Family specifications and selection conditions
| Product description | These super-precision, high-speed, E design, single row angular contact ball bearings, with 15° or 18° contact angle, accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. They are designed to accommodate very high speeds. Compared to the equivalent SKF B design high-speed bearings, have a slightly higher speed capability and can accommodate heavier loads. |
|---|---|
| Manufacturer features | Very high running accuracy • Accommodate very high speeds • Accommodate relatively high radial loads and large unilateral axial loads |
