Features
- miniature ball bearing with smallest dimensions
- suitable for high radial loads and light axial loads in both directions
- suitable for high running accuracy
- 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
- with increased radial internal clearance (C3): for high temperature gradient between the bearing rings or for fastening with press fit
- 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)
