Miniature Deep Groove Ball Bearings of the series MR


  • miniature ball bearing with smallest dimensions
  • suitable for high radial loads and light axial loads in both directions
  • suitable for high running accuracy, quiet running, and very high speeds
  • seal: contact lip seal on both sides made of rubber (2RS) for high sealing effect
  • If you need this bearing in RS design with only one seal and one open side, you can simply remove one of the two seals: to the instructions
  • good fixed bearing property, but can also be used as a floating bearing, each in both directions
  • manufacturers of bearings, such asFAG, KOYO, NSK, SKF, SNR, OEM, etc. assign different suffixes for their characteristics, for better orientation take note of the comparison table of bearings (see further information)

Special feature of this series

Miniature deep groove ball bearings of the series MR with metrical special dimensions are comparatively small and have an inner diameter from 2 to 8 millimetres. Therefore, they are suitable for thin shafts and axis as well as for appropriate small space requirements. In the ratio to its small size, miniature deep groove ball bearings can take up relatively high loads. They are suitable for an extremely high rotational speed.

Manufacturers of bearingssuch as FAG, KOYO, NSK, SKF, SNR, etc. assign different suffixes for their characteristics, for better orientation take note of the comparison table of bearings (see further information)

Can be customized to meet your specific needs.

For use in special conditions. The miniature ball bearing MR is small and suitable for installation with limited space and on thin shafts. It can withstand very high speeds. It has metric special dimensions.

Other options: Metal shield (ZZ) or rubber seal (2RS) can be provided.
