Features
- has conical rollers as rolling elements
- suitable for high combined loads in one direction
- is particularly axially resilient due to the pressure angle
- it has also an axial load carrying capacity on both sides in the X- or O-arrangement in pairs
- very good fixed bearing properties in one direction
- 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)
