GEM 45 ES-2RS

Radial spherical plain bearing, requiring maintenance, 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 a steel/steel sliding contact surface combination, an extended inner ring and a double-lip contact seal on both sides. The bearings require maintenance and can be relubricated via lubrication holes and an annular groove in both rings.

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