Features
- designed as hybrid deep groove ball bearing: rolling elements made of ceramic, inner and outer ring made of bearing steel
- cage material: sheet steel, high load-bearing capacity and high strength; suitable for continuous high temperatures
- lighter than comparable deep groove ball bearings with steel balls as rolling elements; ceramic balls have a current-insulating effect; withstands higher speeds and has a high wear resistance
- thin section bearing with ultra-thin cross section
- suitable for space-saving installation in radial and axial directions
- suitable for extremely high speeds compared to deep groove ball bearings with a larger cross section
- extra light series with compact dimensions and low weight
- suitable for radial loads and light axial loads in both directions
- offers high running accuracy, quiet running and very high speeds
- seal: open (without seal); for higher speeds than with sealed ball bearings and easy relubrication
- 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)
