Spherical plain bearing series G steel on steel, DIN ISO 12240-1. Treated with molybdenum disulphide mos2, regreasable. For use with higher pivoting angle.
SPB GEG…ES radial spherical plain bearings are designed for heavy-duty applications requiring high load-carrying capacity, angular movement and reliable performance under demanding operating conditions.
The bearing consists of an inner ring with a convex spherical outside surface and an outer ring with a matching concave spherical inside surface. This spherical sliding design accommodates misalignment between the shaft and housing and allows oscillating, tilting and slewing movements at relatively low sliding speeds.
Compared with standard GE…ES spherical plain bearings of the same bore diameter, GEG…ES bearings feature a larger outside diameter and a wider inner ring, providing a more robust design for applications requiring higher load capacity and greater angular movement.
Heavy-duty design: The larger dimensions compared with standard GE…ES bearings provide increased load-carrying capacity for demanding applications.
Accommodates misalignment: The spherical sliding contact allows angular adjustment between connected components.
Suitable for oscillating movements: Designed for applications involving slow oscillating, tilting or slewing movements.
Steel-on-steel sliding surfaces: Both rings feature steel sliding surfaces treated with molybdenum disulfide (MoS₂) to support wear resistance and sliding performance.
Relubrication capability: The ES design features annular lubrication grooves and lubrication holes in both rings, allowing grease replenishment during maintenance.
Robust construction: Hardened and phosphated bearing rings help provide wear resistance under demanding operating conditions.
GEG…ES spherical plain bearings are suitable for machinery and equipment that require high load capacity, angular movement and reliable articulation. Typical applications include:
Construction machinery: Pivot joints and articulated connections in excavators, loaders and other heavy equipment.
Agricultural machinery: Articulating joints and linkage mechanisms in agricultural equipment.
Hydraulic equipment: Suitable bearing arrangements for selected hydraulic cylinder connections and articulated mechanisms, subject to load and dimensional requirements.
Industrial machinery: Pivot points, linkage systems and mechanical connections exposed to heavy loads or alignment variations.
Commercial vehicles and transport equipment: Articulated joints and suspension-related mechanisms where the bearing's specifications meet the application requirements.
The final bearing selection should be based on the required dimensions, load ratings, permissible angular movement, lubrication conditions and operating environment.
Both GEG…ES and GE…ES are radial spherical plain bearings with steel-on-steel sliding contact surfaces and relubrication features. The main difference is their dimensional design and load-carrying capability.
GE…ES is the standard series for general radial spherical plain bearing applications.
GEG…ES is the larger, heavy-duty design. For the same nominal bore diameter, it generally has a larger outside diameter and a wider inner ring, providing greater load capacity and making it suitable for more demanding applications.
| Feature | GE…ES | GEG…ES |
|---|---|---|
| Design | Standard radial spherical plain bearing | Heavy-duty radial spherical plain bearing |
| Outside diameter | Standard dimensions | Larger for the same bore size |
| Inner ring width | Standard dimensions | Wider for the same bore size |
| Load capacity | Depends on the specific size and rating | Generally higher for the corresponding bore size |
| Lubrication | Lubrication grooves and holes in both rings | Lubrication grooves and holes in both rings |
| Typical use | General industrial applications | Heavy-load and more demanding articulated applications |
Note: Actual dimensions, dynamic and static load ratings, and permissible angular movement vary by bearing size. Always refer to the relevant product data before selecting a bearing.
The GEG…ES-2RS version is fitted with seals on both sides to help protect the sliding surfaces from dust and external contaminants. The standard GEG…ES version is open and does not have these seals.
According to the referenced product specifications, GEG…ES is rated for an operating temperature range of −50°C to +150°C, while GEG…ES-2RS is rated for −30°C to +130°C. Please confirm the applicable temperature limits against the exact model and current product specification.
