The 29396EM Spherical Roller Thrust Bearings primarily consist of a shaft ring, a housing ring, asymmetrical drum-shaped rollers, and a cage assembly. The housing ring features a spherical raceway design, allowing the rollers to automatically adjust for alignment errors between the shaft and the housing ring.

The advantages of Spherical Roller Thrust Bearings lie in their superior self-aligning capability, effectively compensating for misalignment caused by installation skew or shaft deformation. They also possess extremely high axial load capacity, can withstand certain radial loads, and exhibit excellent impact resistance.
