Failure manifestations of bearing damageIf the bearing has reached the middle and late fault state, its characteristics are very obvious. Generally, it is realized as bearing damage, such as shaft holding, burn, sand frame spallation, raceway, bead wear,
The types of machinery are different, the service conditions of bearings will be different, and the performance requirements are not only the same, but generally speaking, there are no less than two bearings on a shaft. Moreover, in order to facilitate ax
CNC turntable is widely used in various CNC milling machines, boring machines, various vertical turning, vertical milling and other machine tools. In the design of turntable, there are several types of bearings used:What are the common bearing types in NC
The manufacturing process of steel ball is the key factor to determine its service life. If there are defects in the surface or internal manufacturing of the steel ball, such as shrinkage, crack, transgranular, etc., it will not only reduce the performanc
Why is the bearing burned or locked?1. Improper selection of bearing clearance.For example, C3 group clearance should be selected, but ordinary group clearance is actually selected. As the bearing will continue to accumulate heat during operation, the sha
Although bearings are often encountered, many people do not know what the installation skills of bearings are. This is the way of bearing installation. Many videos may also be introduced at present. However, we should carry out different installation meth
Fatigue peeling is the flake peeling of bearing surface caused by rolling fatigue. When the bearing works, the load on the rolling body and inner ring (or outer ring) is not constant, but changes with the running cycle of the bearing. This load is alterna
When the center line of the shaft does not coincide with the center line of the bearing seat and has angle error, or when it is bent or tilted due to the force of the shaft, the axis of the inner and outer rings of the bearing will be inclined. At this ti
The more common cause of bearing rupture is man-made. For example, hard knocking during disassembly and assembly and hard particle impurities invading the interior of the bearing may cause the inner and outer rings and cages to crack. The clearance adjust
Bearing is a rotary part supporting journal or shaft. According to the working principle of bearing, it can be divided into rolling friction bearing (rolling bearing) and sliding friction bearing (sliding bearing). Sliding bearing: if a lubricating film c
