Self-Aligning Ball Bearings

Self-aligning ball bearings are double-row ball bearings with a common spherical outer ring raceway, allowing the bearing to compensate for shaft misalignment.

Self-Aligning Ball Bearings

Design Features

  • Double row ball bearing with two inner ring raceways and a common sphered outer ring raceway
  • With pressed steel and polyamide resin cage options
  • With cylindrical and tapered bores
  • Available as open bearings or with contact seal (for series 22 and 23)
  • Radial internal clearances C2, C-normal, C3 and C4
  • Dimension series 12, 13, 22 and 23
  • For shaft diameters ranging from 5 to 110 mm

Operating Benefits

  • Accommodate angular misalignment caused by shaft deflection
  • Compensation for inaccuracy of shaft and housing alignment during mounting
  • Efficient alternative to spherical roller bearings for high-speed and light-load applications

Fields of Application including

  • Agricultural machinery
  • Conveyors and material handling
  • Fans and blowers
  • Gearbox and drives
