Induction heaters for non-bearing applications

TIH L MB series

Induction heaters for non-bearing applications TIH L MB series
The TIH L MB heats non-bearing workpieces
The TIH L MB heats non-bearing workpieces up to 600 kg (1 323 lb), depending on the model.

The induction heaters TIH L MB are specially designed to heat solid workpieces such as rings, sleeves, gears, couplings, bushings and pulleys, as well as train wheels, tires or similar components. Featuring one magnetic coil in the center, these powerful and durable heaters localize the heating in the workpiece bore for superior performance on solid components. 

  • The TIH L MB series provides the following advantages for quick and effective heating of solid workpieces:
  • Simple and safe operation with remote-control and power level selection
  • Superior heating performance for solid workpieces with low energy consumption
  • Quick and easy placement of solid components with sliding yoke
  • Automatic demagnetization reduces risk of ferrous debris contamination
  • Easy handling and transport with standard forklift

Advice: The TIH L MB series heaters are designed for induction heating of solid, non-bearing components. For bearing-heating applications, we recommend the use of equivalent TIH L series heaters.
