Description:
Self-aligning ball bearings are constructed with the inner ring and ball assembly contained within an outer ring that has a spherical raceway. This construction allows the bearing to tolerate a small angular misalignment resulting from deflection or improper mounting. Self-aligning ball bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing.
This kind of ball bearings are particularly suitable for applications where considerable shaft deflections or misalignment are to be expected. Additionally, the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds.
Competitive Advantage
1. Quality level: reach the same level as the Japanese and European bearings
2. Tolerance level: ABEC-1 (P0), ABEC-3 (P6)
3. Less coefficient of friction
4. High limiting speed
5. Large size range
6. variations of structure
