Angular contact ball bearings can support radial and axial load at the same time, single row angular contact ball bearing only support single-direction axial load, therefore they are normally matched in pairs for application. If matched in pairs, the preloaded angular contact ball bearings are the most convenient.
Single row angular contact bearing with back to back matching arrangement can carry axial load from two directions, Meanwhile, it can carry radial load.
The inner ring is separable, can carry two-direction axial load.
