About MR Series Smaller Outer Ring Size

MR series bearings are metric miniature ball bearings with a smaller outside diameter for their bore than the 600 series. The thin cross section keeps them light and compact, and they are used in small motors, RC models, instruments, fishing reels and other high speed, light load equipment.

Flanged versions carry an MF prefix. The flange locates the bearing against the housing face, so no shoulder or snap ring is needed. Stainless steel versions carry an S prefix. Open, shielded and sealed versions are available.

For larger outside diameters, see the 600 series. See all Metric Miniature Ball Bearings.
