Bearing heaters operate on the principle of electromagnetic induction. Alternating current passing through coils inside the device creates a magnetic field. This magnetic field produces eddy currents on the bearing. These currents turn into heat due to the metal's own resistance, and the bearing heats up directly from within.

This method provides controlled and homogeneous heating without using open flames or ovens. Thus, the inner diameter of the bearing expands, allowing for installation without damaging the shaft.

For your safety, read the user manual. Danger of cardiac arrest for people with pacemakers due to the strong electromagnetic field! Serious burns can occur on hands as a result of touching hot material without protective gloves!

1. Connect the power cable to a suitable power source.

2. Turn the power switch to the ON position.

3. Place the bearing or workpiece. If it is large enough, put it in the turbo section. Make sure the yoke is positioned correctly.

4. Connect the temperature sensor to the socket on the device. Attach the magnetic sensor tip to the inner ring of the bearing.

5. Select the mode by touching the touch screen. Adjust the temperature, time, and power as needed.

6. Press the button or touch the screen to start heating.

7. When the heating process is complete, the device will give an audible warning.

8. Put on your gloves, remove the magnet and the yoke.

9. Place the bearing on the workpiece without wasting time.

Model selection depends on three basic criteria:

• Diameter of the bearing to be heated

• Weight of the bearing

• Frequency of the heating process

Additionally, power supply (220V / 380V), portability needs, and the workshop environment are decisive factors. Choosing the right capacity is important for energy efficiency and heating time. A device larger than necessary increases investment costs and works inefficiently with small bearings at the lower limit of capacity, while a small device leads to performance loss.

You can find the technical data of that product on the product pages. If you are still undecided, we are happy to help.

In induction systems, heat is generated directly within the bearing. Therefore, the body of the device does not heat up intensively. However, there may be heating in the core and some contact surfaces during operation.

Heating time depends on the size, weight of the bearing, and the target temperature. Small bearings can heat up in a few minutes, while in large and heavy bearings this time can take up to 15–20 minutes.

Induction systems provide much faster and more controlled results compared to traditional ovens or oil baths.

Of course. In addition to bearings, you can heat all closed-circuit conductors such as gears, pulleys, and rings in your device.
