linear bearings

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.

Linear motion is the most basic of all motion. Linear ball bearings provide linear movement in one direction.
A roller bearing, carries a load by placing rolling balls or rollers between two bearing rings called races. These bearings are comprised of an outer ring and several rows of balls retained by cages. Roller bearings are manufactured in two styles: ball slides and roller slides.
