GEF...EF Series Radial Spherical Plain Bearings (GEF12ES GEF15ES GEF20ES GEF22ES GEF25ES GEF30 ES GEF35ES GEF40ES )
Spherical plain bearings are used for applications requiring rotation and oscillation. The rotation takes place on a sliding
surface so the limiting speed is slow.
We can supply high quality and almost all types of spherical plain bearing,
- Radial Spherical Plain Bearings
- Angular Contact Spherical Plain Bearings
- Thrust Spherical Plain Bearings
- Non-standard Spherical Plain Bearings
Applications:
Railway engineering
Railway station construction
Bridge building
Construction machinery
Hydraulic steel structures
Roof designs
Power generation
Oil field exploration
Mining and aggregate processing
Wind turbines
Gear drives
Rolling mills


Technical specification
Here is the comparison between each standard organization:
ABEC-1, ABEC-3, ABEC-5, ABEC-7, ABEC-9, the larger the number, the higher the precision grade.
| ANSI Standard* | DIN 620* | ISO 492* |
| ABEC 1 | P0 | Class Normal |
| ABEC 3 | P6 | Class 6 |
| ABEC 5 | P5 | Class 5 |
| ABEC 7 | P4 | Class 4 |
| ABEC 9 | P2 | Class 2 |
1) Sliding contact surfaces: Steel vs. Steel.
2) Materials: Both outer race and inner race are made of high chrome bearing steel.
3) Heat treatment: Both outer race and inner race are quenched (hardened), surface phosphorized.
4) Features of structure: With oil groove and oil hole, with an axial split in outer race.
5) Lubricant: molybdenum disulfide.
6) Properties: Good wearability, corrosion resistance, self-alignment.
