Why is a taper roller bearing used in pairs? - Quora

Tapered bearings, be they roller or ball bearoings with tapered cages, are asymmetrical: they can support an axial load very well in one direction, less well in the opposite direction. If you don’t know what direction the axial load will take, then you’d better put the tapered bearings in pairs with one bearing opposed to the other.
