SKF TIH L77/MV Extra Large Induction Heater

The SKF TIH L series heaters are designed for induction heating of large size rolling bearings. With advanced power electronics and an effective dual coil design, the TIH L series can heat large bearings weighing up to 1200 kg (2600 lb), using just 20 kVA of electrical power. This represents a power saving of almost 50% compared to similar induction heaters and highlights how SKF Induction Heaters are simultaneously powerful and efficient. Unusually for a bearing heater for large bearings, the TIH L series can be supplied in medium and low voltage versions.

The SKF TIH L induction heater is designed to heat bearings, which are mounted with an interference fit onto a shaft. 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 installation. At an ambient temperature of 20 °C (68 °F), the bearing must therefore be heated to 110 °C (230 °F).
