Large bearing heater with high heating capacity of up to 300 kg bearing
The
SKF large induction heater TIH 220m is a reliable and robust induction
heater from the SKF TIH...m range 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:
- Capable of heating a 220 kg (460 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
- 3 year warranty
SKF m20 concept
"m20"
represents the weight (kg) of the heaviest SRB 231 bearing which can be
heated from 20 to 110 °C (68 to 230 °F) in 20 minutes. This defines the
heater's power output instead of its power consumption.
