The metallurgical material was the main factor that affected the early failure of the one-way needle roller bearing. With the improvement of metallurgical technology, the proportion of raw material quality in the failure analysis of one-way needle roller bearings has been significantly reduced, but it is still one of the main factors of the failure. Raw material is still the main considerations in the success of needle roller bearings .

Needle bearing vibration has significant affection on its failure. For example, peeling, indentation, corrosion, crack, wear, etc. are all reflected in the one-way needle bearing vibration detection. Vibration range can be measured by special vibration measurement device (frequency analyzer and vibration meter, etc.); Through the frequency distribution can be inferred from the details of the abnormal vibration measured by the use of one-way needle roller bearings or sensor installation location. There measurement size of each machine need to be analysis first before size determination.

Cleaning of Needle roller bearing

Rough cleaning and fine cleaning are necessary. Put a metal net to the container bottom to avoid the needle bearing become dirty. When rough cleaning, if the dirt things rotate together with needle roller bearings, the rolling surface will be damaged. A brush is helpful to remove the attachment of the bearings. After all done, then turn to fine cleaning process.
