Spherical Roller Bearings

Spherical roller bearings are principally provided with two rows of symmetrical spherical rollers and a common sphere raceway in the out ring, the two inner ring raceways are included at an angle to the bearing axial. The bearings have good self-aligning ability and can operate when the shaft deflection under load or the shaft deflection under load or the shaft misalignment in mounting, and their permissible aligning angle is 1 to 2.5 degree. This type of bearings has heavy load carrying capacity and anti-impact ability, in addition to radial loads, they also can carry axial loads in two directions. In general, this type of bearings permits a low limiting speed.

  1. Able to accommodate misalignment
  2. Suitable for high axial and some radial loads
  3. Relatively high-speed ratings
