  • thin section bearing with a thin cross section
    • 

  • suitable for space-saving installation in radial and axial directions
    • 

  • extra light series with compact dimensions and low weight
    • 

  • suitable for radial loads and light axial loads in both directions
    •  
  • offers high running accuracy and quiet running
    • 

  • seal: non-contact gap seal on both sides made of a profiled sheet steel disc (ZZ / 2Z)
    • 

  • 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, etc. assign different suffixes for their characteristics, for better orientation take note of the comparison table of bearings (see further information)
