matched bearings
When matched tapered roller bearings,
arranged face-to-face or back-to-back, are
mounted together with a third bearing, the
bearing arrangement is statically indetermin-
ate. In these cases, the radial load F acting
r
on the bearing pair must be calculated irst F r
Matched bearings arranged
face-to-face
For matched bearings, where two bearings
are arranged face-to-face (ig. 19), it can be
assumed that the radial load acts at the
geometric centre of the matched bearings,
as the distance between the pressure
centres of the two bearings is short when
compared with the distance between the
geometric centres of the set and the other
bearing In this case, it can be assumed that
the bearing arrangement is statically
determined
