SKF Induction Heaters A comprehensive range for bearings and other workpieces

It’s a fact. Incorrect mounting methods account for up to 16% of premature bearing failures To reduce the risk of incorrect mounting, SKF helped pioneer the use of portable induction heaters for bearing mounting applications in the 1970’s. Since that time, there have been many advances in technology and SKF has been at the forefront in developing safer, more efficient and user-friendly bearing induction heaters. SKF Induction Heaters utilise advanced power electronics with application specific designs for high performance. Main causes of premature bearing failures As a result, by using an SKF...

Thermostat controlled bearing heating Electric hot plate 729659 C The SKF 729659 C is a heating device especially designed for pre-heating batches of small bearings prior to mounting. The temperature of the plate can be adjusted to provide temperatures between 50 and 200 °C (120 and 390 °F). The flat heating surface ensures even bearing heating and the cover helps retain heat and keep contaminants out. Technical data Designation Temperature range Plate dimensions (l × w) Heater selection tool The online heater selection tool helps to select the most appropriate SKF heater for a given hot mounting...

A portable solution for bearing heating Portable induction heater TWIM 15 The SKF portable induction heater TWIM 15 is designed for applications in maintenance jobs 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...

Innovative heating 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. 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. Utilizing smart construction and operating software, the heater produces a low temperature difference between the inner and outer ring of the bearing. This reduces the internal tensions generated due...
