The new FAG HEATER generation heats workpieces of up to 1.6 tons with efficiency values of up to 0.9.
The Delta-T control regulates the temperature difference between the inner and outer side of the component being heated and thus ensures a safe and even heating process.
A touchscreen with a user-friendly menu and clear text messages make the new heating devices intuitive to operate.

Besides their high performance, the new generation of FAG HEATER devices are characterized by their safe heating operation and intuitive touchscreens. The broad range of HEATER devices also mean that rolling bearings weighing up to 1.6 tons can be heated faster and more economically.
With its latest generation of FAG HEATER heating devices, Schaeffler is setting new standards in the mounting of rolling bearings. These new HEATER devices are equipped with a Delta-T control as standard, which uses two sensors to continuously measure the temperature difference between the inner and outer side of the component being heated during the heating process. Damage caused by preloading in the workpiece is prevented, as the device’s output is reduced shortly before a preset maximum temperature difference is reached, which gives the heavier outer ring enough time to expand to the required extent. This makes the Delta-T control a particularly safe solution for rolling bearings. The heating process can also be started with a time delay via remote control in order to provide increased safety for the mounting personnel.
Easy to operate
The user-friendly menu is available in over 20 languages. Using the intuitive touchscreen, the user can select from four different heating methods. The system additionally allows the heating process to be documented, favorites lists to be created, and heating curves to be graphically illustrated.
Faster heating saves energy
Thanks to the optimizations made to the devices’ performance capability, their efficiency has now been increased from 0.23 to values of up to 0.9. This reduces the heating time and energy consumption, which in turn means lower operating costs. The even and controlled heating process is made 30 to 50 percent faster by a microprocessor-controlled system of electronics.
The new FAG HEATER devices are used in the wind power, steel, and paper industries as well as numerous other sectors. A broad range of bearing sizes – from bores of 15 millimeters through to outside diameters of up to two meters – can be heated using this range of devices, which includes both table units and floor units. Besides conventional rolling bearings, these devices can also be used to heat clutches, gears, and other ferromagnetic components quickly and safely.
