Safety recommendations
• Because the IH 210 generates a magnetic field, people wearing a
pacemaker must not be within five meters of the IH 210 during ope-
ration. Electronic equipment, such as wristwatches, may also be affec-
ted.
• 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 210 and the workpiece. This is not dangerous to human
beings and will not cause damage to the IH 210 or the workpiece.
However, the IH 210 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 210 without a yoke in position.
• Do not modify the IH 210.
• Use proper handling equipment when lifting heavyworkpieces.
• Avoid contact with hot workpieces. Wear the supplied heatresistant
gloves to handle hot workpieces.

1 Introduction
The simatec IH 210 induction heater is designed to heat bearings that are
mounted with an interference fit onto a shaft. The heat causes the bearing
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 210 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 sliding yoke in place can be heated using the IH 210.
In addition, smaller bearings can be placed over either of the two standard
yokes. See the illustrations at the beginning of this manual for examples.
1.2 Principle of operation
The IH 210 generates heat by
means 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
characteristics of a coil with a
single, short-circuited 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 210 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 210 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 sliding yoke on the top of the
vertical supports allows the workpiece to be placed onto the heater.
To accommodate smaller workpieces, a small yoke is 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 210. 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:

4 Preparation for use
• Place the IH 210 in the horizontal position on a stable surface.
• Connect the mains plug to a suitable mains supply.
• For workpieces with an internal diameter (>135mm) 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.
- If the sliding yoke is not installed on the IH 210, follow the
steps shown in the illustrations at the beginning of this manual.
Remove the protective film from the bright underside of the
sliding yoke before the first use.
- Slide the sliding yoke to the right 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 two yokes that fit through the internal
diameter of the workpiece.
- If necessary, remove the sliding yoke from the IH 210.
- Verify that the protective film has been removed from the
underside of the small 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 210 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.
• Switch the IH 210 on using the power switch on the left side.
• Observe the self-test of the display and signal tone.
