Angular contact spherical plain bearing. Mating surface hard chromium/PTFE, maintenance free. For use at unidirectional, dynamic radial and additional axial loads.
Steel/PTFE Fabric | Metric Series | Self-Lubricating | Maintenance-Free Design
GAC…T / GE…SW Angular Contact Spherical Plain Bearings are metric-series, maintenance-free bearings designed to accommodate combined radial and axial loads while allowing angular movement and misalignment.
Featuring a steel/PTFE fabric sliding contact combination, these bearings provide self-lubricating performance, making them suitable for applications where regular relubrication is difficult or undesirable.
The bearings consist of an inner ring with a convex spherical sliding surface and an outer ring with a corresponding concave spherical sliding surface. Unlike conventional radial spherical plain bearings, the sliding contact surfaces are inclined relative to the bearing axis, enabling the bearings to support axial loads acting in one direction together with radial loads.
The inner ring is typically manufactured from hardened bearing steel with a hard-chrome-plated spherical sliding surface. The outer ring is generally made from bearing steel with a PTFE-based fabric liner bonded to its inner spherical surface.
The combination of a hardened steel sliding surface and a PTFE fabric liner provides low-friction operation and eliminates the need for routine relubrication under suitable operating conditions.
GAC…T / GE…SW bearings are widely considered for industrial machinery, hydraulic systems, mechanical linkages, and articulated assemblies requiring combined load support and maintenance-free operation.
The PTFE fabric liner provides self-lubricating properties, eliminating the need for regular grease replenishment under specified operating conditions.
This design is particularly suitable for applications where maintenance access is limited or where frequent lubrication would be inconvenient.
The inclined spherical sliding surfaces enable the bearing to accommodate combined radial and axial loads.
A single bearing supports axial loads acting in one direction. For applications requiring axial load support in both directions, a suitable opposed bearing arrangement may be necessary.
The sliding contact combination consists of a hardened steel inner ring and a PTFE-based fabric liner bonded to the outer ring.
This design provides low friction and good load-carrying capability for suitable oscillating and articulated movements.
The spherical sliding surface of the inner ring is typically hard chrome plated to improve surface hardness and wear resistance.
The outer ring incorporates a PTFE-based fabric liner that provides self-lubricating sliding contact.
The liner helps reduce friction and wear without requiring regular grease lubrication.
The spherical sliding contact design accommodates limited angular misalignment between connected mechanical components.
The permissible misalignment angle depends on the bearing size and installation arrangement.
GAC…T / GE…SW bearings are available in metric dimensions for a range of industrial machinery and mechanical assemblies.
These bearings are generally supplied in an open configuration without integral contact seals.
Appropriate protection against excessive contamination should be considered according to the operating environment.

GAC…T / GE…SW Maintenance-Free Angular Contact Spherical Plain Bearings can be considered for a wide range of industrial applications, including:
Hydraulic cylinders and actuator connections
Construction and engineering machinery
Agricultural equipment
Industrial automation systems
Material handling equipment
Lifting and positioning mechanisms
Mechanical linkage assemblies
Articulated industrial equipment
Machinery with limited maintenance access
Their self-lubricating design makes them particularly useful in applications where regular grease replenishment is difficult or undesirable.
Actual bearing suitability depends on the applied loads, movement characteristics, operating temperature, environmental conditions, and installation arrangement.
Unlike steel-on-steel angular contact spherical plain bearings, GAC…T / GE…SW bearings use a PTFE fabric sliding layer to provide self-lubricating performance.
Under suitable operating conditions, these bearings do not require routine relubrication.
This can help reduce maintenance requirements and simplify equipment servicing.
However, maintenance-free does not mean unlimited service life.
Bearing performance and service life depend on load, movement frequency, operating temperature, contamination, installation accuracy, and the characteristics of the PTFE liner.

The appropriate bearing series should be selected according to the actual operating conditions and engineering requirements.
When selecting GAC…T / GE…SW Angular Contact Spherical Plain Bearings, the following factors should be considered:
Bore diameter and outside diameter
Inner and outer ring widths
Radial and axial load requirements
Direction of axial loading
Dynamic and static load ratings
Permissible misalignment angle
Oscillation frequency and movement characteristics
Operating temperature
Environmental conditions
Installation and mounting requirements
For applications involving axial loads acting in both directions, an opposed bearing arrangement should be evaluated.
