22340AMAT41A Double Row Spherical Roller Bearings, For Vibrating Screens
The 22340AMAT41A 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 22340AMAT41A bearing is a Double row spherical roller bearings with an inner diameter of 200 mm , an outer diameter of 420 mm, a width of 138 mm. GCr15, GCr15SiMn, SUJ2 rings, GCr15, SUJ2 rolling mlement. Its dynamic radial rated load is approximately 2079932 N, its static radial rated load is approximately 2799929 N. It uses C4 standard radial clearance, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
22340AMAT41A bearings 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 22340AMAT41A 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.
