A comprehensive range for bearings and other workpieces
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 1 200 kg (2 600 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.
Advanced power electronics, with accurate electric current control, help control the temperature rate increase.
Using just 20 kVA of electrical power, the TIH L series can heat large bearings weighing up to 1 200 kg (2 600 lb).
Automatic demagnetisation reduces the risk of ferrous debris contamination after heating.
Thermal overheating protection reduces the risk of damage to the induction coil and the electronics, enhancing reliability and safety.
Available with three different operating areas.
Available in three voltage variants to suit most operating voltages worldwide.
Bearings can be heated vertically or horizontally.
