Rust directly by hand to take to prevent bearing SKF bearings, to fully wash away sweat on his hand, and coated with high quality mineral oil before operation, paying particular attention to rust in the rainy season and summer. However, in some special operating conditions, calculation of bearings can be obtained more than traditional life, especially under light load conditions. These special operating conditions is that as you scroll through the surface (track and rolling) were effectively separated by a lubricant film and limit pollutants may cause surface damage. In fact, in ideal conditions, the so-called permanent bearing life is possible.
Avoid unexpected early bearing failure. Installation conditions is one of the leading factors in the use, the bearings are installed are not suitable, they result in packages bearing stress changes between the various parts of, in a State of abnormal functioning of the bearing and early failure. According to the FAG bearing installation, use, maintenance, maintenance of technical requirements, in the operation of bearings to withstand the load, speed, temperature, vibration, noise monitoring and inspection and lubrication, unusual now to find reasons to adjust, bring it back to normal.
Smooth melodious voice, high-pitched squeaking noise may be due to insufficient clearance caused by improper lubrication of the bearing can also cause metal sound. Notch on the bearing outer race track will cause vibration. If percussion scars caused by the devices generate noise, this noise bearing different speed levels. If you have intermittent noise, and scroll through the parts may be damaged, the sound occurs when damage to the surface of launch dates, if bearing hissing "sound pollution often cause serious damage to the bearings and noise caused irregular.
Due to operation or installation errors, few of the raceways and rolling elements may be damaged. Running, NSK bearings scroll past the damaged parts will have a specific frequency of vibration. Vibration frequency analysis to identify damaged bearing parts. While bearing no wave deformation, vibration may occur. Between the bearing ring and the bearing seat or shaft drive fit case, bearing rings are likely to tie in with the adjacent parts of the shape is distorted. If there is a distortion, in operation may produce vibrations. Therefore, the drive shaft bearing blocks and machined to the tolerances required are very important.
When scrolling changes the load resulting from vibration. When a radial load when the load on a bearing, the number of rolling load bearing in operation may vary slightly, that is: this has led to bias of the load direction. The resulting vibration is inevitable, but you can mitigate by axial preload, load all the rolling (not for cylindrical roller bearings).
