Heating method: It is recommended to use induction heater heating method, which is even, efficient and clean.

Oil heating method:

1. Do not heat the bearings above 120°C.

2. In order to avoid direct contact with the bottom of the oil tank, place the bearing on a metal mesh or hang it.

3. In order to avoid installation difficulties caused by cooling of the inner ring during operation, the bearing can be heated 20°C to 30°C higher than the required temperature.

4. After cooling down after installation, there will be axial shrinkage. In order to avoid a gap between the inner ring and the shaft shoulder, the nut on the shaft or other appropriate methods can be used to tighten it.
