Spherical plain bearing series E steel on steel , requiring maintenance, inch-sized. For use with high multidirectional loads.
SPB GEZ…ES-2RS inch spherical plain bearings are designed for heavy-load applications requiring oscillating movement, angular adjustment and additional protection against dust and external contaminants.
These radial spherical plain bearings feature steel-on-steel sliding contact surfaces. The inner ring has a convex spherical outside surface that slides against the matching concave spherical inside surface of the outer ring, allowing relative angular movement between connected components.
The GEZ…ES-2RS series is manufactured in inch dimensions, making it suitable for equipment designed around imperial measurement systems. Its robust construction supports demanding mechanical applications involving high loads and relatively slow oscillating or tilting movements.
The key feature of the GEZ…ES-2RS design is its two seals, one fitted on each side of the bearing. These seals help prevent dust and other external contaminants from entering the sliding contact area while helping retain lubricant.
Inch-size design: Suitable for equipment and assemblies using imperial dimensional specifications.
Steel-on-steel sliding surfaces: Designed for demanding applications involving heavy loads and oscillating movements.
Double-sided seals: Help protect the sliding surfaces against dust and external contaminants.
MoS₂-treated sliding surfaces: Molybdenum disulfide treatment supports sliding performance and wear resistance.
Relubrication capability: Annular lubrication grooves and holes in both rings facilitate grease replenishment.
Robust bearing construction: Hardened and phosphated bearing rings provide a durable structure for industrial applications.
Angular movement: The spherical sliding design accommodates angular misalignment between connected components.
Construction machinery often operates in dusty environments and contains articulated joints subjected to heavy loads and repeated movement. GEZ…ES-2RS bearings can be used in suitable pivot joints and linkage mechanisms where their dimensions and load ratings meet the application requirements.
The seals provide additional protection against dust and external contaminants that may otherwise enter the sliding contact area.
Agricultural equipment, including tractors and harvesting machinery, frequently operates outdoors in environments containing dust, soil and other contaminants. GEZ…ES-2RS bearings may be suitable for articulated connections and linkage systems requiring load support, angular movement and additional contamination protection.
Industrial machinery often incorporates pivoting connections between moving components. GEZ…ES-2RS bearings can be considered for suitable mechanical linkages and articulated joints where heavy-load support, oscillating movement and protection against external contamination are required.
Hydraulic equipment may require articulated connections that accommodate angular movement during operation. GEZ…ES-2RS bearings can be considered for selected hydraulic equipment mounting arrangements, provided the bearing dimensions, load ratings and permissible movement meet the design requirements.
Certain off-road vehicles and heavy-duty equipment use spherical plain bearings in articulated mechanisms and suspension-related connections. The sealed GEZ…ES-2RS design may be suitable where additional protection against dust and contaminants is desirable.
The main difference is the sealing arrangement.
GEZ…ES is the open version without additional side seals. It is suitable for applications where the operating environment is relatively clean and lubrication and maintenance can be performed regularly.
GEZ…ES-2RS features two additional seals, one on each side of the bearing. These seals help reduce the entry of dust and external contaminants and help retain lubricant around the sliding surfaces.
| Feature | GEZ…ES | GEZ…ES-2RS |
|---|---|---|
| Design | Open type | Double-sealed type |
| Additional seals | No | Two, one on each side |
| Dust protection | No additional side seals | Improved protection against dust and external contaminants |
| Typical environment | Relatively clean conditions | Dusty or contaminated conditions |
| Maintenance | Requires relubrication | Also requires maintenance and relubrication according to the product design |
The 2RS seals improve contamination protection but do not make the bearing completely waterproof or maintenance-free.
GEZ…ES-2RS bearings are maintenance-required spherical plain bearings. The lubrication grooves and holes allow grease replenishment according to the bearing design and maintenance requirements.
The lubrication interval and grease selection should be determined according to the applied load, movement frequency, operating temperature and working environment. Regular inspection is recommended to help maintain reliable sliding performance.
SPB Bearings supplies spherical plain bearings for industrial machinery, construction equipment, agricultural machinery and other articulated applications.
When selecting a GEZ…ES-2RS bearing, it is important to verify the inch dimensions, load ratings, permissible angular movement, lubrication requirements and operating conditions. Correct bearing selection helps ensure compatibility with the equipment and its intended application.
