Double row angular contact ball bearing with split outer ring
Double row angular contact ball bearings, with split outer ring, correspond to a pair of single row angular contact ball bearings in a face-to-face arrangement, while requiring less axial space.
They can operate at very high speeds and are more suitable than deep groove ball bearings for supporting large axial forces.
- Split outer ring
- Accommodate very high axial loads in both directions, radial loads, 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
