Power Level Selection; Safety Features - SKF TIH 100m Mode D'emploi

5.8 Power level selection

When heating bearings with an induction heater, most of the heat will be generated in the
inner bearing race. The heat will then be transferred through the bearing. It is therefore
important that bearings with reduced internal clearance are heated slowly. Slow heating
ensures that the bearing expands evenly, thereby preventing damage to the bearing.
The shape, weight, size, and internal clearances all affect the amount of time required to
heat a bearing. The large variety of bearing types precludes the possibility of providing a
speciic power level setting for each type. Instead, the following guidelines are provided:
• "For sensitive bearings (including bearings with C1 or C2 internal clearance) or
bearings with brass cages, preferably use 50% power.
• "When using the small yoke, never exceed 50% power.

6. Safety features

The TIH 100m is equipped with the following safety features:
• "Automatic overheating protection
• "Automatic current control
• "Over-current circuit breaker.
• "In the TEMP MODE the heater will switch off if the temperature probe does not
register a temperature increase of 1 °C (1.8 °F) every 15 seconds (0.25 minute).
To increase the interval to 30 seconds (0.50 minute), press MODE and DOWN at the
same time.
