Self-aligning ball bearings
Self aligning ball bearings are suitable for applications where misalignment can arise from errors in mounting or shaft deflection. The steel balls, cage, and inner ring can rotate freely at a certain angle, as it is stated that the bearings have self-aligning features. Accordingly, misalignment of the bearing shaft due to the machining and installation of the shaft and housing will be automatically adjusted.
Advantages of Self Aligning Ball Bearings
Have the lowest friction of all rolling bearings.
Run cooler even at high speeds.
Easy mounting and dismounting.
The permissible operating speed is not dependent on the common criteria like heat generation or cage stability and strength.
Features :
1. Self aligning ball bearings are principally provided with two rows of symmetrical spherical rollers and a common sphere raceway in out ring, the two inner ring raceways are included at an angle to the bearing axis
2.With good selfaligning ability and can operate when the shaft deflection under load or the shaft deflection under load or the shaft misaligning in mounting, and their permissible aligning angle is 1 to 2.5 degree
3. This type of bearings has heavy load carrying capacity and anti-impact ability, in addition to radial loads, they also can carry axial loads in two directions
4.In general, this type of bearings permits a low limiting speed.
