What Should Be Paid Attention To When Using Compound Bearing
Sep 05, 2018

The bearing belongs to the fine part, so it is very careful when applied. Even with high performance bearings, if used improperly, can not arrive the expected performance effect, and easily make the bearing damage. Therefore, the following items should be noted when applying the bearing:


1. Keep the bearing and its surrounding environment clean, even if invisible dust from the naked eye enters the bearing, it will increase the wear, vibration and noise of the bearing.

2. Use the device carefully and carefully, not allowing strong stamping, not allowing the hammer to hit the bearing directly, not allowing the pressure to pass through the rolling body.

3. Use appropriate and precise device tools, use special tools as far as possible, and try to prevent the use of cloth and short fibers.


4. Avoid the rust of the bearing. When you take the bearing directly with your hands, you should flush the sweat in your hands, and then stop the operation with high quality mineral oil. You should pay special attention to rust in the rainy season and summer. However, under some special operating conditions, the bearing can achieve a better life than conventional calculation, especially under the condition of light load. These special operating conditions are when the rolling surfaces (orbits and scrolls) are effectively separated by a smooth oil film and the appearance of damage that can be caused by contaminants. In fact, under ideal conditions, the life of the so-called eternity bearing is possible.


5.the service life of bearing, the life of rolling bearing with revolution (or in the hours of work under a certain speed), the definition: within the life of the bearing, should be in any of its bearing ring or rolling body attack on initial fatigue damage (spalling or defect). However, whether in laboratory experiments or in theoretical application, it is obvious that the theoretical life is very different in the same working conditions. In addition there are several different definitions of bearing "life", one of which is known as the "service life", it represents a certain bearing before damage can arrived in the theory of life is made up of wear and tear, damage caused by usually is not tired, but by abrasion, corrosion, the reason such as sealing damage forms.
