In addition to excellent quality, FAG bearings are also very precise parts. They are high-performance bearings. If they are used improperly during use, they will not achieve the expected performance, and it is easy to damage the bearings. Already noted. In addition to lubrication, FAG bearings need to pay attention to those aspects of use?
First, use the installation carefully
Strong stamping is not allowed. It is not allowed to directly hit the bearing with a hammer. It is not allowed to transmit pressure through the rolling elements.
Second, use appropriate and accurate installation tools
Try to use special tools and try to avoid using cloth and short fibers.
Third, try to keep the FAG bearing and its surroundings clean
Even if the smiling dust that is invisible to the naked eye enters the bearing, it will increase the wear, vibration and noise of the bearing.
Fourth, to prevent corrosion of FAG bearings
When taking FAG bearings directly by hand, wash off the sweat on your hands and apply high-quality mineral oil before handling. Pay special attention to rust prevention during the rainy season and summer.
Under certain operating conditions, FAG bearings can achieve longer life than traditional calculations, especially at light loads. These special operating conditions are when the rolling surfaces (tracks and rolling elements) are effectively separated by a lubricant film and the surface damage caused by contaminants is limited. In fact, under ideal conditions, so-called permanent FAG bearing life is possible.
When disassembling the FAG bearing for inspection, first record the appearance of the bearing, confirm the residual amount of the lubricant, and then wash the bearing after sampling the lubricant for inspection. As a cleaning agent, gasoline and kerosene are commonly used.
The FAG bearings removed are cleaned and cleaned separately, placed in a container, and placed on the bottom of the metal mesh so that the bearings do not directly touch the dirt of the container. In rough cleaning, if the bearing is rotated with dirt, it will damage the rolling surface of the bearing and should be noted. In the rough cleaning oil, use a brush to remove the grease and the adhesive. After it is almost clean, it is transferred to the fine wash.
Fine washing is to carefully clean the bearing while rotating it in the cleaning oil. In addition, the cleaning oil should always be kept clean.
Bearing inspection and judgment: In order to judge whether the removed bearing can be used, it should be checked after the FAG bearing is cleaned. Check the raceway surface, the rolling surface, the state of the mating surface, the wear of the cage, the increase of the bearing clearance, and the damage and abnormality that are irrelevant in dimensional accuracy. For non-separable miniature ball bearings, use one hand to support the inner ring horizontally and rotate the outer ring to check if it is smooth.
Separate bearings such as tapered roller bearings can be inspected separately for the rolling surfaces of the rolling elements and the outer ring.
