Item number:
63801-V-2RS-GD1
Item features:
The deep groove ball bearing 63801-V-2RS-GD1 is the wider version of the full complement 68-V series. It is narrow and can also be used with limited space. Due to the maximum number of rolling elements, it is marked with the addition MAX (= maximum). Main dimensions according to DIN 625-1.

Features
- full complement ball system design: higher radial load capacity than comparable deep groove ball bearings with cage
- high impact resistance and rigidity due to larger number of rolling elements
- 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
- 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)
