Description; Application - SKF EAZ 80/130 Serie Instrucciones De Uso

1. Description

The tool consists of a circular yoke on which six adjustable yokes are attached. All yokes
are made of laminated iron. Each yoke has an induction coil through which an alternating
current of 50/60 Hz is fed.
The yokes are pressed against the raceway of the inner ring to be removed.
The alternating magnetic ields between the yokes pass through the inner ring and
produce eddy currents which cause a rapid heating and expansion of the inner ring which
can then be easily dismounted. For remounting, TIH induction heaters with automatic
demagnetization are recommended.
