6904 2RS /61904 2RS dry Deep Groove Ball Bearing
The hybrid deep groove ball bearing C-6904-2RS has excellent properties due to the ceramic rolling elements. It is narrow and can also be used in a limited space. The low weight allows very high speeds.
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 a thin, square cross section
-
suitable for space-saving installation in radial and axial directions
-
suitable for 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
-
good fixed bearing property, but can also be used as a floating bearing, each in both directions
