2. Introduction
The TMBH 5 portable induction heater is designed
to heat up roller bearings that are mounted with an
interference fit onto a shaft.
Other ring-shaped metallic components can also be
heated.
The heat causes the bearing to expand, which
eliminates the need to use force during installation.
A 90 °C (162 °F) temperature difference between
the bearing and shaft is generally sufficient to
enable the installation.
At ambient temperature of 20 °C (68 °F) the bearing
must be heated to 110 °C (230 °F).
Shielded bearings or sealed bearings with metallic
insertions must be controlled as the shield or
the metallic insert might heat much faster than
the bearing itself. A reduced power setting is
recommended in these cases.
