Needle roller bearings common faults

Needle roller bearings common fault sources: this website the author: the administrator to release time: 2018 - 10 - 18 09:36:00 views: 1 needle roller bearings bearing the common breakdown surely everybody knew! There are many products in our daily life can use bearing products. Due to the application of bearing products is more and more widely, manufacturer of bearing too much. Needle roller bearing is applied more widely a bearing products. Sometimes in use process, needle roller bearings will happen some faults, now I will introduce some common faults of needle roller bearings. Only by understanding the reason of the failure to solve the problem, you will go with me to know about the below! 1. Needle roller bearings and the roller both inner and outer ring raceway surface under the role of the periodic pulse load, resulting in a periodic change of the contact stress. When stress cycle number reach the specified value in the rolling element bearings, their work within or on the surface produce the phenomenon of fatigue spalling. 2. Burn the needle roller bearings on the raceway and rolling body heat tint. Burns is usually the cause of insufficient lubrication, lubricating oil quality does not conform to the requirements or metamorphism, and bearing assembly too tight. 3. Needle roller bearing raceway and roller contact surface appear uneven pits, needle roller bearings produce plastic deformation. The reason for this is that needle roller bearings in large under static load or shock loading, local stress on the surface of the work of more than material yield, this kind of situation usually happened in the low-speed rotation of the bearing. 4. Needle roller bearing race cracks may be the cause of needle roller bearings with tight, make foreign or needle roller bearing inner ring of roller is loose, bearing deformation, inclusive of installation of needle roller bearings and poor surface finish. 5. Insufficient lubrication needle roller bearings, roller broken, seat skew, etc. 6. Retainers metal adhesion on the rolling body possible reason is that roller was stuck in a cage. 7. Seat ring raceway serious wear and tear, may is a circle into foreign body, lack of lubricating oil or lubricating oil brand is not appropriate. After the above introduction, everyone is common fault for needle roller bearings have some preliminary understanding? No matter what product failure occurs, only to understand the cause of the problem can solve the problem, needle roller bearings, of course, is no exception. What about needle roller bearings of common faults are given to everybody here, our company produce all kinds of roller products, if you want to know more can we needle roller bearings manufacturer calls for understanding, we will always welcome your call!
