For bearing arrangements where the load carrying capacity of a single tapered roller bearing is inadequate, or where the shaft has to be axially located in both directions with a given positive or
negative axial play, the bearings listed in the section “Single row tapered roller bearings“, can be supplied as matched pairs arranged

-  face-to-face

-  back-to-back

-  in tandem

Matched paires bearings resolve many problems about bearing arrangement economically. The followings are all their advantages:

-  easy mouting, no need to adjust the space ring, so as to advoid mouting error

-  precise axial orientation, decide the clearance during manufacturing

-  large carrying capacity of both axial loads and radial loads

-  easy maintenance, add lubricant through the ring groove on the space ring or grease hole
