Spherical Bearing Lubrication

High rigidity Model PB

With this model, a special copper alloy with high conformability is inserted between the steel outer ring and the spherical inner ring in which only the spherical area is hard chrome plated. This structure makes this model a highly rigid Spherical Plain Bearing with high corrosion resistance and high wear resistance.
