NSK Bearings equipment for regular maintenance, operation and external parts replacement was dismantled thrust roller bearings for inspection, required in order to determine whether this bearing parts can be used again and record usage of good and bad. Should carefully investigate and record split down the bearing and appearance of the situation. In order to understand and investigate remaining amount of lubricant, after the sampling, to a good wash bearings. Test results, if found bearing damage and abnormal situation, please follow identify the reasons for the phenomenon of bearing damage, develop countermeasures. In addition, test results, if there are several flaws words below, bearing it can not be used again, you need to replace the bearings.
NSK Bearings before damage can be achieved in real life by bearing wear, damage is usually not caused by a tired, but by bearing wear, erosion, seal damage and other causes. Yet no matter in laboratory tests or in actual use, can significantly seen in the same work under the premise of the appearance of the same thrust roller bearings, generally speaking, a third of the bearing damage due to fatigue damage , bearing another third due to poor lubrication guide, the other third due to contaminants entering the bearing guide or the installation mishandled.
Improve the accuracy of rotation of the bearing, NSK Bearings reduce the vibration and noise experimental studies have demonstrated improved precision bearing rotation, vibration and noise reduction were associated with deviation from circular rings significantly reduces a great relationship. This is to improve the entire bearing capacity to create good conditions. Furthermore, thrust roller bearings for rolling bearing raceway super finishing except if the crown, but also can improve the bearing capacity. Super finishing work greatly improved bearing performance and life, because there are so many beloved ultra-fine features and effects, so more and more bearing rings finishing of all ages.
1, the bearing removed for inspection, first with photography and other methods to make the appearance of records.
2, in addition, to confirm the remaining amount of lubricant and lubricant samples, and then cleaning bearings.
3, the bearing cleaning of rough wash and sperm washing and can be placed in the bottom of the container used metal grid.
1), coarse wash, brush, etc. used in the oil or grease removal adhesive material. At this point if rotating bearings in oil, attention and other damage due to foreign objects rolling surface.
2), sperm washing, in the oil slowly rotating thrust roller bearings, to be carried out carefully.
4, commonly used cleaning agents for the neutral water diesel or kerosene, is sometimes necessary to use warm lye. No matter which cleaning agents, filter should always be kept clean.
5, cleaning immediately after NSK Bearings rust coating on grease oil or rust.
