When using composite bearings should pay attention to what place
Bearings are fine parts, so when you use requires considerable caution. Even the use of high-performance bearings, if used improperly, it can not reach the expected performance results, and easy to make roller slide rails damage. Therefore, the use of bearings should pay attention to the following:
First, adhere to clean bearing and its surroundings, even invisible dust into the bearings, will increase wear, vibration and noise of the bearing.
Second, the use of the device to be careful, do not allow a strong punch, does not allow a direct hit with a hammer bearing allowed after rolling the delivery pressure.
Third, the application of appropriate and accurate tool means, try to use special tools, trying to prevent the use of cloth and stuff like short fibers.
Fourth, to avoid corrosion of bearings, bearing directly by hand when handling, plenty to wash hands sweat, and coated with high-quality mineral oil and then suspended operations during the rainy season and summer with particular attention to rust. However, in certain special operating conditions, bearings can achieve better at traditional computing life, especially under light load conditions. These special operating conditions that, when the outer rolling surface (track and rolling element) are effectively separated and limit pollutants that might lead to a smooth film destruction. In fact, under ideal conditions, the so-called permanent bearing life is possible.
Fifth, the DU-H half bushing life, the life of rolling bearings with number of revolutions (or number of hours of work under a certain speed), defined: in this life bearing within, should any attack on its rolling element bearing ring or initial fatigue damage ( peeling or chipped). However, both in laboratory experiments or in the Theory, we can clearly see the appearance under the same working conditions identical bearings theoretical life different. There are also several different definitions of bearing "life", one of the so-called "working life", it indicates the theoretical life of a bearing can be reached before the damage is usually not damaged by the white ptfe solid lubricant type bushing,bearing,wear plate,pad and tear caused by fatigue, but consists of wear, corrosion, seal damage and other reasons.
