Features
- Spherical roller bearing with two rows of rollers
- pivoting inner ring, misalignments and shaft deflections can be compensated
- suitable für very high radial and relatively high axial loads in both directions
- medium series with compact dimensions and average weight
- with tapered bore for mounting by means of adapter sleeve
- cage material: brass. Special strength and durability under extreme conditions such as shock loads and vibrations, high acceleration forces and lack of lubrication
- seal: open (without seal); for higher speeds than with sealed spherical roller bearings and easy relubrication
- 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)
