The 1303 is a self-aligning ball bearing with a 17mm bore diameter from the 13 series. Self-aligning ball bearings feature two rows of balls running on a spherical outer ring raceway, allowing the bearing to automatically compensate for angular misalignment between the shaft and housing.
These bearings are commonly used in applications where shaft deflection or mounting errors may occur, such as agricultural equipment, conveyor systems, textile machinery, and woodworking equipment. They provide reliable performance in conditions where precise alignment cannot be maintained.
