Induction Heater For Bearing Fitting

Induction bearing heaters use magnetic induction to heat but do not magnetize parts.

Induction heater for bearing fitting.

Objective to heat a roller bearing assembly for a shrink fitting application material steel bearings diameters 1 to 3 5 25 4 to 89mm temperature 300ºf 150ºc frequency 180 khz. When choosing a. Skf induction heaters utilise advanced power electronics with application specific designs for high performance. Bearing manufacturers recommend induction heating as the superior heating method.

Toaster oven would be good. Bearing heaters can also be used on gears sprockets pulleys and bushings. As small as that bearing is you need to heat to at least 250 you ll need all the slack you can get to avoid it grabbing halfway on. In addition they are cleaner and require less power consumption thus helping shops to become more energy efficient.

Incorrect methods account for 16 of premature bearing failures. Modern heaters offer many advantages like time or temperature control energy time efficiency safety for part and person. Unlike other bearing heaters there is a clear indication on how long it takes to heat a bearing rather than just the maximum bearing weight possible. Bearing of all types and sizes including the greased and sealed types can be conveniently and safely heated for trouble free mounting.

The reasons why are obvious. As a result by using an skf induction heater the total cost of ownership is often significantly lower. Induction shrink fitting bearings with igbt high frequency heating units. The comprehensive range of skf induction heaters is suitable for most bearing heating applications.

In order to heat a bearing for proper bearing installation you can use multiple methods in this case i will compare using an oil bath heater to using an induction heater. Skf induction heater range. Bearings should never be heated over 120 c 248 f unless specified otherwise. Set temp to 250 wrap bearing in foil stick it in when the oven reaches temp and give it 15 mins or so.

Induction heaters can ensure a safe and thorough heating of the bearing in a controlled environment which helps prevent overheating. In most cases induction heaters are faster than alternative heating options. In an oil bath heater you need a container which will be filled with oil and heated in order to place a bearing in the hot oil to heat the bearing. Heat expands the bearing s inner race for a snug fit without forcing a tight fitting bearing onto a shaft.

Induction heaters are ideally suited for heating bearings and other torque transmitting components like gears and couplings requiring interference fit.
