2 - As a guideline, install the bearing shell with
the greatest interference first. Smaller
bearings with only a small degree of assembly
interference may be seated by tapping gently
into place using a mallet and a soft punch
or, preferably, a piece of pipe placed with
its end against the circumference of the
bearing shell. Tap uniformly around the entire
circumference of the bearing shell to ensure
that it remains perfectly perpendicular
relative to its seat. The cup tool illustrated
in Fig. 1.16 ensures that force is applied
perfectly perpendicularly and distributed
evenly around the entire circumference of
the bearing shell. Mechanical or hydraulic
presses are generally used to install bearings
on the production line.
3 - When
installing
bearing on the shaft and in its respective seat
simultaneously, place a disc (Fig. ) between
the bearing and the tubular tool to distribute
the installation force even more evenly over
the circumferences of the two bearing
shells. This method is recommended in
particular for swivelling bearings to prevent
misalignment of the outer shell relative to
the seat. As a alternative, a cup tool with two
contact surfaces (one for the inner shell and
one for the outer shell) may be used (Fig. ):
these two surfaces must be coplanar.
4 - The inner and outer shells of disassemblable
bearings may be installed separately. this
significantly facilitates assembly, especially
in cases where both shells must be forced
into their seats. When mating two parts of
a bearing that have already been installed
in their seats, ensure that the two rings
of
rotating
bearing
perpendicularly aligned, as the bearing races
may be damaged if they are misaligned.
