Description

3311-A-TN9-C3 SKF

Double row angular contact ball bearing

Double row angular contact ball bearings correspond, in their design and operation, to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space, and are particularly suitable in applications where a stiff bearing arrangement is required. They can accommodate radial loads, axial loads in either direction and tilting moments. They can operate at very high speeds and are more suitable than deep groove ball bearings for supporting large axial forces.

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