Double row angular contact ball bearings

Double row angular contact ball bearings correspond in design and operation to a pair of single row angular contact ball bearings in a back-to-back configuration, while requiring less axial space. They can operate at high speeds and are more suitable than deep groove ball bearings for supporting large axial forces acting in both directions.

  • High speed capability
  • Can withstand high radial loads and high axial loads and tilting moments in both directions.
  • Ideal for situations requiring high stiffness bearing configurations
  • Requires less axial space than comparable single-row angular contact ball bearing pairs.
