Family specifications and selection conditions
| Product description | 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. They can operate at high speeds and are more suitable than deep groove ball bearings for supporting large axial forces in both directions. |
|---|---|
| Manufacturer features | 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 |
