Family specifications and selection conditions
| Product description | Double row deep groove ball bearings correspond, in their design and operation, to a pair of single row deep groove ball bearings. They are robust in operation, requiring little maintenance, can operate at high speeds and accommodate radial and axial loads in both directions. They are slightly wider than single row bearings of the same bore and outside diameter but have a considerably higher load carrying capacity. |
|---|---|
| Manufacturer features | Versatile and robust design • High-speed capability • Accommodate high axial and radial loads in both directions • Require little maintenance |
