Family specifications and selection conditions
| Product description | These matched sets of two super-precision, high-speed, E design, single row angular contact ball bearings are available in a variety of arrangements. Compared to the equivalent SKF B design high-speed bearings, these have a slightly higher speed capability and can accommodate heavier loads. |
|---|---|
| Manufacturer features | Very high running accuracy • Accommodate very high speeds |
