Spherical Plain Bearing High Strength Car Industrial Bearing GEBJ8C

• Kinds of Spherical Plain Bearings

1.Spherical plain bearings requiring maintenance(steel-on-steel): It have hardened sliding contact surface on both rings. The surfaces are treated with molybdenum disulphide and phosphated. It has characteristics of wear-resistance and wear-corrosion. 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.

2. Maintenance-free spherical plain bearings: It have three groups: steel-on-PTFE composite material, steel-on-PTFE fabric and steel-on-copper alloy. 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 bearings inadvisable.

• Service Life

The service life of a GEGZ series plain shaft bearing operated under mixed or dry friction conditions is determined by the increase in bearing clearance or bearing friction caused by progressive wear of the sliding surfaces, plastic deformation of the sliding material or fatigue of the sliding surface. Depending on the application, the permissible wear or permissible increase in friction will be different. This means that under the same operationg conditions the service life which can be obtained in practice will be different.

The service life of a GEGZ series plain shaft bearing is the number of oscillating movements, or the number of operating hours which the bearing will service before a defined increase in bearing clearance or a defined increase in friction is reached.

The effective service life is that life which will be attained by a given spherical plain bearing under actual operating conditions. It is determined by the magnitude and type of load, but also by several other factors, such as contamination, corrosion, high-frequency load and movement cycles, shock etc. Some of these factors are impossible to determine or can only be determined with difficulty.
