About Self Aligning Ball Bearing

  • Self-aligning ball bearings have a spherical outer ring raceway, the center of whose curvature meets that of the bearing itself, so that the inner ring, balls, and cage continue to rotate, aligning themselves if they have become misaligned within design limits.
  • This type of bearing is suitable when the displacement of the centers around which the shaft and housing rotate and shaft deflection are likely to occur.
  • Bearings with a tapered bore can easily be fit to the shaft with an adapter assembly.

Features of Self Aligning Ball Bearing

  • The Self-Aligning ball bearing has two rows of balls.
  • The balls roll on a spherical outer ring raceway.
  • The inner ring, balls, and retainer can align themselves and accommodate for the shaft and housing misalignment and deflections.
  • The tapered bore design allows for easy mounting with an adaptor sleeve.
  • Pressed steel cages are either a staggered or snap-type.

Main Applications

  • Power transmission shafts of woodworking and spinning machines Plummer blocks.
