Relubrication via the outer ring
The hole closest to the cover should be used to
relubricate spherical roller bearings with a
relubrication feature (a lubrication groove and
holes in the outer ring) († fig. 11). When 11
applying grease via the relubrication feature
the shaft should be rotating.

Relubrication from the side
When relubricating from the side, which is
typically necessary for self-aligning ball bear-
ings and CARB toroidal roller bearings, the
hole closest to the flange should be used
(† fig. 12).
FNL flanged housings have an integral
flange that guides grease from the grease fit-
ting directly to the rolling elements
(† fig. 13).
