22309-C4 is a spherical roller bearing, 45 mm bore × 100 mm OD × 36 mm wide (1.7717 × 3.937 × 1.4173 in). It has C4 internal clearance.
The 22309-C4 is a spherical roller bearing with a 45mm bore diameter from the 223 series, featuring C4 radial internal clearance for applications requiring greater clearance than standard C3. Spherical roller bearings use barrel-shaped rollers running on a spherical outer ring raceway, providing self-aligning capability to compensate for shaft deflection or misalignment.
