22213E/C3 Spherical Roller Bearings, Stamped Steel Cages
The 22213E/C3 Double-row spherical roller bearings are suitable for heavy-load, impact, and eccentric conditions. Classic applications include vibrating screen exciters, crushers, fans, paper machine press rolls, mining conveyor equipment, and marine propulsion shafts.
The 22213E/C3 bearing is a Spherical roller bearings, double row with an inner diameter of 65 mm , an outer diameter of 120 mm, a width of 31 mm. High-carbon chromium steel rings, High-carbon chromium steel rolling mlement. Its dynamic radial rated load is approximately 197459 N, its static radial rated load is approximately 215777 N. It uses C3 standard radial clearance, open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
22213E/C3 bearings ( 65 mm x 120 mm x 31 mm) have the advantages of Self-aligning, high load-bearing capacity, impact resistant, and adaptable to heavy loads, and are therefore widely used in the Gearboxes, drive shafts, conveying equipment, general machinery.

The 22213E/C3 Double-row spherical roller bearings mainly consist of an inner ring, an outer ring, two rows of spherical rollers, a cage, and seals. The outer ring raceway has a spherical structure, while the inner ring has a double-row raceway. The rollers and raceways are logarithmically curved. The cage is typically made of stamped steel or machined brass.
Double-row spherical roller bearings possess excellent self-aligning properties, compensating for shaft deflection, installation errors, and misalignment. They can simultaneously withstand radial loads and bidirectional axial loads, exhibiting extremely high load-bearing capacity and strong impact resistance. Furthermore, the internal clearance can be optimized for vibration conditions, effectively reducing frictional temperature rise.
