How to choose Induction heaters

Points to check when selecting, with the values for this product (TIH L44).

  1. 1. Select capacity suited to workpiece mass

    This product: Maximum Workpiece Mass 1200 kg

    The maximum heatable mass varies widely among models, from 40 kg to 1200 kg. Insufficient capacity prolongs heating time and can cause uneven temperature. Select a model with adequate margin over the heaviest bearing or part to be handled, and check the heating performance data in the catalog, such as the mass that can be heated to 110°C within the specified time.

  2. 2. Confirm bore and yoke combination

    This product: Applicable bearing bore diameter range 150–800 mm

    Because the workpiece is heated while threaded over the yoke, the minimum bore that can be handled is determined by the yoke cross-section. Bearings with small bores require thin yokes, so check the number of supplied yokes and the bore range each yoke corresponds to. Dedicated inner ring removal units have a narrow fixed bore range, such as 65 to 130 mm, so match them to the dimensions of the target bearing.

  3. 3. Check that outer diameter and width fit the heating area

    This product: Heating area (width × height) 425 × 492 mm

    If the distance between the support columns or the height is smaller than the workpiece's outer diameter or width, the part cannot be placed. When heating large-diameter or wide bearings, gears or pulleys, also check whether the model has an expanded heating area, or slide-type or swivel-type yokes that make loading and unloading easier.

  4. 4. Verify power capacity and voltage against facility

    This product: Maximum Power Consumption 20 kVA

    Maximum power consumption reaches about 20 kVA on large models, and the unit cannot be used if the facility's incoming power capacity or breaker capacity is insufficient. Supported voltages such as 230 V/400 V also differ by model. Confirm the power specification of the installation site in advance and whether the connection cable length reaches.

  5. 5. Check temperature settings and protection functions

    The maximum heating temperature of the listed products is 250°C. Bearings generally lose hardness and precision when overheated, so check for temperature control using a temperature probe, time setting, and overheat protection. When shrink-fitting parts other than bearings, confirm that the temperature can be set to match the required expansion amount.

  6. 6. Body mass and installation and transport methods

    This product: Body Mass 324 kg

    Body mass ranges from 20 kg to over 400 kg. Small models can be carried and used on site, while large models assume floor mounting or movement by forklift or trolley. Also consider workability, including how the workpiece is lifted, the working space, and whether demagnetization and remote control operation are available.
