Self-aligning ball bearings

Self-aligning ball bearings are recommended when alignment of the shaft and housing poses difficulty. These bearings have two rows of balls and a common sphered raceway in the outer ring. The bearings generate less friction than other types of rolling bearings, hence enabling them to run cooler even at high speeds. Pressed steel cages are most widely used in this type of bearings. Some series of the self-aligning ball bearings are available with seals.

Following types of self-aligning ball bearings designs are available:

  • Basic design bearings
  • Bearings with an extended inner ring
  • Sealed bearings


  • Papermaking Machinery
  • Semiconductor
  • Gearboxes
