Ceramics / Hybrid Deep Groove Ball Bearing HC 63801 2RS TN GN 12x21x7 mm
Item number:
HC-63801-2RS-TN-GN
Item features:
The hybrid deep groove ball bearing HC-63801-2RS-TN-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 bearing steel
- cage material: plastic; the low weight and the elasticity of the plastic have a positive effect on the sliding and emergency running properties as well as the shock resistance; suitable for quiet running
- 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: 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
- gute Festlagereigenschaft, kann aber auch als Loslager eingesetzt werden, jeweils in beiden Richtungen
- 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)
