The 22348-E1A-MA1-T41A 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.
