Double row angular contact ball bearing with seals

Double row angular contact ball bearings, with seals, correspond to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space.

Depending on the sealing execution, they can operate at high speeds and are more suitable than deep groove ball bearings for supporting large axial forces in both directions.

  • High-speed capability
  • Accommodate relatively high radial loads, high axial loads in both directions and tilting moments
  • Suitable where a stiff bearing arrangement is required
  • Require less axial space than equivalent pair of single row angular contact ball bearings
  • Integral sealing prolongs bearing service life
