Features
- suitable for extremely high radial load capacities, axial load capacities in one direction and high speeds
- wider than series 3 and suitable for slightly higher loads
- Variant NU: floating bearing. axially displaceable due to ribless inner ring
- cage material: sheet steel. Resistant to fatigue and wear; provide good protection against impact loads and acceleration forces
- 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)
