Family specifications and selection conditions
| Product description | Single row deep groove ball bearings are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. Also available on request with special sized bore and/or outside diameters, suitable for reworked shafts and housings. |
|---|---|
| Manufacturer features | Simple, versatile and robust design • Low friction • High-speed capability • Accommodate radial and axial loads in both directions • Require little maintenance |
