Description SKF bearing heaters use the principle of electrical induction to generate heat. It is basicly done by putting the bearing as the secondary coil on a type of transformer. The primary coil, with a large number of windings, is then connected to high voltage, causing a low current to pass through the coil. This will create a magnetic field flowing through the mutual iron core, inducing low voltage and a very high current in the bearing. The electrical resistance of the bearing will thus cause it to heat rapidly. TIH 025 consists of a housing, three top yokes and a yoke tray. Maximum power consumption is 3,5 kVA. In order to provide highest possible efficiency a special power limitation device has been built in. The TIH 025 is provided with a main switch and the heating cycle can be monitored by means of a timer (0 - 15 minutes).

Safety

• Since a magnetic field is generated by the bearing heaters, people wearing a pacemaker should not work with or be in the immediate vincinity of the apparatus.
• The bearing heater should not be used in areas where there is a risk of explosion.
