Self-alignning Ball Bearing
The self-aligning ball bearing has two rows of balls and a common concave sphered raceway in the outer ring.
This kind of bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing. It is 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.
The self-aligning ball bearings are available in the following designs:
Open design
Sealed design
Open design with extended inner ring
