Plate Bearing Heaters
Conductive plate heaters for controlled preheating of small bearings and other suitable workpieces.
Removal & Maintenance
Bearing Heaters
ToughTorq bearing heaters provide controlled thermal expansion for bearing installation and rotating-equipment maintenance. Plate heaters use conductive heating for small components, while KHG induction heaters provide direct electromagnetic heating with temperature and timing control, automatic heat preservation, demagnetization, and overheat protection.

Plate Bearing Heaters
Conductive plate-heater specifications
Plate heaters are designed for controlled preheating of smaller bearings and suitable components. The integrated heating surface can heat multiple workpieces within the available plate area.
| Model | Voltage | Power | Temperature Range | Control Accuracy | Plate Size | Overall Size | Weight |
|---|---|---|---|---|---|---|---|
| KHG-12 | 220 V | 1.32 kW | 60–320 °C | ±3 °C | 390 × 190 mm | 400 × 220 × 145 mm | 14.3 lb |
| KHG-12P | 110/220 V | 1.32 kW | 30–350 °C | ±3 °C | 390 × 190 mm | 400 × 220 × 145 mm | 15 lb |
Bearing Induction Heaters
KHG Series induction-heater specifications
KHG induction heaters use electromagnetic induction to heat the workpiece directly. The series supports constant-temperature and timed heating, automatic heat preservation, manual/automatic demagnetization, and overheat protection.
