Safety recommendations
• Because the TIH L generates a magnetic field, people wearing a pacemaker
must not be within 5 m (16 ft) of the TIH L during operation. Electronic
equipment, such as wristwatches, may also be affected.
• Risk of electrical hazard. Only qualified electrician should open the heater
electrical cabinet.
• Follow the operating instructions at all times.
• Never touch the TIH L coils, core, yoke or workpiece during heating.
• During the heating process observe a safety distance of 1 m (3,3 ft) with the
workpiece, the heater coil or the core.
• Use proper handling equipment when lifting heavy workpieces. Secure the
workpiece with appropriate lifting and handling equipment while heating.
• Make sure the voltage supply is correct.
• Avoid contact with hot workpieces, especially bearing cages, which may be
hotter than the rings. Wear the supplied heat resistant gloves to handle hot
workpieces.
• Never operate the TIH L with the cable of the remote control between the
inductive coils.
• Never operate the TIH L without a yoke in position.
• Electrical arcing may occur when a potential difference exists between the
TIH L and the workpiece. This is not dangerous to human beings and will
not cause damage to the TIH L or the workpiece. However, the TIH L must
never be used in areas where there is a risk of explosion.
• 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.
• Do not modify the TIH L.
• The TIH L must not be exposed to condensing humidity or
direct contact with water.

6SKF TIH L
1. Introduction
The SKF TIH L induction heater is designed to heat bearings, which 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 (162 °F) temperature difference between the
bearing and shaft is generally 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 TIH L has been designed to heat rolling bearings and other metal workpieces that
form a closed circuit. Examples of acceptable workpieces include housings, bushings,
shrink rings, pulleys, and gears. All bearings that fit over the yoke and between the
induction coils can be heated using the TIH L. In addition, other workpiece can also be
placed over the outermost induction coil. See the illustrations at the beginning of this
manual for examples.
1.2 Principle of operation
The principle of operation of the TIH L can
be compared to a transformer.
The high voltage, low electrical current
flowing through a large number of windings in
the TIH L’s induction coils 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.

7SKF TIH L
1.3 Distinguishing features
• High efficiency
With its advanced power electronics and induction coils design, the TIH L has a low
power consumption which represents a high energy savings.
• Versatile heater design: two bearing/workpiece heating positions
TIH L heaters are designed for applications where the bearing is to be heated
vertically to be mounted on an horizontal shaft and applications where the bearing
or workpiece is to be heated horizontally to be mounted on a vertical shaft. See the
illustrations at the beginning of this manual.
The workpiece can therefore be located either over the (sliding) yoke or over the
outermost inductive coil. Bearing should preferably be heated over the (sliding) yoke
while heavy workpiece can be heated over the inductive coil (see chapter 5.8).
• 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 L heater is supplied with a remote control panel
which can be detached from the heater.
• Sliding yoke
To facilitate the handling of the yoke while placing the bearing around it or around
the induction coil, the TIH L is fitted with a sliding arrangement for the yoke. See the
illustrations at the beginning of this manual.
• Bearing supports
To support large workpiece when positioned horizontally around the induction
coil, the TIH L induction heater is provided with two 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 L induction heater contains a U-shaped iron core with two induction coils
surrounding the respectively vertical supports. Bearing supports are delivered to be
mounted on the heater. A detachable remote control panel is included. The remote control
electronics and the internal electronics, control the operation of the heater. A sliding yoke
allows the workpiece to be placed onto the heater. A temperature probe is included with
the heater. Heat-resistant gloves are also included.

13SKF TIH L
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
TIH L 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 reduced internal clearance are heated slowly. Slow heating
ensures that the bearing expands more 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 50% power.
• When using accessory smaller yoke, never exceed 50% power.
Bearings should preferably be heated positioned vertically over the sliding yoke. In the
case of horizontal heating please consider the following:
• For SRB or CARB® bearings, special care must be taken when heating in a horizontal
position and subsequent mounting, especially on vertical shafts. The weight of the
rollers will always set themselves in the lowest position possible: they will be in contact
with both raceways, giving a reduction in the internal clearance. For heavy SRB or
CARB® bearings with heavy rollers we strongly recommend the use of roller centering
ring. The roller centering ring keeps the rollers in position in the middle of the
raceways during the heating process and the mounting.
6. Safety features
The TIH L is equipped with the following safety features:
• Automatic overheating protection.
• Automatic current control.
• Over-current circuit breaker.
• In the TEMP MODE the heater will switch off if the temperature probe does not register
a temperature increase of 1 °C (1.8 °F) every 1 minute (1.00 minute). To increase the
interval to 2 minutes (2.00 minute). press MODE and DOWN at the same time.
• Flashing warning light indicates ongoing heating process.
