SKF Large Induction Heater TIH-220m
The SKF large induction heater TIH-220m is a reliable and robust induction heater from the SKF TIH…m range. It is suitable for heating bearings up to a maximum weight of 300 kg (660 lbs) and solid components up to a maximum weight of 150 kg (330 lbs).
Advanced design of the power electronics including current and overheating control, combined with user friendly features such as sliding arms and remote control are standard to the TIH…m range.
Maximum efficiency is achieved by placing the induction coil outside the heater’s housing, in the centre of the bearing,resulting in shorter heating time and lower energy consumption.
The LED operating display and control panel are integrated in a remote control, which makes the heater easy to use. To suit different operating voltages worldwide, the TIH 220m is available in different voltage variants.
Features & benefits
- Capable of heating a 220 kg (480 lbs) bearing in just 20 minutes, saving time and energy
- Supplied standard with two yokes, allowing bearings with a bore diameter from 60 mm (2.3 in) up to a maximum weight of 300 kg (660 lbs) to be heated
- 2-step power setting and smaller yoke facilitates efficient heating of smaller bearings with a lower power consumption
- Temperature mode pre-set at 110 °C (230 °F), helps prevent bearing overheating
- Automatic demagnetisation
Foldable bearing support arms allow larger diameter bearings to be heated, and reduce the risk of the bearing toppling during heating.
Capable of heating a 220 kg (480 lbs) bearing in just 20 minutes.
