Bearing temperature of reasons:

The first: oil quality is worse? If oil viscosity can also lead to INA bearing temperature;

The second: bearing institutions assembly if too close, insufficient clearance can also lead to flange bearing temperature;
Third: bearing assembly close can also lead to bearing temperature;
Fourth: the circle in the bearing shaft or shell and turn can also lead to bearing temperature;

Fifth: bearing load bearing can also lead to excessive temperature;
Sixth: if bearing maintains a or rolling body chipped word, also can lead to bearing temperature.

Bearing pressure into the INA after bearing should be flexible rotation without block feeling. If there are obviously not flexible rotation, indicates that the size of the shaft is too big, tolerance to cut. Such as import bearing pressure into the shaft with hand after turning have obvious "sasha vujacic" feeling, likely is the tolerance of shaft is too large or shaft roundness is bad. So in control the axis and bearing room also want to control the tolerance roundness, the home a lot of manufacturers to only tolerance control, no control to roundness.

Because the flange bearing is high precision products, such as assembly not easily on the channel bearing damage, leading to bearing damage. INA bearing in the assembly should be special mold, can't knock at will, in pressure into the shaft only small circle stress, pressure big lap can only big circle stress. When the assembly required by hydraulic pressure or, when pressed in lower die to outside the state level, such as with sloping can lead to bearing the channel for stress damage, and make the bearing produces guide ring.

Bearing in fitted to the rotor dynamic balance on when it's very easy to dynamic balance is generated when iron into internal INA bearing, so it is best to import bearings with the dynamic balance. There are some manufacturer to assembly is convenient, when bearing assembly in indoor apply some oil or grease lubrication effect, but often it is hard to operating personnel quantity control, if oil or grease in bearing indoor integrated leave more, in bearing drive along the axis can easily into the flange bearing internal. Bearing room had better be not besmear oil or grease, if be not besmear is not to control shall not in bearing indoor have a product.

Paint the rust is happens in seal feature dense type of motor, motor in assembling a good voice, but in warehouses, put some time later, abnormal sound of great change motor, remove the INA bearing have serious rustiness phenomenon. Before a lot of manufacturers will think is flange bearing problems, through our continuous publicity, now motor have realized basically is the problem of insulation. The problems mainly because of the volatile acid out insulation in a certain temperature, humidity formed under the corrosive substances, the bearing corrosion cause bearing damage in gully. The problem at the moment is to choose good insulation, and after drying ventilation in a period of time after assembly.
