It is necessary to choose an appropriate method for cleaning according to the nature of the rust-proof object and the prevailing conditions.
Of course, it is also related to the surface finish of the drawn cup needle roller bearings. The method to avoid rust caused by hand sweat is that the production personnel should wear gloves, finger cots, or use special tools to pick up the bearing when installing the drawn cup needle roller bearing. The corrosion resistance. Generally, the oxygen concentration is poor and the battery is corroded. The sweat film will cause electrochemical effects on the bearing, corrode the bearing, and produce embroidery.
However, human sweat is inevitable. The corrosion of drawn cup needle roller bearings is due to its own materials, because it is made of bearing steel, so its chemical composition and structure may be oxidized by air to become embroidered. Do not use it at will Hand touch the bearing surface. In addition, the composition and pH value of the solution that touches the surface of the drawn cup needle roller bearing; the temperature and humidity of the environment where the bearing is stored; various environmental media that touch the surface of the bearing will also directly affect the drawn cup needle roller bearing. In order to prevent rusting of drawn cup needle roller bearings, the first thing to pay attention to is to clean the surface of the bearing.
Due to the influence of various connotations and external elements, drawn cup needle roller bearings may show corrosion, so before adopting anti-rust methods, it is necessary to fully understand the specific causes of the problem. The thickness of the oil film can be controlled to prevent The temperature or viscosity of the rust grease is reached. When sweat touches the bearing surface, it will form a layer of sweat film on the bearing surface. Then we can select useful solutions in a targeted manner.
In addition, human hand sweat can cause corrosion of the needle roller bearings in the stamped outer ring, because human sweat is a colorless, transparent or light yellow liquid with a salty taste and weak acidity. Generally, solvent cleaning is more common, chemical treatment cleaning method and mechanical cleaning method. The exterior of the drawn cup needle roller bearing can be dried with filtered dry compressed air after being cleaned and cleaned, perhaps with a drier at 120-170 degrees Celsius, or with clean gauze. In addition to containing sodium, potassium, calcium, and magnesium In addition to salt, it also contains a few organic acids such as urea, lactic acid, and citric acid

It has changed our lives.We use at least 200 bearings every day in our lives. The real processing is much more complicated than this, and the steps can sometimes reach as many as 70 steps. Clutch Release Bearing manufacturers The heat treatment process is the high temperature treatment of the bearing ring after forging and turning, which directly affects the uniformity of carburization in the bearing ring, can improve the wear resistance and hardness of the bearing, and also affects the reliability and life of the bearing..
In addition, the quality of the forging process will directly affect the utilization rate of raw materials, thereby affecting production costs. After the raw material is forged, the bearing ring blank is formed. At the same time, the organization structure of the raw materials becomes denser and the flow linearity becomes better, which can improve the reliability and service life of the bearing.
Rolling bearing manufacturers in the rolling bearing production process, the key is the following links: The forging link is an important link to ensure the reliability and life of the bearing. Seemingly simple mechanical analysis, the processing requirements are very high, especially the precision requirements of the heat treatment, forging, and grinding links are very strict, so the general bearing processing enterprises are very powerful. Important link.
Megosztás a facebookonNeedle roller bearings can be divided into the following categories according to their structure: sealed drawn cup needle roller bearings with inner ring needle roller bearings and without inner ring needle Clutch Release Bearing roller bearings/no inner ring without holder needle roller bearings, with holding frame and without holding frame .
The frame is filled with needle roller bearings, needle roller bearings without ribs, self-aligning needle roller bearings, combined needle roller/ball bearings and needle roller bearings with knurled outer rings, which are more conducive to bearing positioning in use , Bearings of this size can only accept radial loads.Needle bearing (needle bearing) is a roller bearing with cylindrical rollers, relative to its diameter, the rollers are both thin and long.
Although the bearing has a small cross-section, the bearing still has a high load-accepting ability. At this time, the outer surface of the journal and the outer surface of the housing hole that match the bearing are directly used as the inner and outer rolling surfaces of the bearing to ensure the load capacity and running performance It is the same as the bearing with ferrules, except for the bearings listed in the catalog, which can be used for ordinary engineering bearings.
It is especially suitable for supporting structures where the size of the radial device is limited. The needle roller bearing is equipped with thin and long rollers (roller diameter D≤5mm, L/D≥2. Depending on the place of application, bearings without inner ring or needle roller and holder components can be selected. This kind of roller is called a needle roller.5, L is the roller length), so The radial structure is compact, and its inner diameter and load can be the same as other types of bearings.
