Positioning the CARB® bearing system onto the custom-designed induction heater.

Giant Scale Innovation

Induction heater for bearing assembly.

So when the time came for the bearings and their two 8,000-kg housings to be heated for correct assembly and installation, SKF designed and had built a 1,000-kVA (kilo volts x amps = kiloWatts) induction heater.

Also, because the weight of the roller set in the CARB® bearing is almost 800 kg, it had to be specially clamped during heat-up and assembly. Without induced safe-clamping, the weight of the roller set would make the rollers clamp loosely between the inner and outer ring, which could damage the raceways.
