Spherical plain thrust bearing. Mating surface hard chromium/PTFE, maintenance free. For use with axial loads.
Steel/PTFE Sliding Contact | Self-Lubricating | High Axial Load Capacity | Metric Series
GX…T / GE…AW / GXD…TX Thrust Spherical Plain Bearings are maintenance-free bearings designed primarily to accommodate axial loads acting in one direction while allowing angular movement and limited misalignment between connected components.
Featuring steel/PTFE-based sliding contact combinations, these bearings provide self-lubricating performance and reduce the need for routine maintenance.
The 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 transmit axial forces while accommodating angular movement between the washers.
Unlike conventional steel-on-steel thrust spherical plain bearings, maintenance-free designs incorporate PTFE-based sliding materials to provide low-friction operation without routine grease replenishment under specified operating conditions.
The GX…T and GE…AW series are commonly used designations for maintenance-free thrust spherical plain bearings, while the GXD…TX series represents a high-performance steel/PTFE fabric design intended for demanding load applications.
These bearings can be considered for industrial machinery, hydraulic equipment, mechanical actuators, and other assemblies requiring axial load support and angular movement.
PTFE-based sliding materials provide self-lubricating performance, eliminating the need for routine relubrication under specified operating conditions.
This makes these bearings particularly suitable for applications where regular maintenance is difficult or undesirable.
Thrust spherical plain bearings are designed primarily to accommodate axial loads acting in one direction.
Their spherical sliding surfaces transmit thrust forces through the bearing assembly.
In addition to axial loads, thrust spherical plain bearings may accommodate radial load components within specified limits.
Axial loading should remain the dominant load component.
The permissible combined loading depends on the bearing design and manufacturer's specifications.
The sliding contact combination incorporates a hardened steel surface and a PTFE-based liner.
This construction provides low-friction sliding contact and self-lubricating performance.
The specific liner material and construction may differ between bearing series and manufacturers.
In typical GX…T / GE…AW designs, the spherical sliding surface of the shaft washer is hardened, ground, polished, and hard chrome plated.
The surface treatment provides a suitable counterface for the PTFE-based liner.
The spherical sliding contact surfaces allow limited angular misalignment between the shaft washer and housing washer.
The permissible tilt angle depends on the bearing dimensions and mounting arrangement.
Thrust spherical plain bearings generally consist of separable shaft and housing washers.
This construction facilitates installation in suitable mechanical assemblies.
GX…T / GE…AW / GXD…TX bearings belong to metric thrust spherical plain bearing families.
Different sizes are available to meet various industrial equipment requirements.

GX…T bearings are metric thrust spherical plain bearings featuring a self-lubricating sliding contact combination.
They are designed primarily to support axial loads acting in one direction while accommodating limited angular movement.
Their PTFE-based sliding contact construction reduces the need for routine maintenance.
GX…T bearings can be considered for applications where lubrication access is limited or where maintenance-free operation is preferred.
GE…AW bearings are another commonly used designation for maintenance-free thrust spherical plain bearings.
In a typical GE…AW design, the shaft washer is manufactured from hardened bearing steel with a hard-chrome-plated spherical sliding surface.
The housing washer incorporates a bonded PTFE-based liner.
The combination provides self-lubricating sliding contact and allows the bearing to accommodate axial loading and angular movement.
Certain GE…AW and GX…T models are listed as corresponding designs in manufacturer interchange references.
However, actual interchangeability should be verified according to dimensions, load ratings, liner construction, and operating requirements.
GXD…TX bearings are high-performance maintenance-free thrust spherical plain bearings featuring a steel/PTFE fabric sliding contact combination.
This design is intended for applications involving substantial axial loads or combined axial and radial loading.
The PTFE fabric sliding surface provides self-lubricating performance and a low coefficient of friction.
GXD…TX bearings are generally supplied in an open design without integral seals.
Their suitability for a specific application should be evaluated according to the manufacturer's load ratings and technical specifications.
GX…T / GE…AW / GXD…TX Maintenance-Free Thrust Spherical Plain Bearings can be considered for a variety of industrial applications.
Hydraulic machinery may incorporate thrust spherical plain bearings in suitable mechanisms where axial loads and angular movement occur.
Maintenance-free designs can be useful where regular lubrication is difficult.
Construction equipment often operates under demanding mechanical conditions.
Maintenance-free thrust spherical plain bearings may be considered for suitable articulated assemblies requiring axial load support.
Agricultural equipment frequently operates in environments involving dust, vibration, and changing mechanical loads.
Self-lubricating bearings may help reduce routine lubrication requirements in suitable applications.
Automated machinery may require compact mechanical connections capable of accommodating axial forces and limited angular movement.
Maintenance-free thrust spherical plain bearings can be considered where the operating conditions are compatible with their design.
Selected material handling and positioning mechanisms may benefit from thrust spherical plain bearings where axial loads are dominant.
Certain actuator assemblies require components capable of transmitting axial forces while accommodating angular misalignment.
Thrust spherical plain bearings can be considered where their load ratings and mounting arrangements meet the application requirements.
Maintenance-free thrust spherical plain bearings use PTFE-based sliding materials to reduce friction between the spherical contact surfaces.
Unlike steel-on-steel bearings, these designs generally do not require routine grease replenishment.
This can help reduce maintenance requirements, particularly in applications where the bearing is difficult to access.
However, maintenance-free does not mean unlimited service life.
Bearing performance depends on several factors, including:
Applied axial and radial loads
Oscillation angle and movement frequency
Operating temperature
Contamination
Installation accuracy
Sliding contact material
Operating environment
Lubrication practices should follow the requirements of the specific bearing design. Additional grease should not be applied unless permitted by the manufacturer.

The appropriate bearing design should be selected according to the actual operating conditions.
When selecting maintenance-free thrust spherical plain bearings, the following factors should be considered.
Axial Load Requirements
Determine the magnitude and direction of the applied axial load.
Combined Loading
Evaluate any radial load components and verify that the bearing can accommodate the resulting combined loading.
Dynamic and Static Load Ratings
Confirm that the selected bearing has suitable load ratings for the application.
Bearing Dimensions
Check the bore diameter, outside diameter, bearing height, and installation dimensions.
Angular Misalignment
Verify that the required tilt angle is within the bearing's permissible limits.
Sliding Contact Material
Select the appropriate PTFE-based liner construction according to the application requirements.
Operating Temperature
Confirm that the operating temperature remains within the permissible range of the specific bearing design.
Environmental Conditions
Consider dust, moisture, contamination, and other environmental factors.
Installation Requirements
Ensure that the bearing is installed correctly and that the mounting arrangement provides adequate support.
