22311K Spherical roller bearing

22311K The 22311K is a spherical roller bearing with a 55 mm tapered bore (1:12 taper) from the 223 series. Spherical roller bearings feature barrel-shaped rollers running on a spherical outer ring raceway, providing self-aligning capability to accommodate shaft deflection and misalignment. This bearing type is commonly used in heavy industrial applications including mining equipment, pulp and paper machinery, gearboxes, and conveyor systems where misalignment compensation and high radial load capacity are required. The tapered bore design facilitates mounting on tapered shafts or adapter sleeves.
