Storage of the small and medium yokes is in the yoke storage at the heater circuit breaker side. Two yoke storage are located behind the folding bearing supports. Yoke storage All three yokes can be stored inside the heater. See the illustrations at the beginning of this manual. Folding bearing supports To support large bearing positioned around the inductive coil the TIH 030m induction heater is fitted with folding bearing supports. This design improves efficiency, resulting in less power consumption and faster heating, which reduce the cost to heat each bearing. Inductive coil When heated the workpiece is located at the same position on the core as the inductive coil. 6 SKF TIH 030mħ 1.3 Distinguishing features Remote control panel To improve the ease of use and to diminish the risk of contact with the hot bearing during operation, the TIH 030m heater is supplied with a remote control panel which can be detached from the heater. Because the heat is generated within the workpiece, all of the heater components remain cool. Because the workpiece has the electrical characteristics of a coil with a single, short-circuited winding, the high current generates heat within the workpiece.
The high voltage, low current electricity flowing through the large number of windings in the inductive coil induces low voltage, high current electricity in the workpiece. 1.2 Principle of operation The TIH 030m generates heat by means of a large electrical current that is magnetically induced in the workpiece by a coil within the heater.

See the illustrations at the beginning of this manual for examples. In addition, smaller bearings can be placed over any of the three standard yokes. All bearings that fit over the inductive coil and between the vertical supports with the top yoke in place can be heated using the TIH 030m. Examples of acceptable workpieces include bushings, shrink rings, pulleys, and gears. However, other metal workpieces that form a closed circuit can also be heated. 1.1 Intended use The TIH 030m has been designed to heat rolling bearings. At an ambient temperature of 20 C (68 F), the bearing must therefore be heated to 110 C (230 F). A 90 C (162 F) temperature difference between the bearing and shaft is generally sufficient to enable installation. The heat causes the bearing to expand, which eliminates the need to use force during installation. INTRODUCTION The SKF TIH 030m induction heater is designed to heat bearings that are mounted with an interference fit onto a shaft. Wear the supplied heat resistant gloves to handle hot workpieces. Use proper handling equipment when lifting heavy workpieces. Never operate the TIH 030m with the cable of the remote control between the vertical supports of the yoke. Never operate the TIH 030m without a yoke in position. Do not expose the TIH 030m to high humidity.
However, the TIH 030m must never be used in areas where there is a risk of explosion. This is not dangerous to human beings and will not cause damage to the TIH 030m or the workpiece. Electrical arcing may occur when a potential difference exists between the TIH 030m and the workpiece. Be certain that the voltage supply is correct. Follow the operating instructions at all times.
Electronic equipment, such as wristwatches, may also be affected. 3 Table of contents EU-DECLARATION OF CONFORMITY.4 SAFETY RECOMMENDATIONS INTRODUCTION Intended use Principle of operation Distinguishing features DESCRIPTION Components Technical data INSTALLATION OF MAINS PLUG PREPARATION FOR USE OPERATION Function of displays Function of buttons TEMP MODE TIME MODE Temperature measurement Change of temperature unit Demagnetisation Power level selection SAFETY FEATURES TROUBLESHOOTING SPARE PARTS.15 SKF TIH 030m 3Ĥ EU-DECLARATION OF CONFORMITY We, SKF Maintenance Products, KelvinbMT Nieuwegein, declare that the INDUCTION HEATER TIH 030m is designed and manufactured in accordance with the EUROPEAN LOW VOLTAGE DIRECTIVE 73/23/EEC EMC NORM 89/336/EEC, outlined in harmonised Norms VDE 0721 EN EN EN /3.2 The Netherlands, 20 August 2004 Ebbe Malmstedt Manager Product Development and Quality 4 SKF TIH 030mĥ SAFETY RECOMMENDATIONS Because the TIH 030m generates a magnetic field, people wearing a pacemaker must not be within 5 m (16 ft) of the TIH 030m during operation.
