Description

SKF Portable Induction Heater TWIM-15

The SKF portable induction heater TWIM-15 is designed for applications in maintenance jobs to heat up bearings that are mounted with an interference fit onto a shaft. Heating the bearing causes it to expand, which eliminates the need to use force during installation. Generally, using the SKF portable induction heater TWIM-15 to generate a 90 °C (162 °F) temperature difference between the bearing and shaft is sufficient to enable installation. In addition, the TWIM 15 can be used to heat other ring-shaped, metallic components, providing flexibility of use.

The unit has a user-friendly LED control panel that requires no special training and is simple to understand. The panel is used to regulate temperature and also indicates that the TWIM 15 is operational.

Product Features
  • Versatile
    Because of the induction plate’s flat shape, a support yoke is not needed. This increases the type of components that can be heated on the plate and also reduces the number of required accessories.
  • Portable
    Due to the medium-frequency technology used and choice of materials, the heater is lightweight. Also, the built-in handle makes it convenient to transport, and it can be stored easily.
  • Innovative heating
    Utilizing smart construction and operating software, the heater creates a low-temperature difference between the inner and outer ring of the bearing. This reduces the internal tensions generated due to excessive thermal expansion of the inner ring compared to the outer ring
  • Power regulation
    Featuring different power settings, the SKF portable induction heater TWIM-15 can heat-sensitive components at a slower pace. Also, a non-bearing power configuration is possible where most of the power is focused on the bore of the component.
  • Quiet
    Using medium-frequency technology to heat components does not generate noise. A LED indicates when the TWIM 15 is heating, even if you cannot hear it. In parallel, a cooling fan might be heard to help the heater’s electronics to stay cool.

(1) SKF does not recommend heating bearings capped with seals or shields above 80 °C (175 °F). However, if higher temperatures are necessary, please contact us. The heater is designed for maintenance operations where some cooling in between jobs is allowed.

(2) Depending on the geometry of the bearing, maximum heating temperature and power availability.
