22311 Spherical roller bearing 55x120x43mm

The 22311 is a spherical roller bearing with a 55mm bore diameter, 120mm outside diameter, and 43mm width. Spherical roller bearings feature barrel-shaped rollers running on a common spherical outer ring raceway, providing self-aligning capability to compensate for shaft deflection and misalignment.

These bearings are commonly used in heavy industrial applications including mining equipment, construction machinery, paper mills, and gearboxes where high radial loads, moderate thrust loads, and shaft misalignment conditions are present. The self-aligning design makes them suitable for applications with flexible shafts or difficult mounting conditions.
