Thrust Loading - Steel, PTFE-Fabric, PTFE-Plastic Materials
Spherical plain thrust bearings have sliding contact surfaces in the shaft and housing washers which are arranged at an angle to the bearing axis. They are primarily intended for axial loads although they can accommodate combined loads to a certain extent. spherical plain thrust bearings are available with different sliding contact surface combinations, i.e. the sliding surfaces of shaft and housing washers are made from different materials. There are two main groups:

•Steel-on-steel spherical plain thrust bearings
•Maintenance-free spherical plain thrust bearings
Steel-On-Steel Spherical Plain Thrust Bearings
The steel-on-steel spherical plain thrust bearings supplied by CHH are made of carbon chromium steel and are hardened and phosphated, the shaft and housing washers sliding contact surface are treated with molybdenum disulphide, it has characteristics of wear-resistance and wear-corrosion. Bearings with this sliding contact surface combination require regular relubrication. To facilitate efficient lubrication, housing washer have an annular groove and a lubrication hole. The high wear resistance of the sliding 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.

Maintenance-Free Spherical Plain Thrust Bearings
The maintenance-free spherical plain thrust bearings supplied by CHH have sliding contact surface combinations steel-on-PTFE fabric and steel-on-PTFE plastic, they have very low friction and can be operated without maintenance, any lubrication of the sliding contact surfaces will shorten bearing life. 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. The maintenance-free bearings are primarily intended for applications where loads are heavy and have a constant direction.

CHH angular contact spherical plain bearings products are broken down into the following series:

•GX-S Series – Steel-on-Steel, Thrust Bearing, metric dimensions
•GX-T Series – Steel-on-PTFE-Fabric, Thrust Bearing, metric dimensions
•GX-N Series – Steel-on-PTFE-Plastic, Thrust Bearing, metric dimensions
