Features
- suitable for very high radial load capacities and high speeds
- Variant NJ: semi- locating bearing, axially displaceable in one direction
- cage material: plastic; the low weight and the elasticity of the plastic have a positive effect on the sliding and emergency running properties as well as the shock resistance; suitable for quiet running
- 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)
