The SKF portable induction heater TWIM 15 is designed to heat up roller 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 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.
Utilizing electrical power, the TWIM 15 features glass-fiber, high-temperature-resistant plastic construction that allows a low temperature difference between the inner and outer rings of the bearing. This helps to reduce internal tensions that are generated due to excessive thermal expansion of the inner ring compared to the outer ring.
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.
TWIM 15 advantages:
The TWIM 15 portable induction heater package includes:
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 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.

ACCESSORIES:
Carry your TWIM 15 induction heater in a convenient way
The SKF TWIM 15-BAG is optional to the TWIM 15. The bag provides extra portability to the SKF TWIM 15 induction heater. It has two pockets to provide space for your heat resistant gloves, the temperature probe and the instructions for use – having the heater and all its accessories together. Like the induction heater, the TWIM 15-BAG has a compact design.
The bag helps you to maintain your heater clean and protected. For example, the bag provides shelter to the heater keeping it free from dust and industrial pollution while stored. The sturdy material of which the bag is made of protects it against scratches from other tools and mishandling. Easy and safe to carry it in the trunk of a car.
It also features a shoulder strap which facilitates bringing the heater into the field. You can carry it now hands free!
