WS22222-E1-K-2RSR-C3 Sealed Spherical Roller Bearings, Symmetric With Cage Guidance Ring
The WS22222-E1-K-2RSR-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 WS22222-E1-K-2RSR-C3 bearing is a Sealed Spherical Roller Bearings, symmetric with cage guidance ring with an inner diameter of 110 mm , an outer diameter of 200 mm, a width of 63 mm. GCr15, GCr15SiMn, SUJ2 rings, GCr15, SUJ2 rolling mlement. Its dynamic radial rated load is approximately 549850 N, its static radial rated load is approximately 599849 N. It uses C3 standard radial clearance, 2RSR = Seals on both sides, normal temperature type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
WS22222-E1-K-2RSR-C3 bearings ( 110 mm x 200 mm x 63 mm) have the advantages of Self-aligning, high load-bearing capacity, and impact resistant, and are therefore widely used in the Mining machinery, metallurgical equipment, papermaking machinery, vibrating screens, wind turbines, and large industrial gearboxes.

The WS22222-E1-K-2RSR-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.
