Users usually have some questions when buying our company's "Zhuangyuan brand" bearing induction heater: will it damage the bearing? The reply is as follows: 

1、 Why do you have to use a bearing heater

There are some problems in the installation of bearings by traditional heating methods, such as oil bath, electric furnace heating and flame heating

a. It is time-consuming and laborious, with high work intensity and high loss

b. The initial lubrication state of the bearing itself is destroyed, which is easy to cause accidents.

c. Heating temperature can not be controlled, usually due to high temperature caused by bearing annealing

d. Uneven heating causes deformation and damage of bearing

e. Closed bearings cannot be heated

At present, the international common bearing installation method is interference hot sleeve assembly, "Zhuangyuan" brand bearing heater solves the above problems, completely changes the assembly mode, and makes the bearing which is difficult to install easy!

2、 Working principle of bearing heating machine

Using alternating current to produce alternating magnetic field, and then using alternating magnetic field to produce eddy current, so that the metal workpiece is heated rapidly. Therefore, bearing heating is also called induction heating.

In the heating process, only the metal part of the workpiece is heated, and the heater itself and the non-metal part of the workpiece (sealing ring, lubricant, etc.) are not heated. Therefore, the bearing heater can be used to heat the sealed bearing and the pre lubricated bearing. All closed metal workpieces can be heated by (bearing) heater, such as bearing, gear, pulley, coupling, coupling, coupling, dust cover, piston, etc. in short, as long as the metal object can be penetrated by the heating rod, it can be heated by (bearing) induction heating.

Zhuangyuan brand bearing induction heaters are equipped with automatic degaussing function to reduce the residual magnetism of the heated workpiece< 2A/cm ，fully meet the installation of all pipelines.
