22332MB Double Row Spherical Roller Bearings
The 22332MB 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 22332MB bearing is a Double row spherical roller bearings with an inner diameter of 160 mm , an outer diameter of 340 mm, a width of 114 mm. GCr15, GCr15SiMn, SUJ2 rings, GCr15, SUJ2 rolling mlement. Its dynamic radial rated load is approximately 1429915 N, its static radial rated load is approximately 1899914 N. It uses CN standard radial clearance, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
22332MB bearings have the advantages of Self-aligning, extremely strong load-bearing capacity, and impact resistant, and are therefore widely used in the Heavy-duty speed reducers, low-speed rolling mills, and medium-sized mining equipment.

The 22332MB 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.
