The installation method main point that the rolling bearing heats:
Heat the main point of installing law:
The temperature heated should be controlled properly, the temperature too high bearing will be damaged, the expansion of one set of circles of hypothermia is insufficient, the result is not prominent. 80- The intersection of heating and the intersection of temperature and resulting the intersection of inner circle and the intersection of heat and expansion of internal diameter of 1000 ℃, this generally over to full of bearing of quantity for to have speech, it is enough. Inquire about the software in bearing type of the car
As soon as reach the required heating temperature, should install as soon as possible, so as not to cool and install the difficulty. Inquire about the software in bearing type of the car
The bearing shrinks while cooling in the width direction too, so should exert certain pressure and compress tightly the inner circle to the shoulder at the time of installation, and by extremely thin filling in one chi of attachment and measuring after cooling, the interval has appeared among terminal surface of inner circle and axle shoulder. In a word, butterfly’s writings is required skilledly, fast and accurately. Inquire about the software in bearing type of the car
The installation method that the rolling bearing heats:
When the internal diameter of the bearing is greater than 70mm, whether to or cooperated and is full of bigger or not, adopt heating law to make the bearing hole swell, installation save effort save time in this way, avoid too because the intersection of application of force and too big and damage that cause.

It is heating temperature that need to control at this moment, generally heat the bearing to 80 ℃, it is 100 ℃ highest. It is enough. Exceed, will cause bearing take place the intersection of flash back and phenomenon by 120 ℃, cause sets of hardness of circle lower to the precision lowering. Bearing enterprises navigate
