21315K Spherical roller bearing

21315K The 21315K is a spherical roller bearing from the 213 series with a 75 mm tapered bore (1:12 taper). Spherical roller bearings feature barrel-shaped rollers running on a spherical outer ring raceway, providing self-aligning capability to accommodate shaft deflection and misalignment. These bearings are commonly used in heavy industrial applications including mining equipment, pulp and paper machinery, gearboxes, and crushers where high radial loads, moderate thrust loads, and compensation for misalignment are required. The tapered bore enables mounting directly on tapered shafts or on cylindrical shafts using adapter sleeves or withdrawal sleeves.
