Spherical plain thrust bearing steel on steel. Treated with molybdenum disulphide mos2, regreasable. For use at axial loads.
Steel-on-Steel | Metric Series | High Axial Load Capacity | Relubricatable
GX…S / GE…AX / GXD…SA Thrust Spherical Plain Bearings are designed primarily to accommodate axial loads acting in one direction while allowing angular movement and misalignment between connected components.
These bearings can also accommodate combined axial and radial loads within specified operating limits, making them suitable for industrial machinery and mechanical assemblies subjected to substantial thrust loading.
Thrust spherical plain bearings consist of a shaft washer with a convex spherical sliding surface and a housing washer with a corresponding concave spherical sliding surface.
The spherical sliding contact geometry allows the bearing to accommodate angular misalignment while transmitting axial loads.
Steel-on-steel designs typically feature hardened bearing steel components with protective surface treatments.
GX…S and GE…AX bearings are generally maintenance-required designs, with lubrication provisions that facilitate grease replenishment during operation.
GXD…SA bearings represent a related steel-on-steel thrust spherical plain bearing design featuring a multi-groove lubrication system.
These bearings are suitable for mechanical applications requiring high axial load support, angular movement, and reliable lubrication.
Thrust spherical plain bearings are primarily designed to support axial loads acting in one direction.
Their spherical sliding contact surfaces provide load support for mechanical assemblies subjected to substantial thrust forces.
In addition to axial loads, thrust spherical plain bearings can accommodate limited radial loads.
However, axial loading must remain the dominant load component.
The permissible radial load depends on the bearing design and operating conditions.
GX…S, GE…AX, and GXD…SA steel-on-steel designs feature hardened steel sliding contact surfaces.
This construction provides load-carrying capability for suitable heavy-duty industrial applications.
The spherical sliding surfaces accommodate limited angular movement between the shaft washer and housing washer.
The permissible misalignment angle depends on the bearing dimensions and installation conditions.
Thrust spherical plain bearings generally consist of separable shaft and housing washers.
This allows the components to be installed separately in suitable mechanical assemblies.
Steel-on-steel thrust spherical plain bearings require appropriate lubrication.
Lubrication grooves and holes may be incorporated into the housing washer to facilitate grease distribution.
The GXD…SA design features a multi-groove lubrication arrangement intended to improve lubricant distribution across the sliding contact surfaces.
These bearing series are available in metric dimensions, providing options for various industrial machinery and equipment designs.

GX…S bearings are metric thrust spherical plain bearings featuring steel-on-steel sliding contact surfaces.
They are designed to accommodate axial loads acting in one direction and allow angular misalignment.
The bearings typically incorporate lubrication grooves and holes to facilitate periodic grease replenishment.
GE…AX bearings are another commonly used designation for steel-on-steel thrust spherical plain bearings.
Their shaft and housing washers feature matching spherical sliding surfaces.
These bearings are suitable for applications involving substantial axial loading and limited angular movement.
Certain GX…S and GE…AX models have corresponding dimensions, but individual specifications should be checked before interchange.
GXD…SA bearings feature a steel-on-steel sliding contact combination and are intended for demanding axial load applications.
A distinguishing feature of this design is its multi-groove lubrication system.
Lubrication holes and an annular groove in the housing washer allow lubricant to be supplied to the sliding contact surfaces.
This design can be considered for applications involving heavy axial loads and alternating loading conditions, subject to the specified bearing ratings.
Thrust spherical plain bearings can be considered for industrial applications requiring substantial axial load support and angular movement.
Typical application areas include:
Hydraulic Equipment
Selected hydraulic and mechanical actuator assemblies may require bearings capable of accommodating axial forces and angular misalignment.
Construction Machinery
Heavy construction equipment may incorporate thrust spherical plain bearings in suitable load-bearing and articulated mechanisms.
Industrial Lifting Equipment
Thrust spherical plain bearings can be considered for selected lifting and positioning mechanisms where axial loads are dominant.
Mining Machinery
Mining equipment often operates under demanding mechanical conditions involving heavy loads and vibration.
Agricultural Machinery
Selected agricultural equipment mechanisms may require axial load support and angular movement.
Industrial Mechanical Assemblies
Thrust spherical plain bearings can be used in appropriate mechanical arrangements requiring axial load transmission and angular misalignment accommodation.
Actual suitability must be evaluated according to the bearing arrangement, applied loads, lubrication conditions, and operating environment.
Steel-on-steel thrust spherical plain bearings require proper lubrication for reliable operation.
Lubrication grooves and holes help distribute grease to the sliding contact surfaces.
Regular lubrication is important for reducing friction and wear.
The lubrication interval should be determined according to:
Applied loads
Movement frequency
Operating temperature
Environmental conditions
Lubricant characteristics
Bearing design
GXD…SA bearings incorporate a multi-groove lubrication arrangement, while GX…S and GE…AX designs may feature conventional lubrication grooves and holes.
When selecting thrust spherical plain bearings, engineers should consider the following factors:
Axial Load Requirements
Determine the magnitude and direction of the applied axial load.
Combined Loading
Evaluate whether radial loads are present and verify that they remain within the permissible limits.
Dynamic and Static Load Ratings
Select the bearing according to the relevant load ratings and operating conditions.
Bearing Dimensions
Confirm the bore diameter, outside diameter, overall height, and mounting dimensions.
Permissible Misalignment
Verify that the required angular movement is within the bearing's specified limits.
Lubrication Requirements
Ensure that suitable lubrication can be provided throughout the intended operating life.
Operating Environment
Consider temperature, contamination, vibration, and other relevant operating conditions.
