The 1304 is a self-aligning ball bearing with a 20mm bore diameter from the 13 series. Self-aligning ball bearings feature a double row of balls running on a spherical outer ring raceway, allowing the bearing to accommodate angular misalignment between the shaft and housing.
These bearings are commonly used in applications where shaft deflection or mounting errors cause misalignment, including agricultural equipment, conveyor systems, textile machinery, and woodworking equipment. The self-aligning design helps prevent premature failure due to misalignment while maintaining smooth operation.
