Deep Groove Ball Bearing with a Flanged Outer Ring F6903 / 6903 2RS 17x30x7 mm
Item number:
F-6903-2RS
Item features:
Narrow, light and with very good spinning characteristics. The deep groove ball bearing F-6903-2RS is narrow and can also be used with limited space. The low weight allows for very high speeds. With the flange, it can be fixed axially, e.g. in bore holes.

Features
- the flange on the outer ring prevents axial displacements
- thin section bearing with a thin 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
- 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)
