Why bearings fail prematurely
Author:admin Date:2022-05-27
Oil-free bearing is an important part of contemporary mechanical equipment. The main function of oil-free bearing is to support the mechanical rotating body, reduce the friction coefficient during the movement, and ensure its rotation accuracy. So, how to extend the service life of oil-free bearings? Let's take a look at it together!
1. Fatigue failure of oil-free bearings is a common damage method for bearings, and 34% of premature failures are caused by this. Oil-free bearings are overloaded for a long time, the bearings are broken without timely maintenance or improper maintenance, and the equipment is aging. Select the appropriate type of oil-free bearing, check regularly and replace the fatigued oil-free bearing in time.
2. Improper installation of oil-free bearings. The bearing life is reduced by about 16% due to improper installation. Excessive force during installation. For example, some staff will hit the composite bearing with a hammer. This damage to the bearing is actually very large and it is easy to cause its deformation. Secondly, there is a deviation in the installation process, and it is not installed in the bearing position, which causes the bearing clearance to be too small, or the inner and outer rings are not concentric. Therefore, it is necessary to select appropriate or professional oil-free bearing installation tools before installation, and do not forget to use special instruments for testing after installation.
3. The contamination of oil-free bearings means that impurities such as dust and metal chips enter the inside of the bearing, which is also a non-negligible cause of premature bearing damage. Opening the package too early before use will cause internal contamination, and at the same time, the working environment during installation will cause contamination of oil-free bearings.
