Family specifications and selection conditions
| Product description | Single row deep groove ball bearings with a snap ring groove 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. An annular groove in the outer ring enables the bearings to retain a snap ring. Also available on request with special sized bore and/or outside diameters, suitable for reworked shafts and housings. |
|---|---|
| Manufacturer features | Can accommodate a snap ring • Simple, versatile and robust design • Low friction and high-speed capability • Accommodate radial and axial loads in both directions • Require little maintenance |
