22356-E1A-XL-K-MB1-C3 bearings ( 280 mm x 580 mm x 175 mm) 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 22356-E1A-XL-K-MB1-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.
