Corporation of America (Hanover Park, IL) released TOPBALL® slide products that self-align. The floating wiper seal makes unrestricted self-alignment possible. A floating load plate adjusts clearance, and tolerances are achieved by grinding the raceways and load plates. Applications include automation equipment, machinery, and optical and measuring instruments. They also are suited for new designs and are interchangeable for retrofitting. The slide products are available as total systems or as individual components such as slide bushings, housings, slide shafts, and supports in metric or inch.
