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.

• For the IH 090 only, follow these steps to install the swivel arm:
- Attach the protection plate (4) to the side post to prevent damage.
- Install the swivel head (1) and the swivel body (2) on the lefthand
side post of the heater.
- Install the large top yoke (55 x 55mm) in the swivel head.
Adjust the swivel body so that there is no visible gap (A)
between the side post and the yoke.
- Tighten the four screws (3) of the swivel body (maximum
torque 5Nm).
- Turn the screw (5) on top of the swivel head to position the top
yoke. The top yoke must contact as much of the upper surface
of the right-hand side post (B) as possible. Noise during
operation could indicate that the top yoke is not positioned
properly.
• Special notes for the IH 090:
- The yoke support is required when either of the smaller yokes
(28 x 28mm or 14 x 14mm) is installed. Install the yoke
support and the yoke together in the swivel head. If necessary,
rotate the swivel head to provide better access.
4 Preparation for use
• Place the IH 070/090 in the horizontal position on a
stable surface.
• Connect the mains plug to a suitable mains supply.

- Heavy workpieces (≥10 kg/22 lbs) that must be installed on
the top yoke should be supported until the yoke is in the correct
position on the right-hand side post. The heater may tip over if
the workpiece is not supported.
- The swivel body (2) can remain on the heater at all times.
• For workpieces with an internal diameter large enough to fit over
the inductive coil, follow these steps:
- Place the workpiece over the inductive coil using appropriate
lifting equipment.
- For best performance, adjust the position of the workpiece so
that the inductive coil is in the centre.
- Remove the protective film from the bright underside of the top
yoke before the first use.
- Position the top yoke so that it completely covers the top of
both vertical supports.
• For workpieces that do not fit over the inductive coil, follow these
steps:
- Choose the larger of the three yokes that fit through the internal
diameter of the workpiece.
- If necessary, remove the top yoke from the IH 070/090.
- Verify that the protective film has been removed from the
underside of the small or medium yoke if it is to be used for the
first time.
- Slide the workpiece onto the yoke that you have selected.
- Position the yoke on the IH 070/090 with the bright
underside resting evenly on the two vertical supports.
• If you will use TEMP MODE, plug the temperature probe into the
connector on the left side of the heater. Place the magnetic end of
the probe on the inner ring of the bearing or on the innermost
surface of the workpiece.
• Use the power switch on the left side to switch on the IH 070/090.
• Observe the self-test of the display and signal tone.

5.3 Temp mode
• If the main display shows ‚t‘, press MODE to select TEMP MODE.
The main display shows °C or °F in TEMP MODE.
• The selected temperature is shown on the main display. The
default temperature for bearings is 110°C (230°F). If a different
temperature is desired, press UP or DOWN to adjust the
temperature in steps of 1°.
• It may be desirable to heat bearings to temperatures above 110°C
(230°F) for increased mounting time. Consult the bearing
specifications to determine the maximum permitted temperature.
Always ensure the bearing does not lock due to an excessive
expansion of the inner ring compared to outer ring. See section 5.8.
• All Spherical Roller Bearings (SRBs) are subjected to a
special heat treatment. These bearings can be operated at
temperatures as high as 200°C (392°F). Heating these bearings
above 110°C (230°F) will not cause any damage as long as the
bearing is still able to rotate. For other bearings, a temperature of
125°C (257°F) must not be exceeded unless otherwise specified.
• Press POWER to select the power level. Use the guidelines in
section 5.8 to determine the correct power setting.
• Make sure the temperature probe is mounted on the bearing inner
ring.
• Press START/STOP to start the heater. The main display shows
the current temperature of the workpiece.
• When the selected temperature has been reached, the heater
demagnetises the workpiece, switches off, and generates an
acoustic signal for 10 seconds or until START/STOP is pressed.
• Press START/STOP to stop the heater.
• Remove the workpiece with proper handling equipment.
• If the workpiece remains on the heater, the heater will start again
when the temperature of the workpiece drops 10°C (18°F). Press
START/STOP to stop the heater and demagnetise the workpiece.
• The IH 070/090 is now ready to heat another workpiece
with the same settings.

section 5.8 to determine the correct power setting.
• Press START/STOP to start the heater. The main display shows
the time that remains.
• When the time has elapsed, the heater demagnetises the
workpiece, switches off, and generates an acoustic signal for
10 seconds.
• Press START/STOP to cancel the acoustic signal and stop the
heater.
• Remove the workpiece with proper handling equipment.
• The IH 070/090 is now ready to heat another workpiece
with the same settings.
5.5 Temperature measurement
When the heater is not operating, the temperature of the workpiece can be
measured by pressing MODE and START/STOP at the same time. The LED
on the START/STOP button flashes during temperature measurement. Press
START/STOP to cancel temperature measurement.
5.6 Change of temperature unit
Press MODE and UP at the same time to switch between °C and °F. The tem-
perature unit setting remains the same even after disconnection from mains
power.
5.7 Demagnetisation
The workpiece is automatically demagnetised when heating is complete.
Demagnetisation will not occur if the power is interrupted or the main switch
is switched off. To use the IH 070/090 for demagnetisation only, select TIME
MODE and set the time to 0.1 minute (6 seconds).

5.8 Power level selection
When heating bearings with an induction heater, most of the heat will
be generated in the inner bearing race. The heat will then be transferred
through the bearing. It is therefore important that bearings with small inter-
nal clearance or slight preload are heated slowly. Slow heating ensures that
the bearing expands evenly, thereby preventing damage to the bearing.
The shape, weight, size, and internal clearances all affect the amount
of time required to heat a bearing. The large variety of bearing types
precludes the possibility of providing a specific power level setting for
each type. Instead, the following guidelines are provided:
• For sensitive bearings (including bearings with C1 or C2 internal
clearance) or bearings with brass cages, do not exceed 20%
power when using the small yoke, 40% power when using the
medium yoke, or 60% power when using the large yoke.
• When using the small yoke, never exceed 40% power.
• When using the medium yoke, never exceed 60% power.
6 Safety features
The IH 070/090 is equipped with the following safety features:
• Automatic overheating protection
• Automatic current control
• In the TEMP MODE the heater will switch off if the temperature
probe does not register a temperature increase of 1° every
15 seconds. To increase the interval to 30 seconds, press MODE
and DOWN at the same time.
• Additionally, the IH 090 is equipped with a main switch with
over-current circuit breaker.
