Plain bearings are widely used in construction machinery. Introduction and classification of spherical plain bearings Spherical sliding bearings, the basic type is composed of inner and outer rings with spherical sliding spherical contact surfaces. Depending on its structure and type, it can bear radial load, axial load, or combined radial and axial loads at the same time. Because the spherical sliding contact area of the spherical plain bearing is large, the inclination angle is large, and because most of the spherical plain bearings adopt special processing methods, such as surface phosphating, zinc plating, chrome plating or outer sliding surface lining, padding, spraying, etc. Therefore, it has a large load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self-alignment, good lubrication or self-lubricating without lubrication and dirt pollution, and can work normally even if the installation is misplaced. Therefore, spherical plain bearings are widely used for low-speed oscillating motion, tilting motion and rotational motion.

RLB spherical plain bearing for enginering machinery can help machine more efficiently run.
