Features
- angular ball bearing with one row of balls
- suitable for high radial loads and axial loads in one direction
- it has also an axial load carrying capacity on both sides in the X- or O-arrangement in pairs
- suitable for high running accuracy, quiet running and high speeds
- cage material: sheet steel, high load-bearing capacity and high strength; suitable for continuous high temperatures
- 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
- A pictorial representation of the correct installation direction can be found here: for representation
- good fixed bearing property in the X- or O-arrangement in pairs
- 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)
