PB22 bearing has a steel-on-bronze sliding contact. The steel inner ring contacts the bronze surface of the outer ring. The steel-on-bronze sliding contact makes this bearing highly wear-resistant, providing low friction. However, the load capacity is slightly lower compared to spherical plain bearings with steel-on-steel sliding contacts. This bearing needs regular maintenance. Proper lubrication is required to reduce friction and prevent fouling and corrosion.
Applications: Hydraulic Cranes, Haul Trucks, Wind Turbines, Satellite Antennas, Forklift Trucks, Extractors, Front End Loaders, Overhead Carriers, Chain Conveyors, Log Skidders, and etc.
