I. Purpose of the Bearing Heater

　　The GJT30 Bearing Heater is primarily 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-cooling 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, the main unit is powered on, and the workpiece (equivalent to the secondary winding) induces a short-circuit current and is heated.

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

III. Features of the Bearing Heater　The GJT30 Bearing Heater offers the following significant advantages:　　

● Improved Efficiency: Work efficiency increases by more than 4 times, and the number of operators is reduced by 80%; ● Cost Reduction: Saves over 70% in electricity, 100% in oil, and reduces workshop space by more than 60%;　　

● 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 for the main unit, and insulation up to Class B;
