1203
Self-aligning ball bearings feature two rows of balls running on a spherical outer ring raceway, allowing the bearing to accommodate angular misalignment between the shaft and housing. The 1203 has a 17 mm bore diameter and belongs to the 12 series.
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 design helps reduce stress on the bearing caused by misalignment.
