21320-K Spherical roller bearing

21320-K The 21320-K is a spherical roller bearing from the 213 series with a 100 mm tapered bore (1:12 taper). 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 deflection or misalignment. These bearings are suitable for heavy radial loads and moderate axial loads in both directions. Common applications include industrial gearboxes, mining equipment, pulp and paper machinery, construction equipment, and wind turbines where shaft misalignment or deflection is expected during operation.
