Self-lubricating bearings are commonly used and well known by customers, so who knows about this material? Let's letMingyang technologyXiaobian explains it for everyone!

Solid lubricant refers to the use of solid powder, film or some integral materials to reduce the friction and wear between two bearing surfaces. In the process of solid lubrication, solid lubricating materials and surrounding media should react physically and chemically with the friction surface to form a solid lubricating film to reduce friction and wear. Solid lubricating materials are divided into organic polymer materials and inorganic materials. Organic polymer materials include polytetrafluoroethylene, high density polyethylene, polyoxymethylene, polycarbonate, polyamide, polysulfone, polyimide, chlorinated polyether, polyphenylene sulfide and polyethylene terephthalate, etc. Inorganic materials include graphite, molybdenum disulfide, graphite fluoride, copper, gold and so on.

Solid lubricating materials have the following advantages under friction conditions:

1.The solid lubricant with the function of protecting the surface should have good film forming ability, and can form a strong chemical adsorption film or physical adsorption film with the friction surface, and adhere to the surface to prevent serious fusion welding or mutual transfer of metals between relatively moving surfaces.

2.Solid lubricants with low shear strength have low shear strength, so that the friction coefficient of friction pair is small, the power loss is low and the temperature rise is small. Moreover, its shear strength should not change in a wide temperature range, so that its application field is wide.

3.Good stability, including physical thermal stability, chemical thermal stability and aging stability, does not produce corrosion and other harmful effects. Physical thermal stability means that without the participation of active substances, temperature change will not cause phase transition or various changes in crystal lattice, so it will not cause changes in shear strength and lead to changes in friction properties of solids.

4.Chemical thermal stability means that the change of temperature in various active media will not cause strong chemical reaction. Physical and chemical thermal stability of solid lubricants is required, considering that high temperature, ultra-low temperature and performance will not change too much when used in chemical media, while aging stability means that solid lubricants are required not to deteriorate after long-term storage for long-term use. In addition, it is required to be non-corrosive to bearings and related parts, non-toxic to people and animals, and non-polluting to the environment.

However, there are many limitations in the re-friction condition of parts made of single material, and most of them are made of the above-mentioned material mixture, among which the backing type solid self-lubricating materials are most widely used.
