* Permissible B clearances for standard radial bearings. If the clearances
measured on TPS57 or TPS61 are outside the permissible range, this can
indicate radial bearings with a special bearing geometry. Different permis-
sible values are valid for radial bearings with a special bearing geometry
(see the table below).
