Single Row Externally Aligning Ball Bearing
The Single Row Externally Aligning ball bearings are used where accurate alignment cannot be ensured between bearing positions. This bearing type can mainly take radial loads. Axial loads can also be accommodated.
The shell housing must not be made an interference fit on their outside diameter. If an interference fit is used, the shell housing may contract and prevent alignment. These bearings can be located endwise in both the directions.
Double Row Self Aligning BalI Bearing
The Double Row Self-Aligning ball bearings have a common outer spherical race for both the rows. This feature gives the bearings self-aligning properties. The bearings have the same external dimensions as their equivalent single row radial ball bearings. They can take radial loads and very light axial loads. They can be located endwise in both directions.
Double Row Self-Aligning Ball Bearing with Tapered Clamping Sleeve and Nut
The Double Row Self-Aligning ball bearings with Tapered Clamping Sleeve and Nut, are identical to Double Row Self-Aligning ball bearings except that these have a tapered bore, which is used for easier mounting and also a clamping sleeve and nut to clamp the bearings on the shaft. The tapered bore is also used for the adjustment of radial clearance.
