Bearings are an important part of modern machinery and equipment, and the amount is astonishing. Take a car as an example, a car generally needs 100 to 150 bearings to ensure normal driving.
The main function of the bearing is to support the mechanical rotating body, reduce the friction coefficient during the movement, and ensure its rotation accuracy at the same time. In the process of use, the premature damage of the bearing and the short life span trouble workers in every industry. Today, I will share with you some methods and techniques for extending the service life of bearings.
According to the investigation, poor lubrication is the most important cause of premature bearing damage. 50% of the premature damage is caused by poor lubrication. Specifically, it includes: failure to add lubrication products in time, and selection of lubrication products. Wrong type or not filling in place, incorrect lubrication method, etc.
In this regard, our advice is: before lubricating the bearing, you must choose the correct lubrication product and use the correct way to fill it.
Fatigue damage is another common way of damage to bearings, and 34% of the cases of premature damage are caused by this. The main causes of bearing fatigue are: long-term overload operation of the bearing, failure of the bearing to be repaired in time or improper maintenance, aging of the equipment, and so on.
Here, our advice is: select the appropriate bearing type, check regularly and replace the fatigue bearing in time.
The bearing life reduction caused by improper installation accounts for about 16%. Generally speaking, it mainly includes the following two specific reasons: First, excessive force is used during installation. For example, some workers will hit the bearing with a hammer. The bearing damage is actually very large, and it is easy to cause its deformation. Secondly, there are deviations in the installation process, and the bearing is not installed, causing the bearing clearance to be too small, or the inner and outer rings are not concentric.
In this regard, our suggestion is: choose an appropriate or professional bearing installation tool before installation, and don’t forget to use a special instrument to detect it after installation.
The meaning of pollution is that impurities such as dust and metal shavings enter the inside of the bearing. This is also a non-negligible cause of premature damage to the bearing, accounting for about 14% of all causes. Opening the package too early before use will cause internal pollution. At the same time, the dirty and messy working environment during the installation process will cause the bearing to pollute.
In response to this phenomenon, our advice is: it is best not to unpack the bearing before use; at the same time, keep the installation environment clean when installing, and the bearings used should be cleaned regularly to prevent pollution; enhance the bearing Sealing means.
