Spherical Plain Bearings Requiring Maintenance

Spherical Plain Bearings Requiring Maintenance (Lubrication)

Spherical Plain Bearings requiring maintenance (steel-on-steel) have hardened sliding contact surfaces on both rings. The surfaces are typically treated with molybdenum disulphide and phosphate (this provides added wear resistance and wear-corrosion). However, Spherical Plain Bearings with this sliding contact surface combination require regular relubrication. The high strength of the sliding contact surfaces makes these bearings especially suitable for bearing arrangements where heavy loads of alternating direction, shock loads, or heavy static loads have to be accommodated.
