The 22318-C3 is a spherical roller bearing with a 90mm bore diameter from the 223 series, featuring C3 radial internal clearance for applications requiring greater clearance than normal. Spherical roller bearings use barrel-shaped rollers running on a common spherical outer ring raceway, providing self-aligning capability to accommodate shaft misalignment and deflection.
These bearings are commonly used in heavy industrial machinery including paper mills, mining equipment, gearboxes, wind turbines, and vibratory applications where shaft deflection or misalignment is expected. The C3 clearance makes this bearing suitable for applications with thermal expansion, interference fits, or operating conditions that reduce internal clearance.
