23218K Spherical roller bearing

23218K The 23218K is a spherical roller bearing from the 232 series with a 90mm 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 accommodate shaft deflection and misalignment. These bearings are commonly used in heavy industrial applications including mining equipment, construction machinery, paper mills, and gearboxes where high radial loads, moderate thrust loads, and misalignment compensation are required. The tapered bore design allows direct mounting on tapered shafts or adapter sleeves.
