1313 is a self-aligning ball bearing, 65 mm bore × 140 mm OD × 33 mm wide (2.5591 × 5.5118 × 1.2992 in).
Self-aligning ball bearings feature two rows of balls running on a spherical outer ring raceway, allowing the bearing to accommodate misalignment between the shaft and housing. This 13 series bearing has a 65mm bore diameter and provides reliable operation in applications with shaft deflection or mounting errors.
