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.
These bearings are commonly used in heavy industrial applications including mining equipment, paper mills, material handling systems, and gearboxes where shaft misalignment is present. The C4 clearance is suited for conditions involving thermal expansion, interference fits, or higher operating temperatures.
