What is a bearing bush?
What are bearing bush? Speaking of this name, most people are probably both unfamiliar and familiar. The familiarity lies in the fact that we may have heard of something called a bearing, and the strangeness lies in the fact that although there is only a word difference, we do not know much about the bearing. In fact, the function of bearings and bearings is similar, which is used in the machinery manufacturing industry and automobile maintenance industry to increase the mechanical rotation rate and reduce the friction generated during the rotation. Bearings can be divided into plain bearings and rolling bearings, of which plain bearings are approximately equal to bearings. It can be said that the bearing is one of the important components of the bearing, without the existence of the bearing, the use of the bearing will produce a certain resistance, which will adversely affect the entire use object. Therefore, we must have a preliminary understanding of the structure of the bearing, understand the purpose of the bearing and the precautions in the process of use, and lay a solid foundation for future daily application.
The basic construction of the bearing
Bearing bush, also known as "bushings", usually present a semi-cylindrical shingle surface. Because it resembles the tiles on the roof, hence the name. Most of the bearings on the market are alloys, which are composed of bronze, carbon graphite and other materials. Babbitt alloy has strong wear resistance, so most of the bearings made of babbitt alloy are durable, safe and reliable. Of course, in some special cases, bearings made of wood, rubber and other materials will also appear. The material of the bearing depends mainly on the occasion and use time of its application.
Precautions for bearings during use
Although the bearing is polished, very smooth, and made of a combination of high-temperature resistant materials, in the daily use process, if the sliding bearing is not well lubricated at high speed, friction between the bearing and the shaft is likely to occur. Once a large friction force is generated, the temperature of the component will rise rapidly, and when it reaches a certain level, it will burst out sparks and burn out the material. Therefore, in the usual use process, especially in the manufacturing process of automobile engines, good lubrication work should be carried out, and the friction between the bearing pad and the rotating shaft should be strictly controlled to prevent the temperature from being too high. In addition, bearings that are overloaded beyond their factory settings are likely to burn out. Therefore, we want to use it with caution and care.
SNW very much welcomes customers to call and email, or leave a message to consult, you can customize the bearing, bearing seat and customized processing metal parts and other products.
