GEH 20 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
