In order to better to best use of FAG bearings mechanical device efficiency, bearing selection have a direct relationship with the stable operation of the device. Bearing grease to select required from the following areas for consideration:
1. Rust preferably insoluble in water. Fats and oils should have good adhesion, the use of FAG bearings oil required has a rust-proof effect. And steel exterior form an oil film.
2. lead to disclosure. During normal operation, grease the machine will become soft. Oil will be dumped to the FAG bearings. If the mechanical stability of the grease is insufficient, in the operation of, would make oil SOAP mechanical disintegration in the structure, causing oil to be destroyed, and thus lose lubrication.
3. the bearing in operation, maintenance of FAG bearings and lubricant oil seal is required from external pollution barrier. Regardless of debris or moisture cannot penetrate FAG bearing, caused damage to its case. Correct device later played important factors for maximum bearing life. At the same time, required attention to cleanliness of bearings, bearing selection and correctness of the choice of appropriate equipment and maintenance tools. In addition, the bearings are necessary to prevent pollution by contaminants and moisture, and ensure the correct device and lubrication. Column design bearings, oil seals, lubricants and lubrication cycle of the situation, as well as specialized Yang are important and plays the same role.
Of course, FAG bearings if the work speed is very low, but also working in polluted and humid environment, preferably in FAG bearings are filled with grease.
Especially in the vertical axis or axis angle into an application. Grease also has sealed, and prevents pollutants, moisture or moisture effects on bearing. But if the excess of grease will cause the FAG bearing temperature rise, especially in high speed applications. In most cases, only in the first stage can be completely filled with grease bearings, but fills only the right amount of grease in the bearing and have a certain amount of free space. Completely before reaching the working speed, excessive amounts of grease must be discharged outside of FAG bearings in the run-in phase, so that the right amount of grease in the bearing. When the temperatures drop significantly, grease bearing has running, and evenly distributed in the bearing arrangement.
