23218-C4 Spherical roller bearing C4

23218-C4 The 23218-C4 is a spherical roller bearing with a 90mm bore diameter from the 232 series, featuring C4 radial internal clearance for applications requiring greater clearance than standard C3. Spherical roller bearings use barrel-shaped rollers running on a common spherical outer ring raceway, providing self-aligning capability to accommodate shaft deflection and misalignment. These bearings are commonly used in heavy industrial applications including mining equipment, construction machinery, paper mills, and gearboxes where shaft misalignment and high radial loads are present. The C4 clearance is typically specified for applications with interference fits, high operating temperatures, or where thermal expansion requires additional internal space.
