Working Principle
The induction bearing heater generates alternating magnetic field through internal enclosed induction coils. Eddy current is produced inside metal ferrous workpieces such as bearings, generating internal heat rapidly. Workpiece heats itself without open flame. Temperature and heating time can be precisely set, avoiding local over‑heating that damages bearing internal structure and original precision.
Product Series Introduction
Galaxy Machinery supplies complete series of induction bearing heaters, covering small desktop models M25T/M36T/M50T/M80T/M100T, compact M35H / M60H and heavy‑duty floor‑standing M80H‑M250H series.
M25T‑M100T Series: Compact table‑top structure, suitable for small‑to‑medium bearings. Simple operation, ideal for daily workshop maintenance.
M35H / M60H Series: Three groups fully enclosed induction coils, high heating efficiency. High‑temperature resistant epoxy resin potting, cylindrical thermal expansion design delivers more uniform heating effect. Support bearings with sealing rings and pre‑lubricated bearings.
M80H‑M250H Heavy‑Duty Series: 304 stainless steel housing, anti‑magnetic design, double solid main frame. Large‑size models handle heavy bearings up to 600 mm inner diameter. Mobile wheel design enables flexible on‑site operation for heavy‑duty plant overhaul.
Core Advantages & Key Features
Stepless power adjustment: Match heating power according to workpiece size.
Wide compatibility: Can heat sealed bearings and bearings pre‑filled with lubricant.
Dual control mode: Adjustable heating time 0‑9999 seconds and max temperature up to 300℃. Real‑time digital display, fault code alarm and overload protection ensure operational safety.

Typical Application Scenarios
Mechanical maintenance workshop: Bearing disassembly & installation for motors, reducers, pumps
Heavy‑industry manufacturing: Mining equipment, wind power, metallurgy, railway machinery assembly
Repair service center: Interference fit heating for bearings, gears, bushings, sleeves, pulleys
Production line: Batch thermal assembly of ferrous metal ring‑shaped parts
Operation & Safety Tips
Only heat ferromagnetic metal workpieces; do not heat non‑ferrous materials.
Do not exceed the rated maximum temperature of 300℃, excessive high temperature will destroy bearing hardness and precision.
Fault code display function helps operators quickly locate abnormal conditions. Overload protection avoids equipment burnout.
For sealed pre‑greased bearings, strictly follow recommended heating temperature to prevent grease deterioration.
