Professional Induction Heater for Bearing Maintenance and Assembly
Operating Principle & Superiority: This equipment utilizes high-frequency electromagnetic induction to heat metal workpieces from the inside out. Unlike traditional oil baths, it provides uniform thermal expansion, preventing localized overheating and ensuring the metallurgical integrity of high-precision bearings.
Safety & Compliance: Designed with operator safety in mind, it features a fully enclosed insulated coil and automatic overheat protection. It complies with international safety standards, ensuring zero oil smoke and a cleaner workshop environment.
Precision Control System: Equipped with a microcomputer-controlled interface, it allows for "dual-mode" operation: Temperature Control (0-300°C) and Time Control (0-999s). This ensures repeatable accuracy for high-volume assembly lines.
Advanced Demagnetization: Residual magnetism in bearings can attract metal debris, causing premature failure. Our technology ensures automatic demagnetization to <2A/CM, exceeding international industrial standards.
Trusted Global Partner: WTR is a verified supplier for Fortune 500 companies including ABB, Siemens, and CRRC, ensuring world-class reliability for your maintenance needs.

FAQ
Q: Does this heater damage the lubrication of sealed bearings?
A: No. The electromagnetic induction heats the metal ring directly and uniformly. Because the heating time is short and the temperature is precisely controlled, it does not damage the bearings.
Q: How do I know when the heating process is complete?
A: The device features an audible signal and automatic stop function. Once the preset temperature or time is reached, the heater stops and automatically begins the demagnetization process for safe handling.
