Miniature Deep Groove Ball Bearings of the series C-MR 

  • designed as hybrid miniature ball bearing: rolling elements made of ceramic, inner and outer ring made of stainless steel
  • lighter than comparable miniature ball bearings with steel balls as rolling elements; ceramic balls have a current-insulating effect; withstands higher speeds and has a high wear resistance
  • 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
  • cage material: stainless steel; corrosion-resistant and suitable for continuous high temperatures
  • 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 as FAG, 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

Hybrid bearings of the series C-MR in miniature size are furnished with low-wear, power-isolating ceramic balls which withstand an extremely high rotational speed. The bearings have metrical special dimensions, are comparatively small and have an inner diameter from 2 to 8 millimetre. 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.

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.

The hybrid miniature ball bearing SS-C-MR52-2RS has excellent properties due to the ceramic rolling elements. It is small and suitable for installation with limited space and on thin shafts. It can withstand extremely high speeds and has metric special dimensions.

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

Deep groove 6000a
Miniature Deep Groove Ball Bearings of the series C-MR -TFL

Deep Groove Ball Bearings are able to accommodate low to heavy radial loads and low to moderate thrust loads in either direction. They are available with metal shields (ZZ) or rubber seals (2RS). Several tolerance grades (Abec 1-9), internal clearance (C2 to C4) and cage designs are available to best suit the running precision and speed of the application.
