21310K-C3 Spherical roller bearing C3

21310K-C3 The 21310K-C3 is a spherical roller bearing with a 50mm tapered bore (1:12 taper) and C3 radial clearance. Spherical roller bearings feature 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, steel production machinery, and gearboxes where shaft misalignment and heavy radial loads are present. The tapered bore allows direct mounting on tapered shafts or via adapter sleeves on cylindrical shafts.
