Description:

Radial spherical plain bearings are available with different sliding contact surface combinations, i.e. the sliding surfaces of inner and outer rings are made from different materials. There are two main groups： spherical plain bearings requiring maintenance(steel-on-steel) and maintenance-free spherical plain bearings.
Maintenance-free spherical plain bearing sliding contact surfaces have four groups: steel-on-PTFE composite material, teel-on-PTFE fabric, steel-on-copper alloy and steel-on- PTFE plastic. Dynamic load support capability of steel-on-PTFE fabric spherical plain bearings is higher than that of steel-on-PTFE composite material. They have very low friction and can be operated without maintenance. They are used for applications where long bearing lives are required without maintenance, or where operating conditions, such as inadequate lubrication or the absence of lubrication make the use of steel-on-steel bearing inadvisable.
Outer ring in carbon steel, inner ring in carbon chrome steel with PTFE composite material on sliding surface.Harden treatment, sliding surface plated with hard chrome.
