It can be categorized into cart-type bearing inner sleeve disassembly heaters and handheld bearing inner sleeve removers based on different methods, depending on the workshop space and operational convenience. Widely used in industries such as steel metallurgy and railway locomotives. Welcome customers to inquire at 13915895996.

● Bearing Inner Race Disassembly Heater (Mill Bearing Heater) Application: The GJT30J Bearing Inner Race Disassembly Heater (abbreviated as Bearing Inner Race Disassembly and Assembly Heater) is used for the installation and removal of inner sleeves and labyrinth rings of four-row and double-row short cylindrical roller bearings.

● Bearing Inner Race Disassembly Heater (Mill Bearing Heater) Working Principle: The GJT30J Bearing Inner Race Disassembly and Assembly Heater utilizes electromagnetic induction heating to uniformly heat the bearing inner sleeve and labyrinth ring from the surface inward, causing instantaneous thermal expansion. When the expansion of the inner hole exceeds the interference fit with the shaft diameter, the bearing inner sleeve or labyrinth ring can be easily removed or installed.

● Bearing Inner Race Disassembly Heater (Mill Bearing Heater) Structural Features: The GJT30J Bearing Inner Race Disassembly Heater consists of an induction heater main unit and a control box.

1. The induction heater is primarily composed of an electromagnetic coil and a stainless steel and epoxy board housing. When the induction heater operates continuously and the electromagnetic coil generates heat, a fan can be used to blow air onto the main unit coil for forced cooling, thereby extending the service life of the inductor. The induction heater is available in portable handheld and center-height adjustable models (users are advised to fabricate a simple support frame based on the workspace convenience and the roller's center height from the ground).

2. The control box primarily regulates the heating time for the inductor during the disassembly and assembly of the bearing inner race. It uses time control, stopping the heater when the set time elapses. Additionally, the control system is equipped with self-healing compensation capacitors to improve the power factor of the inductor and provide instant demagnetization (0.4-2 seconds). A portable thermometer is also included for users to measure temperature and its correlation with time.

Different specifications of bearing inner sleeves require corresponding bearing inner race disassembly heaters. It is strictly prohibited to heat bearing inner sleeves of different specifications in the same disassembly heater!
