Product Features
The Features of SPHERICAL ROLLER BEARING
1. Spherical roller bearing with two rows of rollers
2. pivoting inner ring, misalignments and shaft deflections can be compensated
3. suitable for very high radial and relatively high axial loads in both directions
4. medium series with compact dimensions and average weight
5. cage material: brass. Steel,Special strength and durability under extreme conditions such as shock loads and vibrations, high acceleration forces and lack of lubrication
6. seal: open (without seal); for higher speeds than with sealed spherical roller bearings and easy relubrication
