Safety recommendations
• Because the IH 070/090 generates a magnetic field,
people wearing a pacemaker must not be within 5m (16ft) of the
IH 070/090 during operation. Electronic equipment,
such as wristwatches, may also be affected.
• Follow the operating instructions at all times.
• Be certain that the voltage supply is correct.
• Electrical arcing may occur when a potential difference exists
between the IH 070/090 and the workpiece. This is not
dangerous to human beings and will not cause damage to the
IH 070/090 or the workpiece. However, the IH 070/090 must
never be used in areas where there is a risk of explosion.
• Do not expose the heater to high humidity.
• Never operate the IH 070/090 without a yoke in
position.
• Do not modify the IH 070/090.
• Use proper handling equipment when lifting heavy workpieces.
• Avoid contact with hot workpieces. Wear the supplied heatresistant
gloves to handle hot workpieces.

1 Introduction
The simatec IH 070/090 induction heater is designed to heat bearings that
are mounted with an interference fit onto a shaft. The heat causes the bea-
ring to expand, which eliminates the need to use force during installation. A
90°C (194°F) temperature difference between the bearing and shaft is ge-
nerally sufficient to enable installation. At an ambient temperature of 20°C
(68°F), the bearing must therefore be heated to 110°C (230°F).
1.1 Intended use
The IH 070/090 has been designed to heat rolling bearings. However, other
metal workpieces that form a closed circuit can also be heated. Examples
of acceptable workpieces include bushings, shrink rings, pulleys, and gears.
All bearings that fit over the inductive coil and between the vertical supports
with the top yoke in place can be heated using the IH 070/090. In addition,
smaller bearings can be placed over either of the three standard yokes. See
the illustrations at the beginning of this manual for examples.
1.2 Principle of operation
The IH 070/090 generates heat by me-
ans of a large electrical current that is
magnetically induced in the workpiece
by a coil within the
heater. The high voltage, low current
electricity flowing through the large
number of windings in the inductive
coil induces low voltage, high current
electricity in the workpiece. Because the
workpiece has the electrical characteri-
stics of a coil with a single, short-circui-
ted winding, the high
current generates heat within the
workpiece. Because the heat is
generated within the workpiece, all of
the heater components remain cool.

1.3 Distinguishing feature
The distinguishing feature of the IH 070/090 induction heater is the location
of the workpiece at the same position on the core as the inductive coil. This
design improves efficiency, resulting in less power consumption and faster
heating, which reduces the cost to heat each bearing.
2 Description
The operation of the heater is controlled by the internal electronics in
either of two modes. The operator can either select the desired
temperature of the bearing in TEMP MODE or set the length of time
that the bearing will be heated in TIME MODE. The power level can
be adjusted in steps of 20% for slower heating of sensitive
workpieces (for example, bearings with C1 or C2 clearance).
2.1 Components
The IH 070/090 induction heater contains a U-shaped iron core with an
inductive coil surrounding one of the vertical supports. Internal electronics
control the operation of the heater. A removable yoke on the top of the verti-
cal supports allows the workpiece to be placed onto the heater. The top yoke
of the IH 090 is mounted on a swivel. To accommodate smaller workpieces,
two smaller yokes are also provided. A temperature probe is also included
with the heater. Heat-resistant gloves are also included.

3 Installation of mains plug
Due to the many types of mains plugs, no mains plug is supplied with
the IH 070/090. A qualified electrician must install a suitable mains plug.
The correct supply voltage is shown in section 2.2.
The wires should be connected as follows:
IH 070
Colour of IH 070 wire Mains supply terminal
yellow/green Protection earth (PE)
brown Phase 1 (L1)
blue Neutral (N)
Connect the IH 090 to only two of the three phases. Verify that the
correct circuit breaker is installed. See section 2.2 for circuit breaker
specifications.
