Foreword
The Bessey induction heating devices give rapid, clean operation. Their high eciency level
allows energy-ecient heating and shorter mounting times. This reduces the operating costs.
The uniform, controlled heating allows consistently good quality of mounting.
Operation is simple and user-friendly, the touch-sensitive screen is oil-resistant, dustproof
and waterproof.
When heating by induction is used, there is no need at all to use oil – this gives particularly
good environmental compatibility. The scope of application is very extensive. It is possible
to heat the loose inner rings of cylindrical or needle roller bearings as well as sealed and
greased bearings.
In order to ensure durability in demanding industrial operation, the devices are extremely
robust and reliable.

2�2 Description of potential hazards
Warning! Voltage
Be aware that you are working with an electrical device. On the mains side as
well as internally, voltages occur that can lead to serious injury and death if
used inexpertly or improperly.
• Connect the unit to the power according to the information on the rating plate.
• Before each use, check the power supply cable for damage.
• Safe disconnection from the power supply must be ensured at all times
before starting maintenance and repair work. This can be achieved by
removing the power plug from the socket.
Warning! Electromagnetic eld
Be aware that you are working with a device that generates electro-magnetic
elds. Keep a distance of 1 metre from the unit after switching on.
These elds can be harmful for persons with active medical aids such as
pacemakers.
These elds can be harmful for persons with passive medical aids such as joint
prostheses. The wearing of jewellery can also result in injuries due to burns.
It is forbidden for persons with active medical aids to be in the immediate
vicinity of the unit when it is in operation. The generated electromagnetic eld
may inuence the proper function of such medical aids.
It is forbidden to wear jewellery when working with the generator and
inductors. There is a risk of the jewellery being heated by the electromagnetic
eld and resulting in injuries due to burns.
For this reason, persons with passive implants are recommended not to enter
the immediate vicinity of the induction heater when it is in operation.
Furthermore, it cannot be ruled out that the electromagnetic elds could
cause damage to electronic and magnetic data media. Keep such equipment
away from the induction heater.

Caution! Tripping hazard
Limit the risk of injury due to tripping as far as possible.
• Keep your place of work tidy. Remove any loose and superuous objects
from the immediate vicinity of the unit.
• Position any cables, including the power supply ones, as low as possible to
minimize the risk of tripping.
Caution! Risk of burns
The workpiece becomes warm to very hot during heating.
Parts of the unit may also become hot due to contact with the workpiece or
the heat radiated by the workpiece.
Therefore always wear heat-resistant gloves when handling workpieces in
order to avoid injury due to burns.
Caution! Risk of injury during lifting
A number of units in the Bessey heater range weigh more than 23 kg and may
therefore not be lifted by one person alone. (see technical specs)
If a unit weighs more than 23 kg, lift it with two persons or use suitable
lifting equipment.
Wear safety shoes to prevent injury from unintentionally falling workpieces
and/or machine parts.

2�3 Safety measures to be taken
• The user must carefully read this manual and be familiar with the safety standards in the
work practice.
• Follow the instructions in the manual at all times.
• Check the connection voltage against the rating plate on the unit. If the power cord does
not have one, make sure it is tted with the proper plug. This must be tted by a
qualied electrician.
• Never use or store an induction heater in a damp environment.
• Only use Bessey induction heaters indoors.
• If using a mobile version; always lock the castors when not moving the device.
• If the heater is equipped with extendable horizontal supports, always secure them with
the appropriate locking pin, both in the fully retracted and in the fully extended position.
• Use suitable lifting equipment according to the weight of the crossbar or component.
• Never use a metal strap to support workpieces or suspend them in the magnetic eld.
High currents could start running through the strap, causing it to heat up.
• Do not hold metal objects near crossbar and poles.
• Whilst heating, observe a minimum distance of 1 metre from the heater.
• Never remove the induction crossbar during heating.
• Do not modify the heater. Never use home-made crossbars.
• Always check that the induction crossbar is positioned correctly against the poles, so
excessive vibration cannot cause personal injury or damage to the device.
• Do not switch on the heater until the core is closed with a crossbar.
• In the event that smoke or vapor is emitted from the workpiece during heating, ensure that
there is extraction or sucient ventilation in the workshop. Do not inhale vapours or fumes!
Hazard area
The hazard area of the heating device can represent a danger of death.
DANGER!
Danger of heart stoppage in persons tted with a pacemaker due to the strong
electromagnetic eld. Ensure that persons tted with a pacemaker remain
outside the hazard area of the heating device. Erect barriers and attach clearly
visible warning signs, Figure 1.
WARNING!
Danger of death for persons with articial heart valves made from metal,

2�4 Safety provisions
• The electronic systems switch o automatically if the ambient temperature rises
above 70ºC.
• When heating in temperature mode, the heater switches o if no 1°C temperature
increase is measured during a time pre-set by the manufacturer.
• The coil of the heater is equipped with a temperature monitor. If the coil becomes too hot,
the heating process is switched o entirely.
• Models with a swivel arm are equipped with a safety positioning cam.
An induction heater operates by means of a magnetic eld. At a distance of 1 metre, the
magnetic eld has been reduced to such an extent that it is below the applicable standard
of 0.5mT.

3. Introduction
3�1 Application
Bessey induction heaters are intended for heating bearings, so they can be assembled easily
by means of a shrink t. Subject to professional assessment, they can also be used to heat
bushings, cogwheels, couplings and metal objects that form a closed circuit. Bearings and
workpieces are demagnetised automatically after each heating cycle.
Bearings and workpieces can be heated to a maximum temperature of 240ºC (464°F).
Bessey induction heaters are suitable for continuous use. However, when heating to 240°C
(464°F), do not do so for more than half an hour.
CAREFUL!
• Bearings may be heated to a maximum of 120°C (248°F).
• Precision bearings may be heated to a maximum of 70°C (158°F). Higher temperatures
can aect metallurgical structure and lubrication, resulting in instability and failure.
• Do not use a heater for bearings and workpieces that are outside the minimum and
maximum dimensions specied in the technical specications.
• Never switch o the unit with the main switch while it is still heating up.
3�2 Operating conditions
• Only use the device indoors.
• Fit for use in an industrial environment, at an ambient temperature of 0ºC (32°F) to 50ºC
(120°F) and humidity of 5 to 90% – non-condensing.
At temperatures below 0°C (32°F), the unit stops operating.
3�3 Principle of operation
The operation of the heater is based on inducing a (low frequency)
current in the bearing. This is achieved by incorporating the bearing
as a secondary winding in a transformer.
The primary winding is connected to the mains by means of an
electronic controller. The magnetic eld induces a high current
(short-circuit current) through the bearing, which then becomes hot.
After each heating cycle, the bearing or workpiece is demagnetised.
