Linear bearings, sometimes called track runner bearings, are part of a system suitable for use in precision linear motion applications, such as in printing machines and computer numerical control (CNC) equipment. Other system components include glide shafts, support rails, and glide blocks.A mounted linear bearing from Grainger, such as a linear pillow block bearing or flange bearing, can offset torsional misalignment and provide extra support. Choose linear motion bearings from single-flange and double-flange options. These bearings feature numerous holes that can allow you to add many accessories and brakes.


Thomson offers the world's largest selection of state-of-the-art linear bearings. Choose from several families of inch or metric linear bearings and accessories to meet your specific design needs, including our Super Smart Ball Bushings, which offer load capacities up to 7760 lb. When used with RoundRail linear guides, the inherent self-aligning-in-all-directions design of these linear bearings allows for ultra-smooth travel when mounted to wider-toleranced prepared surfaces. When used with Thomson 60 Case® shafting, our linear bearings last up to 50% longer than conventional bearings.
