Many large industrial enterprises in today's society will first consider SKF bearings when choosing bearings, which shows the global influence of SKF bearings, SKF bearings are stable in use, low failure rate, longer life, but inevitably will encounter some problems in the use process.
The noise problem of SKF ball bearings is a problem that many people want to solve, ball bearings will vibrate violently when working, many times the vibration of ball bearings will appear very noisy, which has a very bad impact on people's hearing and mood, SKF bearings noise general reasons may be:
First, the bearing aging is serious, excessive load leads to the rapid aging of SKF bearings, there is a loss inside the bearing, and the severe friction produces a lot of noise!
Second, the assembly process has problems, the correct assembly of SKF bearings can ensure the normal use of bearings, if there is misalignment, or assembly errors may lead to noise and other situations, serious even accidents!
Third, SKF bearings are not fully lubricated, do not get good lubrication, the friction between the bearing and the bearing sleeve increases, easy to produce noise and other problems.
SKF bearings are precision parts, so they require considerable caution when using them, that is, high-performance thrust ball bearings are used, and if they are used improperly, they cannot achieve the expected performance effects, and it is easy to damage the bearings. Therefore, the use of bearings should pay attention to the following matters:
Even tiny dust that is invisible to the naked eye enters the bearing, which can increase the wear, vibration and noise of the bearing.
Strong stamping is not allowed, direct hammering of the bearing is not allowed, pressure transfer through rolling elements is not allowed. It is desirable to open the SKF bearing package again at the time of mounting. When the general grease is lubricated, the bearing is not cleaned and the grease is directly filled. When lubricating oil, it is generally not necessary to clean, but bearings for instruments or high-speed should be cleaned with clean oil to remove rust inhibitors applied to the bearings. The bearing with the rust inhibitor removed is easy to rust, so it cannot be placed arbitrarily.
SKF bearings will make some noise after running for a period of time, which is normal, but if the sound is very noisy and continuous, it means that the bearing has a noise problem, why does the bearing have noise?
Any of the inner and outer rings and rolling elements are peeled; Rusted and scarred raceway surfaces and rolling elements; The raceway surface, flange and rolling element have significant jams; There are significant indentations and marks on the rolling surface and rolling body; Any of the inner and outer rings, rolling elements, and standoff frames has cracks and debris; superthermal discoloration; The sealing ring and shield of the grease sealed bearing are seriously damaged; severe wear of the cage or loose rivets; There are creeps on the inner diameter surface of the inner ring or the outer diameter of the outer ring, etc.
