In our production life, tungsten ball bearings have a lot of important influence on us. So what are tungsten ball bearings and what advantages do they have over ordinary bearings? Let's take a look.
The following is a list of contents:
l Characteristics of tungsten ball bearings
l Structural composition of tungsten ball bearings
l Applications of tungsten ball bearings
A tungsten ball bearing is a kind of rolling bearing, the tungsten sphere is installed in the middle of the inner and outer steel ring, which can bear a large load, also called a ball bearing. Tungsten ball bearing has good wear resistance, it’s even long time work, there is not much scratch or split, so it can accept higher intensity work or work a long time.
Meanwhile, compared with other alloy materials, tungsten alloy is easier to process, so the processing cost will be relatively lower. In addition to the several advantages mentioned above, tungsten ball bearings also have the characteristics of higher melting temperature, better corrosion resistance, stronger impact resistance, higher elastic modulus, and extremely superior shielding effect on rays.
Tungsten ball bearings are mainly composed of four basic components: tungsten alloy ball, inner ring, outer ring, and cage or retainer (also called cage). The balls and rings are usually made of high chrome steel, and the Rockwell C-scale hardness is about 61-65. The hardness of the retainer is lower than that of the ball and ring, and its material is either metal (e.g. medium carbon steel, aluminum alloy) or non-metal (e.g. Teflon, PTEF, polymer material). In contrast, tungsten ball bearings have a much higher overall material hardness and are more wear and heat resistant.
The purpose of tungsten ball bearings is to determine the relative position of two parts (usually the shaft and the housing) and to ensure their free rotation while transmitting the load between them. At high speeds (e.g. in gyroscopic ball bearings), this use can be extended to include free rotation with virtually no wear in the bearing. To achieve this state, an adhesive fluid film called an elastomeric hydrodynamic lubrication film may be used to separate the two parts of the bearing. Tungsten ball bearings are mainly used in various machines and equipment with rotary parts.
And the use of bearings in machines including automobiles, aircraft, generators, etc. Bearings are also used in household appliances, such as refrigerators, vacuum cleaners, air conditioners, etc. In these machines, bearings are responsible for supporting the "shaft" with wheels, gears, turbines, rotors, and other parts, and helping the shaft to rotate smoothly. Because of the many rotating "shafts" used in various machines, bearings have become an essential component and are called the "food of the machinery industry". Machines that use tungsten ball bearings instead of conventional bearings can make the parts where the tungsten ball bearings are located last longer.
