Hybrid (Ceramics, Stainless Steel) Deep Groove Ball Bearing SS HC 63801 ZZ / 2Z GN 12x21x7 mm
Item number:
SS-HC-63801-ZZ-GN
Item features:
The hybrid deep groove ball bearing SS-HC-63801-ZZ / 2Z-GN has excellent properties due to the ceramic rolling elements. It is the wider version of the 68 series. It is particularly suitable for achieving a good load capacity in extremely limited space conditions. Main dimensions according to DIN 625-1.

Features
- designed as hybrid deep groove ball bearing: rolling elements made of ceramic, inner and outer ring made of stainless steel
- cage material: stainless steel; corrosion resistant and 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
- wider than comparable deep groove ball bearings of the series 68
- thin section bearing with very thin, rectangular cross section
- suitable for space-saving installation in radial and axial directions
- suitable for very 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: 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 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)
