FAG bearings in burn

Fracture refers to because of needle bearing raceway wheel rim or local part of the roller Angle are exerted impact or excessive load and a small number of fracture. Appear this kind of circumstance is the cause of needle roller bearing has taken a knock during installation. The load is too large. Using bad fall, etc. The corresponding measures to improve the installation method ( Adopt the hot charging, using the appropriate tool holder) 。 Correct the load conditions. Needle roller bearing installed, supporting to guard. Needle roller bearing card injury occurs when the state of the so-called card wounded is because the needle roller bearing in the sliding surface of part of the minor burns summary of surface damage. Slide face, rolling surface circumferential direction of linear scars. End of the roller set linear scar near the end of the roller shaft torus card. Needle roller bearing phenomenon the reason card hurt too much too much load, preloading. Bad lubrication. Foreign body nip. The inner ring of the outer ring tilt, the deflection of shaft. The precision of shaft, bearing box. Needle roller bearing card injury occurs when the size of the measures to check the load. Preloading is appropriate. Improve lubricant and lubricating method. Check the shaft, the precision of the bearing housing. Bearing state of burn injury refers to: the bearing raceway wheel, roller and cage in the rotation sharply fever until discoloration, softening, deposition and damaged. The second is probably too big load ( Preloading is too big) 。 Speed is too large. Clearance is too small. With water or other foreign matter invasion. If the above two cases are not the shaft, the accuracy of bearing box, shaft deflection. See here, I think everyone wants to know the solution, first of all, to study lubricants and lubrication method, choose the right bearing lubricant, and its dosage, and the selection of the bearing must be corrected. Study to cooperate, FAG bearing clearance and preloading, and improve the sealing device. Check the shaft and the precision of the bearing housing. Of course, if you have any experts beside you, let him follow you learn best operation!
