Miniature Deep Groove Ball Bearings of the series SSR in inch sizes


  • 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: non-contact gap seal on both sides made of a profiled sheet steel disc (ZZ / 2Z) for higher speeds than with rubber seal
  • 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

Stainless steel miniature deep groove ball bearings of the series R with inch dimensions are corrosion-resistant, comparatively small and have an inner diameter from 2.38 to 9.525 millimetre. Therefore, they are suitable for relatively 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 high until 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 stainless steel miniature ball bearing SS-R133-ZZ / 2Z in inch-size is small and suitable for installation with limited space and on thin shafts. It can withstand very high speeds. It is resistant to corrosion.

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

Deep groove 6000a
Miniature Deep Groove Ball Bearings of the series SSR in inch sizes -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.

Common Options:

  • ZZ– Two Metal Shields
  • 2RS– Two Rubber Seals
  • NR– Snap Ring
  • M– Brass Cage
  • C0– Normal Internal Clearance
  • C3– Greater than normal
