Self-aligning roller bearing

Self aligning roller bearings have two rows of rollers, which mainly bear radial loads and can also bear axial loads in any direction. They have high radial load capacity and are particularly suitable for working under heavy loads or vibration loads, but cannot withstand pure axial loads. They have automatic alignment function, that is, the bearing itself can be adjusted, and the angle alignment error between the inner and outer rings. Under normal load and working conditions, when the inner ring rotates, the misalignment values given in the table below are allowed. Whether this given value can be fully achieved depends on the design and sealing type of the bearing configuration. Spherical roller bearings are designed for high radial loads or even environments with eccentricity, improper lubrication, impurities, extremely high speed, or high stress.
