22320 CCK/W33 VA405 Bore 100 Mm, Stamped Steel Cages, Spherical Roller Bearings, For Vibratory Applications, Surface-hardened
The 22320 CCK/W33 VA405 Spherical roller bearings are suitable for harsh working conditions with high humidity, dust, and strong vibration and impact. Classic applications include vibrating screen exciters, crushers, vibrating motors, vibrating rollers, mining vibrating machinery, and saw frames, among other vibrating equipment.
The 22320 CCK/W33 VA405 bearing is a Spherical roller bearings, double row with an inner diameter of 100 mm , an outer diameter of 215 mm, a width of 73 mm. GCr15SiMn rings, GCr15SiMn rolling mlement. It uses C4 standard radial clearance, Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
22320 CCK/W33 VA405 bearings ( 100 mm x 215 mm x 73 mm) have the advantages of Vibration resistant, impact resistant, high temperature resistant, self-aligning, and are therefore widely used in the Heavy-duty vibrating screens for mining, metallurgy, construction, and coal industries..

The 22320 CCK/W33 VA405 Spherical roller bearings mainly consist of an inner ring, an outer ring, two rows of drum-shaped rollers, and a cage. The outer ring raceway has a spherical structure, while the inner ring has a double-row raceway. The cage is typically a machined brass or stamped steel solid structure guided by the outer ring to adapt to high-frequency vibration conditions.
Spherical roller bearings possess self-aligning properties, compensating for shaft deflection and installation misalignment. They can simultaneously withstand radial and bidirectional axial loads, exhibiting high load-bearing capacity and strong impact resistance. Furthermore, their internal clearance and cage guidance method are optimized for vibration conditions, effectively reducing frictional temperature rise.
