Match Usage Of The Bearing
Oct 22, 2018

match usage of the bearing 


First, the choice of cooperation


The inner and outer diameters of the rolling bearing are manufactured to standard tolerances. The tightness of the inner ring of the bearing to the shaft and the outer ring to the seat hole can only be achieved by controlling the tolerance of the journal and the tolerance of the seat hole. The inner ring of the bearing and the shaft are matched by a base hole, and the outer ring of the bearing and the seat hole are made by a base shaft.


The correct choice of fit, you must know the actual load conditions of the bearing, operating temperature and other requirements, but in fact it is very difficult. Therefore, most of the cases are based on the use of lint selection.


Second, the load size


The amount of over-win between the ferrule and the shaft or casing depends on the size of the load, the heavier load uses a larger over-win, and the lighter load uses a smaller over-win.


Precautions for use


Rolling bearings are precision parts, so they need to be cautious when using them. Even if high-performance bearings are used, if they are not used properly, the expected performance will not be achieved. Therefore, the following matters should be noted when using bearings:


First, keep the bearings and their surroundings clean. Even very small dust entering the bearing can exacerbate bearing wear, vibration and noise.


Second, the installation should be careful and careful, does not allow strong stamping, can not directly hit the bearing, does not allow the pressure to pass through the rolling body.


Third, use the correct installation tools, try to use special tools, and try to avoid the use of cloth and short fibers.
