Types of self-aligning ball bearings

wallpapers Tech 2020-05-26
The self-aligning ball bearing has two rows of balls, the outer ring has a common spherical raceway, and the inner ring has two deep unbroken raceway grooves. They are open or sealed. The bearings are not sensitive to angular misalignment of the shaft relative to the housing, which may be caused by shaft deflection, for example.

Self-aligning ball bearings can be divided into several types according to their structures and features:
Single row external aligning ball bearings
Single-row external aligning ball bearings are used where precise alignment between bearing positions cannot be ensured. This bearing type mainly bears radial load. Can also bear axial load.
The shell must not have an interference fit on its outer diameter. If an interference fit is used, the housing may shrink and prevent alignment. These bearings can be positioned in both directions.
Double row self-aligning BalI bearings
Both rows of double row self-aligning ball bearings have a common outer spherical seat ring. This function makes the bearing have self-aligning performance. The external dimensions of the bearing are the same as their equivalent single-row radial ball bearings. They can withstand radial loads and small axial loads. They can be at the end in both directions.
Double row self-aligning ball bearing with conical clamping sleeve and nut
Double-row self-aligning ball bearings with conical clamping sleeves and nuts are the same as double-row self-aligning ball bearings except that they have tapered holes that simplify installation and provide protection The clamping sleeve and nut are on the shaft. Tapered holes can also be used to adjust radial clearance.
