How to prevent premature failure of INA stainless steel bearings

Bearings in the process of use for various reasons, will cause failure problems, then what are the failures of stainless steel bearings? We classify the failure modes of rolling bearings. These forms are the most basic three forms of rolling bearing failure. There are many reasons for bearing failure. All the factors affecting the design and manufacturing process will be related to the failure of the INA bearing. It is difficult to judge by analysis. In general, it can be considered and analyzed in terms of both usage factors and internal factors.

Wear, poor lubrication, intrusion of impurities and dust can cause wear and tear, which causes the INA bearing to lose its rotational accuracy and fail, which is the external cause. We should pay attention to maintenance and cleaning.

When the bearing speed is low or intermittently oscillated, fatigue pitting does not generally occur. At this time, the bearing is often plastically deformed due to excessive static load or impact load, which causes the stainless steel bearing to fail. This is the problem of work intensity. It is necessary to first match the strength of the bearing, that is, what is the speed required for your work, and choose the bearing that matches it.

(1) Surface oxide layer

The surface of the steel under transient high temperature acts on the oxygen in the air and rises into a very thin (20-30 nm) thin layer of iron oxide. It is worth noting that the thickness of the oxide layer is corresponding to the test results of the total thickness of the surface-grinding metamorphic layer. This shows that the thickness of the oxide layer is directly related to the grinding process and is an important indicator of the quality of the grinding.

(2) amorphous layer

When the instantaneous high temperature of the grinding zone causes the surface of the workpiece to reach a molten state, the molten metal molecular flow is uniformly applied to the working surface, and is cooled by the base metal at a very fast speed to form a very thin layer of amorphous state. Organizational layer. It has high hardness and toughness, but it is only about 10 nm and is easily removed in precision grinding.https://www.supplyforever.com/
