The 22220-E1A-K-M-C4 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.
