The bearing is one of the important parts in the rotating machine. It should be made in high durability, precision, and reliability. The bearing needs to be able to maintain the high-speed rotation of the machine. The bearing is used for carrying the heavy loads efficiently. It has been used for several applications of the machine such as airplane, automobile, construction equipment, refrigerators and ceiling fans. There are several materials that can be used for making bearing such as chrome steels, stainless steel, and plastic. Each material has its own functions and advantages. For example, the bearing that is made from the chrome steels can be used for the inner ring, outer ring, balls, and rollers. The chrome steel is made from the mixture of high carbon and 1.5 chromium content. On the other hand, the bearing that is made from stainless steel is more resistant to the corrosion process. The high level of corrosion resistance is caused by the high concentration of chromium that is about 18% and the addition of the nickel. The mechanism of the corrosion-resistant is the forming of chromium oxide from the reaction of chromium and oxygen. The chromium oxide will form a passive layer that can be used as the bearer of the corrosion process. The bearing also can be made from plastic such as molded nylon plastic and molded acetal.
As mentioned previously that bearing is important for the machine. There are several types of bearing that are usually used in the machine such as ball, cylindrical and needle, tapered roller, and spherical roller. Each type can be used for a specific function and has its own characteristics. The ball bearing has the characteristic such as ball as the main provider for the roller function. It has some specific characteristics such as high speed, can be used for light to medium loading, and low friction. This type of bearing mainly used for light machine applications. Well, the people will often find this type of bearing in several machines such as fan, wheel bearing, rollerblades, and others. On the other hand, the cylindrical and needle bearing can be found in several machines such as gearboxes and transmission and construction equipment. It has some specific characteristics such as low friction and can be used for medium-heavy loading. Meanwhile, the tapered roller is found in the power generation machine. It has a specific characteristic such as medium friction and can be used for medium-heavy loads applications. The spherical roller bearing can be found on the conveyor, pulp and paper machine.
Well, the bearing in the ball shape is commonly used in industrial applications such as agricultural applications, electric motors, hand tools, construction equipment, iron industry, steel industry, and wood processing. If people want to purchase the bearing, they can contact some company that mostly worked on providing bearing and other parts. They can choose the bearing based on its material, shape, and function. Understanding the specific functions and advantages of each bearing will help the people to get their needs.
