Matters should be noted that the cylindrical roller bearing burn

The so-called fault is due to cylindrical roller bearings exert impact on the music part of ribs or local roller raceway wheel angle is too large or small part of the fracture loads. The reason for this is that when you install FAG Bearings took a hit. Load is too large. Such as the use bad fall.
Corresponding measures to improve the installation method (thermal loading, use the appropriate tool holder). Correct loading conditions. FAG bearings in place, so that the support ribs.
SUNTHAI bearing injury phenomenon occurs when the card status
The so-called card injuries are due to surface damage Cylindrical Roller Bearings FAG minor burns part in face injury resulting aggregated generated. Slide surface, the rolling surface of the circumferential direction of the linear scar. Roller end of the pendulum linear scar near the card hurt roller end faces of the collar.
Cause SUNTHAI in bearing injury card phenomenon
Load is too large, too much preload. Poor lubrication. Foreign matter bite. Tilt axis deflection of the inner outer ring. Shaft, bad bearing box accuracy.
SUNTHAI measures card bearing injury phenomenon occurs
Check the size of the load. Pre-press should be appropriate. Improved lubricants and lubrication methods. Check the shaft, bearing box accuracy.
The so-called burn in bearing damage state means: wheel bearing raceways, rolling elements and a cage in the rotation until rapid heating discoloration, softening, deposition and damage.
Secondly, it may be too large load (preload is too large). Speed is too large. Clearance is too small. Water or other foreign invasion. If the above two cases are not so that the shaft, bad precision bearing housing, shaft deflection large. See here, I think we all want to know the solution of it, first of all, to study the lubricants and lubrication methods, the election of the bearing lubricant, and its amount, but also to correct bearing selection. To coordinate research, cylindrical roller bearing clearance and preload, and improved sealing means. Check the accuracy of the shaft and the bearing housing.
Test results, if we find cylindrical roller bearing damage and abnormal situation, identify the reasons for the phenomenon of bearing damage, the development of countermeasures. In addition, test results, if there are several defects in the following words, cylindrical roller bearings can not be used again, the need to replace the new bearing.
a. inner and outer rings, rolling elements, cage either a crack appears and debris.
b. inner and outer rings, rolling either a peel.
c. raceway, ribs, rolling a significant injury card.
d. keep the cage badly worn or loose rivets powerful.
e. raceway, rolling rust and have scar.
f. rolling surface, and playing a significant indentation marks on the rolling elements.
g. creep on the inner surface of the inner diameter or outer diameter.
h. overheating discoloration powerful.
Seals and dust cover damage i. Grease sealed bearings to severe.
