Safety recommendations
• Because the TIH 220m generates a magnetic eld, people wearing a
pacemaker must not be within 5 m (16 ft) of the TIH 220m during
operation. Electronic equipment, such as wristwatches, may also be
affected.
• During the heating process observe a safety distance of 50 cm (1.6 ft)
with the workpiece, the heater coil or the core.
• Follow the operating instructions at all times.
• Make sure the voltage supply is correct.
• Electrical arcing may occur when a potential difference exists between
the TIH 220m and the workpiece. This is not dangerous to human beings
and will not cause damage to the TIH 220m or the workpiece. However,
the TIH 220m must never be used in areas where there is a risk of
explosion.
• The TIH 220m must not be exposed to condensing humidity or direct
contact with water.
• Never touch the TIH 220m coil, core, yoke or workpiece during heating.
• Never operate the TIH 220m without a yoke in position.
• Never operate the TIH 220m with the cable of the remote control
between the vertical supports of the yoke.
• Do not modify the TIH 220m.
• Use proper handling equipment when lifting heavy workpieces.
• Avoid contact with hot workpieces, especially bearing cages, which are
hotter than the rings. Wear the supplied heat resistant gloves to handle
hot workpieces.
• When using induction heating, the temperature generated in the bearing
inner ring will be higher than the temperature in the bearing
outer ring. Ensure that the different expansion of the rings does not
block the rolling elements.
• Ensure the yoke is applied with the ground faces pointing downward, and
in proper contact with the core uprights.

1. Introduction
The SKF TIH 220m induction heater is designed to heat bearings, which are mounted with
an interference t onto a shaft. The heat causes the bearing to expand, which eliminates
the need to use force during installation. A 90 °C (162 °F) temperature difference
between the bearing and shaft is generally sufcient 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 TIH 220m 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 t over the
induction coil and between the vertical supports with the top yoke in place can be heated
using the TIH 220m. In addition, smaller bearings can be placed over any of the two
standard yokes. See the illustrations at the beginning of this manual for examples.
1.2 Principle of operation
The principle of operation of the TIH 220m can be compared to a transformer. The
high voltage, low electrical current owing through a large number of windings in the
TIH 220m’s induction 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 features
• Remote control panel
To improve the ease of use and to help reduce the risk of contact with the hot bearing
during operation, the TIH 220m heater is supplied with a remote control panel which
can be detached from the heater.
• Inductive coil
When heated the workpiece is located at the same position on the core as the inductive
coil. This design improves efciency, resulting in less power consumption and faster
heating which reduces the cost to heat each bearing.
• Folding bearing supports
To support large bearings positioned around the induction coil, the TIH 220m induction
heater is tted with folding bearing supports. See the illustrations at the beginning of
this manual.
• Sliding yoke
To facilitate the handling of the yoke while placing the bearing around the induction coil
or around the top yoke, the TIH 220m is tted with a sliding arrangement for the large
yoke.
• Yoke storage
The small yoke can be stored inside the heater. The yoke storage is located behind the
folding bearing supports. See the illustrations at the beginning of this manual.
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 to 100% or 50% for slower heating of sensitive workpieces (for
example, bearings with C1 or C2 clearance).
2.1 Components
The TIH 220m induction heater contains a U-shaped iron core with an induction coil
surrounding one of the vertical supports. A detachable remote control panel is included.
The remote control electronics and the internal electronics, control the operation of the
heater. A removable yoke on the top of the vertical supports, allows the workpiece to
be placed onto the heater. The largest of the two yokes can slide on its vertical post. To
accommodate smaller workpieces, a small yoke is also provided.
A temperature probe is included with the heater. Heat-resistant gloves are also included.
