GEM 20 ESX-2LS

SKF Explorer radial spherical plain bearing, virtually maintenance-free, sealed, metric sizes

Radial spherical plain bearings are designed to accommodate radial and combined radial and axial loads, and also misalignment.

This specific design includes an SKF Explorer steel/steel sliding contact surface combination. The bearings 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.

  • Designed for radial and combined radial and axial loads
  • Long service life
  • Virtually maintenance-free
  • Suitable for heavy static or impact loads
  • Extended inner ring can save spacer rings
