22311K-C4 Spherical roller bearing C4

22311K-C4 The 22311K-C4 is a spherical roller bearing with a 55 mm tapered bore (1:12 taper) and C4 internal radial clearance. 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. This bearing type is commonly used in heavy industrial applications including mining equipment, paper mills, gearboxes, and construction machinery where moderate to heavy radial loads, self-alignment capability, and larger operating clearances are required. The tapered bore facilitates mounting on tapered shafts or adapter sleeves.
