OEM/ODM China Heavy Duty Pillow Block Bearings - 21304 SPHERICAL ROLLER BEARING WITH 20MM BORE – CWL Detail:
Most spherical roller bearings are designed with two rows of rollers, allowing them to take very heavy radial loads and heavy axial loads. There are also designs with one row of rollers, suitable for lower radial loads and virtually no axial load.
With the swiveling inner ring, the spherical roller bearing 21304 offers excellent alignment error compensation. It has two rings with barrel-shaped rollers as rolling elements and can absorb very high radial and also axial forces. Main dimensions according to DIN 635-2.
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
