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.
