21310K Spherical roller bearing

21310K The 21310K is a spherical roller bearing with a 50 mm tapered bore (1:12 taper) from the 213 series. Spherical roller bearings feature two rows of barrel-shaped rollers running on a common spherical outer ring raceway, providing self-aligning capability to compensate for shaft misalignment and deflection. These bearings are designed for heavy radial loads and moderate thrust loads in applications such as gearboxes, industrial fans, pumps, mining equipment, and paper mill machinery. The tapered bore allows mounting directly onto tapered shafts or cylindrical shafts using adapter sleeves or withdrawal sleeves.
