3. Description
The operation of the heater is controlled by the
internal electronics in two modes.
The operator can either select the desired
temperature of the bearing in Temperature Mode or
set the length of time that the bearing or component
will be heated in Time Mode. The power level can be
adjusted to Low Power Mode for slower heating
of sensitive workpieces (for example, bearings with
shields or metallic inserts in the seals).

1) SKF does not recommend heating bearings capped with seals or shields above 80 °C (175 °F).
However, if higher temperatures are necessary, please contact SKF.
The heater is designed for maintenance operations where some cooling in between jobs is allowed.
2) Depending on the geometry of the bearing, maximum heating temperature.
4. Installation
Make sure that the line voltage is within the
specified range depending on the heater type.
I M P O R TA N T:
The main switch in the heater is not a safety
switch. The heater needs to be unplugged from the
mains to perform any repair. If the mains cable is
damaged, it must be replaced.
