EDDYTHERM - Professional induction bearing heaters: Fast, easy and reliable

Product catalog summary

Introduction
EDDYTHERM® Professional Induction Bearing Heaters are designed to extend the life of roller bearings through proper shrink fitting. Improper installation is a major cause of reduced bearing life, and EDDYTHERM® offers a solution through controlled heating.

Why Shrink Fitting?
Shrink fitting extends bearing life by avoiding damage from mechanical installation methods. EDDYTHERM® uses induction heating, which is safer and more effective.

The Process
EDDYTHERM® operates on the induction principle, heating the workpiece by acting as a short-circuited secondary winding. This allows for precise temperature control and even heating, while the heater remains cool.

Advantages

Robust Design: Suitable for workshop use with heavy-duty construction.
Environmentally Friendly: Energy-saving with no smoke or oil vapour.
Safety: Features automatic error detection and thermal overload protection.
Bearing Preservation: Maintains factory prelubrication and prevents damage from vibration.

Extend bearing life with proper shrink fitting 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 heating. The process 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,...
