| *.Miniature bearings |

| The conrad
construction of the R series enables these bearings to take a radial thrust as well as a
radial load. The well designed ball complement and selection of retainers permit use of
this series in speed motor applications. This series is produced open, shielded or sealed.
Sealed bearings are made slightly wider as shown in the dimension table. |
