Application Fields

This 3.6KVA bearing heater is commonly used in:

Electric motor repair workshops

Gearbox and reducer maintenance

Pump and compressor servicing

Steel plant mechanical departments

Cement and mining equipment maintenance

It is especially suitable for on-site installation where oil bath heating is inconvenient or unsafe.

Heating Performance and Working Principle

The heater works based on electromagnetic induction. When a bearing is placed on the yoke, alternating magnetic flux generates eddy currents inside the metal, producing heat internally and uniformly.

Compared with traditional oil heating or gas flame heating:

Heating time is significantly reduced

No smoke or oil residue

Energy consumption is lower

Temperature is easier to control

After heating is completed, the machine automatically performs demagnetisation to reduce residual magnetism, protecting bearing performance during operation.

Operational Advantages

Portable structure suitable for field maintenance

Adjustable temperature and time control modes

Uniform heating to protect surface hardness

Automatic demagnetisation after heating

Air-cooled system, no need for water cooling

Suitable for continuous workshop use

The compact design allows flexible movement between maintenance stations.
