69-0481-63 Nippon Seiko (NSK) Self-Aligning Roller Bearings 21311EA
Features
- This bearing has rollers with barrel-shaped rolling surfaces built between the inner ring with two rows of raceways and the outer ring with spherical raceways.
- The center of curvature of the outer ring raceway coincides with the bearing center, so it is aligned.
- If there is a deflection of the shaft or housing, or if there is a misalignment of the shaft center, it is automatically adjusted so that excessive force is not applied to the bearing.
- Radial and bidirectional axial loads can be applied.
- The large radial load capacity makes it suitable for applications subjected to heavy loads and impact loads.
