The performance of the shaft diameter in direct contact with the shaft tile to prevent adhesion and the formation of boundary lubrication. The material factors that affect the friction compatibility of the friction sub-materials are the ease of metallurgical composition ...

For the rotating ring and rolling body through the bearing area of each point when the contact load and stress is changing; and in each contact point of the contact load and stress is pulsating cycle characteristics...

Cylindrical roller bearing if in good continuous rotation state will issue a low whine or humming sound. If a sharp hiss, squeak and other irregular sound, often indicates that the bearing is in bad continuous rotation condition, sharp squeak noise may be due to...

Cause the bearing cage breakage reasons have bearing lubrication insufficient lubricating oil or grease finished, did not add maintenance in time, lubricating oil or grease with the wrong mark, bearing impact load impact load in the fierce...

Small localised bearing raceways and rolling elements may be damaged. In operation, localised damage is due to operational or mounting errors. Vibration frequency analysis can identify damaged cylindrical roller bearing components...
