GE 12 C

Radial spherical plain bearing, maintenance-free, metric sizes
These spherical plain bearings have a steel/PTFE sintered bronze contact surface combination and are maintenance-free. The sliding surfaces have to be externally protected from contaminants. These bearings are also available with a wider inner ring and a larger outside diameter (suffix GEH), which enable higher load ratings and larger tilt angles.

  • Designed for radial and combined radial and axial loads
  • Long service life and maintenance-free
  • Suitable for heavy, constant direction loads
  • Low coefficient of friction
  • High operating temperatures
  • High sliding velocities and small operating clearances
