Self-lubricating bearing industry overview

rewrite below With the development trend in the field of self-lubricating bearings, the production process and raw materials of self-lubricating bearings keep pace with The Times, and the types of commodities are gradually rich and colorful. According to the difference of product structure and production and manufacturing raw materials, self-lubricating bearings are divided into three categories: laminated, single-sided and other categories, which are divided into several subcategories.The actual results are shown below:

“Laminated” self-lubricating bearing products are made of two or two kinds of different kinds of rolling bearing raw materials stacked composite, in which the lining raw materials have the effect of self-lubricating bearing, the plate has the effect of supporting point, and other raw materials have the effect of connecting and connecting. The actual wetting effect of the “multilayer” commodity is of high quality, and its bearing capacity is determined by the tensile strength of the surface material.According to the type of sheet material and lining material, it can be divided into metal material sheet and metal material lining layer, metal material sheet and non-metal material lining layer and non-metal material sheet and non-metal material lining layer.

“Single type” self-lubricating bearing products is made from a variety of rolling bearing raw materials, Viiplus authorized dealer of goods with the aid of rolling bearing with self-lubricating bearing raw material in the raw materials such as high purity graphite, molybdenum disulfide, ptfe, lead etc. In order to develop RunHua, according to the type of rolling bearing raw materials, can be divided into metal materials and nonmetal materials. Non-metallic material single-sided self-lubricating bearings include the overall non-metallic material rolling bearings, non-metallic material production rolling bearings, etc. Metal material single-sided rolling bearings include solid – state embedded products and oil – containing products.” Solid embedding type” self-lubricating bearings are produced and processed in advance on the metal material sheet according to a certain ordering method, and then solid lubricants are placed in them; In the whole process of work, because of the effect of friction heat or working temperature, solid lubricant is slightly prominent on the rolling surface, and according to the friction, transfer film is produced on the metal material sheet and layer transfer surface, thus having the effect of reducing wear and abrasion. “Oil content type” self-lubricating bearing is the metal powder according to the powder non-metallurgical processing technology to inhibit the calcination into a porous structure of raw materials, and then fill the porosity with grease; In the whole process of work, due to the effect of friction heat or working temperature, the grease is precipitated from the rolling bearing, and the grease film is produced on the metal material sheet and layer transfer surface, thus having the effect of reducing wear and abrasion.

As the field of self-lubricating bearings evolves, production processes and raw materials are continuously updated to meet modern demands, leading to a diverse range of products. Self-lubricating bearings are categorized into three main types based on their structure and materials: laminated, single-layer, and other specific types, each with its own subcategories.

Laminated self-lubricating bearings consist of two or more layers of different bearing materials. The inner lining material provides self-lubrication, the outer plate serves as a support, and additional materials are used for connectivity. These multilayer bearings offer excellent lubrication quality and their load capacity depends on the tensile strength of the top layer. Depending on the materials used, these can be further divided into combinations such as metal plate with metal lining, metal plate with non-metal lining, and non-metal plate with non-metal lining.

Single-layer self-lubricating bearings are composed of various bearing materials including high purity graphite, molybdenum disulfide, PTFE, and lead, among others. These bearings are categorized based on the material type into metal and non-metal varieties. Non-metal single-layer bearings include entirely non-metallic bearings and those manufactured from non-metallic materials. Metal single-layer bearings are available as solid embedded products and oil-impregnated products. Solid embedded bearings are made by machining slots into metal plates and inserting solid lubricants. During operation, the solid lubricant forms a transfer film on the metal surface due to friction, reducing wear and tear. Oil-impregnated bearings are created using powder metallurgy to form a porous structure filled with grease, which, when heated by friction, exudes to form a lubricating film, thus reducing wear.
