2319-C3 is a self-aligning ball bearing, 95 mm bore × 200 mm OD × 67 mm wide (3.7402 × 7.874 × 2.6378 in). It has C3 internal clearance.
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 2319-C3 has a 95mm bore diameter and C3 internal clearance, providing greater radial clearance than standard for applications with thermal expansion or fitting interference.
