Portable induction heater
A light and compact solution for bearing heating
The TMBH 5 (Designation TMBH 5/230V or TMBH 5/120V) portable induction heater is used to heat and mount roller bearings onto a shaft with an interference fit. It is versatile enough to be used in a range of situations – including at a work bench, on the factory floor or out in the field. Typical applications include maintenance and service jobs on assets such as gearboxes, pumps, fans and blowers. The device features near-silent performance and weighs only 3 kg, thanks mainly to the use of sophisticated medium-frequency technology. It features an induction clamp containing internal coils. Current in the coils generates a fluctuating magnetic field. This induces currents in the component, producing heat. Because this heat is generated within the component, not the clamp, the process is very efficient. The heater generates a temperature difference between bearing and shaft. This causes the bearing to expand, so that no force is needed during installation. It can also heat other ring-shaped, metallic components. The unit’s intuitive interface allows the user to select either Temperature Mode or Time Mode. An LED indicator shows when the TMBH 5 is in operation – as it hardly makes any noise.
TMBH 5 Benefits and features:
The TMBH 5 runs in Temperature Mode – where the operator selects the desired bearing temperature – or Time Mode, allowing a bearing or component to be heated for a specified period.
Medium-frequency technology and the use of appropriate materials make the heater lightweight (just 3 kg) and portable. A built-in handle, and storage pockets for ancillary equipment, increase its portability and convenience.
Because of the thin fingers of the induction clamp, the user does not need to choose a different yoke for each component. This means a wider range of different components can be heated – and reduces the number of accessories needed.
TMBH 5 has a variety of power settings, allowing it to heat sensitive components – such as bearings with shields, or metallic inserts in the seals – more slowly if required.
The underlying technology that heats the components operates silently. Because it is so quiet, an LED indicator is needed, to show that the heater is operating.
The TMBH 5 can handle bearings up to 5 kg in weight, with a minimum bore diameter of 20 mm, a maximum of 100 mm and a maximum width of 50 mm. It also incorporates accessories to ensure safe, efficient heating.
These include: a 600 mm temperature probe; a heater clamp; and protective gloves. All items can be stored in an external compartment, further enhancing the unit’s portability and convenience.
