21312K Spherical roller bearing

21312K The 21312K is a spherical roller bearing with a 60 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, allowing them to accommodate misalignment and deliver high radial and moderate axial load capacity. These bearings are commonly used in heavy industrial applications including mining equipment, construction machinery, gearboxes, paper mills, and industrial fans where shaft deflection or mounting misalignment is expected. The tapered bore design enables direct mounting onto tapered shafts or adapter sleeves for simplified installation and removal.
