Matched bearings arranged face-to-face have load lines that converge toward the bearing axis. Therefore, the arrangement can accommodate a limited amount of misalignment. Axial loads in both directions can be accommodated, but only by one bearing in each direction .The bearing set is supplied with an intermediate outer ring spacer. The suffix DF means two bearings matched for mounting face-to-face. A number immediately following the DF identifies the design of the ring spacer.
