EDDYTHERM Portable

Category
Pruftechnik

High frequency technology for outstanding heating performance.

Proper shrink fitting extends the life of roller bearings by several times. EDDYTHERM Portable operates in the high-frequency range to heat roller bearings with an inner diameter as small as 20 mm up to an outer diameter of 160 mm and a weight of up to 10 kg.

The workpiece is placed onto the cone shaped heating surface. The integrated time and temperature regulation capability ensures that the workpiece is heated evenly with no risk of overheating.


Key features

  • Suitable for bearings up to 10 kg

  • Portable and compact induction heater

  • Magnetic temperature probe up to 180°C

  • No support yoke required

  • Predictive temperature control (no overheating)

  • Available options: Voltage from 100 – 230 V and frequency 50/60 Hz.

  • High frequency technology for outstanding heating performance

Additional Info

EDDYTHERM® is the logical approach to shrink fitting of bearings, gears, couplings, impellers, crane wheels, rings, sleeves, etc

EDDYTHERM® utilizes the induction principle as in transformers – its core and windings can be seen as the primary side, but the workpiece acts as a short-circuited secondary winding, which rapidly heats up due to its great electrical resistance.  This phenomenon allows EDDYTHERM® to control heating by continuously monitoring the workpiece temperature and adjusting its own heating power accordingly.  This ensures that the workpiece is heated evenly and the selected temperature is achieved precisely. The crossbar itself remains cool to touch.

Why shrink fitting?

Proper shrink fitting extends the life of roller bearings by several times. Nearly half of all reduced bearing life expectancy is due to improper installation. Mechanical methods such as hammers and hydraulic presses risk damaging the inside surface of the inner ring and the bearing races.  The better shrink fitting solution is via induction heating.
