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 fields 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.

2. Application

The heaters are used for dismounting of the various sizes of cylindrical bearing inner rings
types NU, NJ and NUP mounted on a shaft with an interference fit up to n6.

80 up to 130 mm (EAZ 80/130) and one for 130 up to 170 mm (EAZ 130/170).
