Safety Recommendations

The operating instructions must be followed and kept in
a safe place at all times�
The IHN010 device generates a magnetic field� People
wearing a pacemaker, especially if it is an older model, should consult their doctor before operating the device as it could impair the functioning of the pacemaker� Electronic equipment such as wrist watches, memory cards, monitors and displays, magnetic tapes, etc� may also be affected�
Always place the device on a non-metallic surface that is
stable and dry�
Ensure that the ventilation slots are free at all times and
the device can draw in cold air through its base�
The device must always be connected to an AC power
network with the correct voltage as indicated on the type plate�
Ensure that the device does not get wet and do not
expose it to high humidity levels�
The device must not be immersed in water or any other
liquid�
Do not operate the device in the vicinity of heat sources
and ensure that it is placed a sufficient distance away from walls and flammable objects�
The device must not be used in areas where there is a
risk of explosion�
Do not activate the heating process if no rolling bearing
or other workpiece is in place�
Avoid contact with hot workpieces� Wear the supplied
protective gloves when handling hot workpieces�
Please ensure that you always use a power and
temperature level that is appropriate for the workpiece in question to ensure that it is heated carefully and not damaged�
The device is intended for heating rolling bearings� The
manufacturer accepts no liability in the event of inappropriate or incorrect usage�
Regularly check the plug, connecting cable and heating
cone for wear and tear or damage� If you discover any damage, send the device to your NSK partner for inspection�
Do not modify the device�
1 Introduction
The IHN010 induction heater is designed for heating rolling bearings and other ferritic, circular workpieces� The heat causes the workpiece to expand, which eliminates the need to use force during installation� A 90°C (194°F) temperature difference between the bearing and shaft is sufficient to enable easy 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 IHN010 portable induction heater has been designed to heat rolling bearings� Examples of acceptable workpieces include bushings, shrink rings, pulleys, rings, etc� The IHN010 portable induction heater is primarily intended for on-site repairs and rolling bearing replacements by service and maintenance staff�

1.2 Principle of Operation
The IHN010 generates a magnetic field in the medium frequency range (approx� 25kHz), similar to an inductive hot plate� The magnetic field induces a voltage targeted on the inner ring of the workpiece� This creates eddy currents, which efficiently heat the workpiece� As the heat in the workpiece is generated by the current flow, all other parts of the induction heater remain cold� The heating process is based on the prin­ciple of eddy currents, so the workpieces to be heated should be composed of ferritic (magnetic) metals� In case of doubt, simply check the workpiece using the magnet of the tempera­ture probe� This patented heating method enables fast, easy and energy efficient heating of workpieces�
1.3 Distinguishing Feature
The distinguishing feature of the IHN010 induction heater is the fact that the workpiece can only be placed on the cone-shaped workpiece support for heating� The energy transfer is contact-free, and is generated via the medium-frequency coil situated be­low� The cone-shaped workpiece support creates an optimal magnetic field distribution in the rings of the rolling bearing, thereby ensuring that heat is distributed homogenously� This design improves efficiency, resulting in lower power consumption and faster heating, which significantly reduces the costs of heating the bearings� This special technology allows the device to be very light weight and portable� In addition, the device is fitted with predictive temperature control (PTC)� For every heating process, the temperature increase curve of the workpiece/rolling bearing is measured constantly, thereby opti mising the heating perfor­mance� This ensures that the target temperature is achieved quickly without overheating the rolling bearing�
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 in steps of 20% for slower heating of sensitive workpieces (for example, bearings with C1 or C2 clearance)�
2.1 Components
The IHN010 induction heater is comprised of a portable housing with integrated operating electronics and cone-shaped workpiece support� A temperature probe can be attached for measuring and monitoring the temperature of the workpiece� The mains cable is enclosed separately, as are protective gloves for safe handling of hot workpieces� All of the equipment can be stored in the practical carrying case�
