This Thomson Super Smart series closed type ball bushing bearing provides free linear movement on a hardened steel shaft. Ball bushing bearings are linear ball bearings that reduce friction for linear motion. The bearing’s outer sleeve and ball retainer are made of Delrin (polyoxymethylene) for strength and dimensional stability, and the balls are made of chrome steel for high load capacity and resistance to wear and corrosion. A self-alignment feature accommodates misalignment from installation imperfections, including housing bore out of roundness, without impairment of performance. The low coefficient of friction allows the use of smaller motors, belts, and gears compared to conventional linear bearings. The bearing has a maximum operating temperature of 185 degrees F (85 degrees C). This ball bushing bearing is shipped with a rust preventative oil, and is used in XY tables and other types of material handling equipment.

Plain bearings provide low-friction sliding contact for relative motion between parts of a machine. They are the simplest type of bearing, with no rolling elements, and there are three basic types of plain bearings: radial plain bearings (also called sleeve bearings or bushings) to support rotating or reciprocating shafts, thrust bearings (also called washers) to support axial loads on shafts, and linear bearings to support and guide the motion of parts in a straight line. Flanged sleeve bearings have a flange on one end to support axial loads. Spherical plain bearings are radial bearings that allow for angular misalignment of the shaft. Plain bearings are made from durable, low-friction materials such as sintered or cast bronze alloys, plastic, or a combination of a metal shell and a plastic bearing surface. They can be lubricated externally or by a lubricant embedded in the bearing material. Plain bearings are used in automobiles, construction and mining equipment, textile manufacturing equipment, and robotics, among others.
