This VXB GEZ008ES spherical plain bearing is made of chrome steel and is unsealed. It has a 1/2" inside diameter, a 7/8" outside diameter, and a 7/16" depth. This spherical plain bearing has a wide race cross-section for applications that provide high misalignment adjustment. This bearings race and ball are made of chrome steel for durability and resistance to deformity under heavy loads. Lubrication grooves and holes in the race direct grease into the bearing. The bearing has an open configuration for lubrication in place and is intended for use in pivoting, high load bearing applications with little exposure to dirt, grime, debris, and other contaminants.
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.
