Several fault analysis of AXK0821 flat needle roller bearing

AXK0821 flat needle bearing source of several failure analysis: this website the author: the administrator to release time: 2015 - 08 - 21 11:07:11 views: 0 axk0821 plane said several fault analysis of needle roller bearing to bearing equipment, as part of the nc machine tools, machine tool working without bearing, bearing a diversity of today, the different types of bearings have different functions. AXK0821 flat needle roller bearing is a kind of needle roller bearing, which may occur in using the fault? Now we are under the simple analysis. Bearing in operation Cha Cha noise: this is basically the length of the roller is very long, makes the end face of roller and rotary bearing seat up and down the rolling friction and make the Cha a Cha noise. Under normal circumstances, AXK0821 flat needle bearing friction roller not race, if the length of the roller is very long, the noise due to friction. Either bearing, there is a sound, we can't look down upon this kind of phenomenon, need to stop running jiaxing needle roller bearing, check the reason and eliminate it. On the other hand, the needle roller bearing raceway surface defects: because of the raceway serious uneven or plane distortion; After subjected to overloading, the partial pressure is too large, more than raceway contact strength; Because of the impact point or long-term overworked, fatigue damage; Raceway rust, cracks and gradually expand. 2, raceway surface appear more rules of line indentation analysis: the main reason is that rotary bearing static vibration in the location specified for a long time, such as truck crane for a long time in the rugged terrain, axial clearance increases, the impact roller busbar raceway, resulting in a equal spacing of line indentation. This article mainly analyses all flat needle roller bearing are introduced in use all kinds of problems, causes of the problem are also different, hope you targeted to solve the problem. If others can't solve the problem, can go to contact our needle bearing, we not only is specialized in manufacturing bearing factory, also has a wealth of experience in dealing with problems.
