These matched sets of two super-precision, high-speed, E design, single row angular contact ball bearings with seals 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.
| Universal matching bearing(s) |
Yes, back-to-back (<>), face-to-face (><) or tandem (>>)
