What Should You Pay Attention To When Using Composite Bearings, Do You Know A Few?

- Nov 21, 2020-

Bearings are precision parts, so you must be careful when using composite bearings, that is, the use of high-performance bearings (assuming improper use) will not achieve the expected performance and will easily damage the bearings. Therefore, the use of bearings should pay attention to the following points:


First of all, insist on cleaning the bearing and its surrounding environment


Even if an invisible smile enters the bearing, it will increase bearing wear, vibration and noise.


Second, be careful when using equipment


Strong punching is not allowed, hammers are not allowed to directly hit the bearings, and dry bearings are not allowed to transmit pressure through rolling elements.


3. Use appropriate and accurate equipment and tools


Try to use special tools to prevent the use of cloth and short fibers.


Fourth, avoid bearing corrosion


When holding the bearing directly with your hands, please wash the sweat from your hands and apply high-quality mineral oil before stopping the operation. Pay special attention to rust prevention in the rainy season and summer.


However, under certain special operating conditions, especially under light load conditions, the bearing can obtain a longer life than traditional calculations. These special operating conditions make that when the rolling surfaces (tracks and rolling elements) are effectively separated by a smooth oil film and contaminants are restricted, the appearance may be destroyed. In fact, under ideal conditions, the so-called eternal bearing life is possible.


Bearing life


The life of a rolling bearing is defined by the number of revolutions (or working hours at a certain speed). Bearings within this life will suffer initial fatigue damage (flaking or missing) on any of its bearing rings or rolling elements. However, in laboratory experiments or theoretical applications, it can be clearly seen that under the same working conditions, the same bearing has the same theoretical life. In addition, there are several different definitions of the "life" of a bearing, one of which is the so-called "working life", which means that the theoretical life that the bearing can reach before damage is caused by wear and damage, not usually caused by fatigue It is composed of wear, corrosion, seal damage and so on.
