Ball bearing is a precision part, so it is required to be very cautious when using, that is, it is a high performance ball bearing. If it is not used properly, it can not achieve the desired performance effect, and it is easy to damage the ball bearing. Therefore, attention should be paid to the following items when using ball bearings.
One. To keep the ball bearings and their surroundings clean, even if the unseen smile dust enters the ball bearings, it will also increase the wear, vibration and noise of the ball bearings.
Two, use carefully when installing, do not allow strong stamping, do not allow direct percussion of ball bearings with hammers, do not allow transmission through the rolling body pressure.
Three, use appropriate and accurate installation tools, try to use special tools, and try to avoid the use of cloth and staple fibers and the like.
Four, to prevent the rust of ball bearings, when taking the ball bearings directly with hands, we should wash the sweat from the hands fully, and then apply the high quality mineral oil to the operation. In the rainy season and in summer, we should pay special attention to the rust prevention. However, under certain special operating conditions, ball bearings can get longer life than traditional ones, especially under light load conditions. These special operating conditions are that when the rolling surface (track and roller) is effectively separated by a lubricating oil film and limits the surface damage that may be caused by the contaminant. In fact, under ideal conditions, the life expectancy of permanent ball bearings is possible.
There are many reasons for the damage of most ball bearings - beyond the previously estimated load, the clearance of small ball bearings resulting from the non effective seal and tight fit. Any factor of these factors has its special damage pattern and will leave special damage marks. Therefore, inspection of damaged ball bearings can be found in most of the cases. In general, 1/3 of the ball bearing damage leads to fatigue damage, the other 1/3 causes poor lubrication, and the other 1/3 causes the contamination into ball bearings or improper installation.
However, these damage patterns are also related to industry. For example, the pulp and paper industry is mostly caused by poor lubrication or contamination, rather than fatigue due to fatigue of ball bearings.
