INTRODUCTION
Also analyze the state of the cage (4) .
If everything is in order, make a noise test (3) when rotat-
ing the bearing with the hands, it cannot present metallic
noises and its spinning must be completely smooth.
The slightest irregularity in any of the above determines
the replacement of the bearing.

For installation
• Never install a bearing applying direct hammer blows
on it!
• Prefer the use of presses for installing bearings. For
field installations, a hammer can be used, however, the
bearing needs to be displaced in an aligned manner by
an appropriate tool.
• Lubricate the bearings before or after their installation.
NOTICE: The force to install the bearing should only
be applied on the track (internal or external) which is
installed with interference.
NOTICE: If the force (of the press or the hammer blows)
is applied on the free track, the balls and cages of the
bearing could suffer serious damage.
• So to install bearings in holes, press the outer ring, and
to install bearings on shafts, press the inner ring.
• For the installation with both a press or a hammer, the
bearing must be lying on a flat, firm surface and per-
pendicular to the tool or press used in the installation.
