GEH 80 ESX-2LS
SKF Explorer radial spherical plain bearing, virtually maintenance-free, sealed, metric sizes
These radial spherical plain bearings have an SKF Explorer steel/steel sliding contact surface combination.
They are initially lubricated and have a triple-lip, heavy-duty contact seal on both sides. Compared to conventional steel/steel bearings, they have increased dynamic load ratings. Compared to the GE series, they have a wider inner ring and a larger outside diameter, which enable higher load ratings and larger tilt angles.
- Designed for radial and combined radial and axial loads
- Long service life
- Virtually maintenance-free
- Suitable for heavy static or impact loads
- Enable larger tilt angles
