Spherical roller bearings

The outstanding feature of all spherical roller bearings is angular adjustability. This is achieved with a double row rolling element set based on symmetrical barrel rollers, which orient themselves freely on the mutually curved raceway in the outer ring and the two raceways inclined relative to the bearing axis in the inner ring.

In addition to standard spherical roller bearings (without seals, with a tapered or cylindrical bore), specialised designs are available for special requirements:

  • spherical roller bearings for vibratory machinery
  • split spherical roller bearings for simplified bearing replacement
  • sealed spherical roller bearings.

Spherical roller bearings are suitable where:

  • bearing arrangements are subjected to high and very high radial loads
  • relatively high axial loads occur on one or both sides, in addition to high radial forces
  • dynamic or static misalignments of the shaft relative to the housing, or deflections of the shaft, must be freely compensated by the bearing
  • high shock type loads must be supported dynamically
  • locating bearings with a very high load carrying capacity are required
