I. Purpose of the Bearing Heater

　　The GJT30 Bearing Heater is mainly used for heating bearings and ring-type metal parts to cause expansion, meeting the needs of interference fit assembly or disassembly.

II. Structure and Working Principle of the Bearing Heater

● Structure of the Bearing Heater 　　The GJT30 Bearing Heater consists of a dry self-cooled power frequency induction heating device (hereinafter referred to as the main unit) and control equipment.

● Working Principle of the Bearing Heater

　　 1. Short-Circuit Heating: The main unit is a specially structured transformer, with a movable yoke used to directly sleeve bearings or other workpieces to be heated. During operation, when the main unit is powered on, a short-circuit current is induced in the workpiece (equivalent to the secondary winding), causing it to heat up.

　　 2. Eddy Current Heating: The heated workpiece and the main unit's iron core form a closed magnetic circuit. During operation, the magnetic flux from the main unit generates eddy currents in the workpiece, resulting in rapid heating.

III. Features of the Bearing Heater　The GJT30 Bearing Heater has the following distinct advantages:

● Improved Efficiency: Work efficiency is increased by more than 4 times, and the number of operators is reduced by 80%;

● Reduced Costs: Electricity savings of over 70%, 100% oil savings, and over 60% savings in factory floor space;

● Environmental Protection: No oil pollution in the air, contributing to environmental improvement and the health of workers.

● Enhanced Quality: Uniform heating, clean workpiece surface, unchanged hardness, and automatic demagnetization meeting industry standards;

● Reliable Operation: Easy and safe operation, extremely low equipment failure rate, 18-month warranty on the main unit, and insulation up to Class B;
