What materials are commonly used to manufacture dynamic and static bearings?

Static pressure bearing is a type of sliding bearing that uses a pressure pump to forcefully inject pressure oil into the extremely fine gap between the bearing and the shaft. This is an important component of many machines, which requires a large amount of raw materials to manufacture. Mainly including: metals, porous metals, non metals, etc. Metal is a commonly used bearing alloy, bronze, aluminum based alloy, zinc based alloy, etc

Among them, the most commonly used alloy is bearing alloy, which is specially made for the design of bearings.

. The alias of bearing alloy is white alloy, which is mainly an alloy made of lead, tin, antimony or other metals. It has good wear resistance, which can prevent deformation or wear of the dynamic and static bearings during long-term use. The use of this type of alloy can effectively improve the service life of the dynamic and static bearings, and it also has good plasticity

Another issue is the use of metal materials. Generally speaking, plastic is more commonly used. Plastic bearings have good compressive strength and wear resistance, and can also be lubricated with oil and water, as well as self-lubricating properties. However, they also have the problem of poor thermal conductivity, which is a limitation of plastic.

. Therefore, it is generally not recommended to use dynamic and static bearings made of plastic in machinery that generates high heat. But it is still very suitable for children's toys, which is not only safe but also much cheaper in cost, making it a very affordable thing for businesses

It should be understood that dynamic and static pressure bearings are very precise small parts. If there is a slight deviation, they are generally not usable. Even if they are forcibly used, it is not good for the entire machinery. Good plasticity is more convenient for their processing and production.

. Its good thermal conductivity is also one of the reasons why it has become a raw material for dynamic and static pressure bearings. Parts like dynamic and static pressure bearings inevitably generate a certain amount of heat during operation. If the heat cannot be transferred out immediately, the loss of dynamic and static pressure bearings is still quite serious

Dynamic and static pressure bearings generally need lubricating oil because the oil has a strong adsorption capacity.

. Lubricating oil is used for the load-bearing capacity of the dynamic and static axes, which can effectively reduce the friction of the load-bearing capacity of the dynamic and static axes and improve the working efficiency of the dynamic and static pressure bearings. If the adsorption capacity of dynamic pressure bearings for oil is not strong, then once the lubricating fluid sticks to it, it is equivalent to wasting lubricating oil once. Therefore, hybrid bearings must have good oil absorption
