Self-aligning ball bearings feature a double-row design with a common spherical raceway in the outer ring, allowing the bearing to compensate for angular misalignment between the shaft and housing. The 1204 designation indicates a Series 12 bearing with a 20mm bore diameter.
These bearings are commonly used in applications where shaft deflection or mounting errors are expected, such as agricultural equipment, conveyor systems, and wood processing machinery. The self-aligning capability reduces stress on the bearing and extends service life in challenging alignment conditions.
