Miniature Deep Groove Ball Bearings of the series SSMR
- all components are made of stainless steel: the miniature ball bearing is, therefore, corrosion-resistant and hygienic
- 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 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
Stainless steel miniature deep groove ball bearings of the series MR are corrosion-resistant and have metrical special dimensions. They are comparatively small and have an inner diameter of 2 to 8 millimeters. 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 bearings: such 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 stainless steel miniature ball bearing SS-MR52-2RS is small and suitable for installation with limited space and on thin shafts. It can withstand very high speeds, has metric special dimensions and is resistant to corrosion.
Other options: Metal shield (ZZ) or rubber seal (2RS) can be provided.
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.
Common Options:
- ZZ– Two Metal Shields
- 2RS– Two Rubber Seals
- NR– Snap Ring
- M– Brass Cage
- C0– Normal Internal Clearance
- C3– Greater than normal
