21307
The 21307 is a spherical roller bearing with a 35mm bore diameter, 80mm outside diameter, and 21mm width. Spherical roller bearings feature two rows of barrel-shaped rollers running on a common sphered 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, construction machinery, gear reducers, pumps, and rolling mills where high radial loads, moderate thrust loads, and misalignment compensation are required. The self-aligning design allows angular misalignment up to approximately 1-2.5 degrees.
