1. Self-aligning Ball Bearings with Low Friction
2. It has two rows of balls and a common concave sphered raceway in the outer ring.
3. Onsequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing.
4. Suitable for applications where considerable shaft deflections or misalignment are to be expected.
5. Has the lowest friction of all rolling bearings
