WS22218-E1-2VSR Sealed Spherical Roller Bearings, Symmetric With Cage Guidance Ring
The WS22218-E1-2VSR 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 WS22218-E1-2VSR bearing is a Sealed Spherical Roller Bearings, symmetric with cage guidance ring with an inner diameter of 90 mm , an outer diameter of 160 mm, a width of 48 mm. GCr15, GCr15SiMn, SUJ2 rings, GCr15, SUJ2 rolling mlement. Its dynamic radial rated load is approximately 344801 N, its static radial rated load is approximately 374850 N. It uses CN standard radial clearance, 2VSR = Seals on both sides, high temperature type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
WS22218-E1-2VSR bearings 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 WS22218-E1-2VSR 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.
