22311 is a spherical roller bearing, 55 mm bore × 120 mm OD × 43 mm wide (2.1654 × 4.7244 × 1.6929 in).
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.
