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 an 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.
• 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.

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 can be heated to a maximum temperature of 240ºC (464°F), except
for the EBH 2412 type where the maximum temperature is set at 150ºC (300°F).
Bessey induction heaters are suitable for continuous use. However, when heating to 240°C
(464°F), don’t do so for more than half an hour. The EBH 2412 has a duty cycle of 1,5 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.
• We recommend to use an external thermometer to monitor the workpiece temperature.
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.
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.

4. Installation
• Remove the packaging and place the induction heater on a non-ferrous, stable and level
surface.
• Check the connection voltage against the rating plate on the unit.
• Each heater is equipped with a plug. C-US plug types are:
120V/240V 1 phase heaters
Black Phase
White Zero
Green Ground
• Ensure that the power supply cable cannot come into contact with the workpiece to be
heated. Insert the plug in a grounded socket outlet with connection.
• As there is a wide variety of plug types, the provided plug may not t. In such cases, obtain
a proper plug. It must be tted by a qualied electrician. There are dierent tting options
depending on the type of cable on the heater:

5. Method of operation
WARNING!
• Use suitable lifting equipment for heavy crossbars and workpieces. Prevent
personal injury by improper handling.
• The weight of the workpiece may not exceed the value given in section 5.3
and in the technical specications. This can cause failure of the device and
personal injury.
• Ensure that the power supply cable cannot come into contact with the
workpiece to be heated. Damage to the cable can cause electrocution!
• 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.
A workpiece can be placed in dierent ways:
Hanging, with crossbar through
the workpiece
Horizontal, with workpiece
around the pole
Large workpieces can be thermally insulated by wrapping them in insulating material, such as
a welding blanket. This ensures that the heat stays in the workpiece and does not dissipate.

14 © Bessey Tools
5.1 Heating a hanging workpiece
• Place the induction crossbar with the bearing on the poles. Make sure that the bare metal
side is positioned straight on the poles.
• Always choose an induction crossbar that lls the bore of the bearing as much as possible.
You can even use 2 crossbars at the same time. This promotes optimal, fast and even heating.
• Make sure that the bare-metal sides are suciently coated with acid-free grease to ensure
optimal contact and avoid vibration.
• Always make sure that the workpiece does not come into contact with the plastic casing
of the heater. When the heating is nished, follow the instructions in reverse order. Use
heat-resisant gloves to move the heated workpiece.
5.2 Heating a horizontal workpiece
• This is only possible if the bore of the workpiece is large enough to t over the pole.
• Place the workpiece as centrally as possible around the pole on the horizontal supports.
• The workpiece may not be wider than the horizontal supports.
• Always choose the largest induction crossbar.
• Make sure that the bare-metal sides are suciently coated with acid-free grease to ensure
optimal contact and avoid vibration.
• Always make sure that the workpiece does not come into contact with the plastic casing of
the heater.
• When the heating is nished, follow the instructions in reverse order. Use heat-resistant
gloves to move the heated workpiece.
