Mounting, dismounting and bearing care
Dismounting bearings fitted on an
adapter sleeve
Small bearings fitted on an adapter sleeve and
a plain shaft can be dismounted by tapping a
small steel block with an appropriate hammer
evenly around the bearing inner ring side face
(† fig. 31). Before doing so, the sleeve lock
nut has to be loosened a few turns.
Small bearings fitted on an adapter sleeve
and a stepped shaft can be dismounted by a
couple of sharp hammer blows applied to a
dolly abutting the sleeve lock nut († fig. 32).
Before doing so, the sleeve lock nut has to be
loosened a few turns.
Using a hydraulic nut for dismounting bearings
fitted on an adapter sleeve and a stepped
shaft makes bearing removal easy. To use this
method however, it must be possible to mount
a suitable stop that abuts to the piston of the
hydraulic nut († fig. 33). If the sleeves are
provided with oil supply ducts and distribution
grooves, dismounting becomes easier because
the oil injection method can be used.
