Safety recommendations
• Because the TIH L MB generates a magnetic field, people wearing a
pacemaker must not be within 5 m (16 ft) of the TIH L MB 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 MB coil, 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. Wear the supplied heat resistant gloves to
handle hot workpieces.
• Never operate the TIH L MB with the cable of the remote control between
the heater core.
• Never operate the TIH L MB without a yoke in position.
• Electrical arcing may occur when a potential difference exists between the
TIH L MB and the workpiece. This is not dangerous to human beings and will
not cause damage to the TIH L MB or the workpiece. However, the
TIH L MB must never be used in areas where there is a risk of explosion.
• 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 MB.
• The TIH L MB must not be exposed to condensing humidity or direct contact
with water.

1. Introduction
The SKF TIH L MB induction heaters are designed to heat work pieces others than bearings
such as gears, couplings, bushings, pulleys, etc. The heat causes the workpiece to expand,
which eliminates the need to use force during installation. A 90 °C (162 °F) temperature
difference between the workpiece and shaft is generally sufficient to enable installation. At
an ambient temperature of 20 °C (68 °F), the workpiece must therefore be heated to 110
°C (230 °F).
1.1 Intended use
The TIH L MB has been designed to heat metal workpieces that form a closed circuit.
Examples of acceptable workpieces include housings, bushings, shrink rings, pulleys, and
gears. All workpieces that fit over the yoke and between the induction coils can be heated
using the TIH L MB. 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 MB can be compared to a transformer.
The high voltage, low electrical current flowing through a large number of windings in the
TIH L MB’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 MB
1.3 Distinguishing features
• Inductive coil
When heated the workpiece is located at the same position on the core as the
inductive coil. This design improves efficiency, resulting less power consumpton
and faster heating which reduces the costs to heat each workpiece.
• High efficiency
With its advance power electronics and induction coils design, the TIH L MB has a low
power consumption which represents a high energy savings.
• Remote control panel
To improve the ease of use and to help reduce the risk of contact with the hot
workpiece during operation, the TIH L MB 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 workpiece around it or around
the induction coil, the TIH L MB is fitted with a sliding arrangement for the yoke. See
the illustrations at the beginning of this manual.
• Folding workpiece supports
To support large workpiece when positioned horizontally around the induction coil,
the TIH L MB induction heater is provided with two 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 workpiece in
TEMP MODE or set the length of time that the workpiece will be heated in TIME MODE.
The power level can be adjusted to 100% or 50% for slower heating of sensitive workpieces
(for example, materials like aluminum or brass).
2.1 Components
The TIH L MB induction heater contains a U-shaped iron core with one induction coil.
Workpiece 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 MB
5.8 Power level selection
When heating workpieces with an induction heater, the most of the heat will be generated
in the bore and then transferred through the workpiece. Slow heating ensures that
the workpiece expands more evenly, thereby preventing damage. The large variety of
workpieces precudes the possibility of providing a specific power level setting for each type.
Instead, the following guidelines are provided:
• For sensitive workpieces, with a combination of different materials (such as
aluminum, brass), do not exceed 50% power.
• When using accessory smaller yoke, never exceed 50% power.
6. Safety features
The TIH L MB 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).

9. Maintenance
The correct maintenance of the heater is important to achieve the full service life of the
product, ensure the best performance and avoid related risks.
The following advises should be taken into consideration before using the product:
• Check that there are no damages in the housing.
• Check that there are no damages in the insulation of the cable and in the plug.
If so, replace them.
• Check that the lamination of the yoke is not broken. If the delamination get’s too much,
then replace the yoke with a new one to avoid extreme noise and efficiency losses.
• Check that the yoke is in good contact with the U-shaped core. The contact area should
be clean and rust-free. There should not be air gaps between the surfaces. Non-parallel
surfaces might generate vibrations and loud noises and cause efficiency losses.
• Check that the closing system (if any, sliding rails or swiveling hinge) is not damaged.
• Check that the temperature probe, cable and plug are clean and not broken. Otherwise
the temperature reading and control might not work properly.
When required and at regular intervals:
• Clean the heater using only a clean dry cloth.
• Clean the contact surfaces in between the yoke and the U-shape core. Add a layer
of LGAF 3E anti-fretting paste to protect the surface area. This will help to keep the
surfaces rust-free, reduce the heater noise and maintain heater efficiency.
• Adjust the closing swivel system if required by using the screws in the hinge.
