The self-aligning ball bearing has two ball rolling bodies, and the outer ring is provided with a common spherical raceway, and the inner ring is provided with two deep groove type continuous non breaking rollers. They can be open or sealed. This type of bearing allows for a larger angular displacement of the shaft relative to the bearing seat, for example, the angular displacement caused by the shaft deflection.
Bearing characteristics:
Able to adapt to static and dynamic misalignment
And spherical roller bearings or CARB bearings, the bearing also has self-aligning ability.
Excellent high speed performance
Compared with any other type of rolling bearings, self-aligning ball bearings have the lowest friction, even at high speeds.
Minimum maintenance requirements
Bearing temperature is low because of less heat, thereby extending the bearing life and maintenance interval.
Low friction
The clearance between the rolling element and the outer ring can reduce friction and friction heat.
Excellent light load performance
Self aligning ball bearings have lower minimum load requirements.
Small noise
For example, self-aligning ball bearings can reduce the noise and vibration level.
