Bearings are precision parts and only some of the bearings are damaged in practical applications.
Most of the bearings are damaged for many reasons - beyond the original estimated load, non-effective seals, too tight bearing clearance caused by too small bearing clearance. Any of these factors have their particular type of damage and leave a special mark of damage. Therefore, inspecting the bearing of the damaged shaft, in many cases, its possible cause can be found. In general, one-third of the bearing damage is caused by fatigue damage, and the other third is caused by poor lubrication. The other third is due to contaminants entering the bearing or improperly installed.
However, these types of damage are also related to industry. For example, most of the pulp and paper industry is due to poor lubrication or contamination resulting in bearing damage rather than material fatigue. Bearings are precision parts, so they require a very cautious attitude when used. Even if high-performance bearings are used, if they are used improperly, the expected performance will not be achieved and the bearings will be damaged easily. Therefore, the following matters should be noted when using bearings:
1. Keep the bearings and their surroundings clean. Even if tiny dust that is invisible to the naked eye enters the bearings, it will increase the wear, vibration and noise of the bearings.
Second, use the installation carefully and carefully Do not allow strong stamping, do not allow the hammer to directly hit the bearing, not allowed to pass the pressure through the rolling elements.
Third, the use of appropriate and accurate installation tools Try to use special tools, try to avoid the use of cloth and short fibers and the like. Fourth, to prevent the corrosion of the bearing When taking the bearing directly by hand, you should wash the sweat on your hands and apply it with high-quality mineral oil before handling. In the rainy season and summer, pay special attention to rust prevention.
