Bearing Development 


1. Development of bearing products


Bearing is the bearing shaft parts, known as the "mechanical joint", is an indispensable part of modern mechanical equipment.The main function of the bearing is to support the rotating shaft or other moving body, guide the rotational movement or movement and bear the load transmitted by the shaft or the parts on the shaft.


The modern industrial bearing industry arose from the late 19th century to the early 20th century.Since the 1950s, with the rapid development of high and new technologies such as aerospace, nuclear energy industry, electronic computers, optical and electromagnetic instruments, precision machinery and so on, the world bearing industry has entered a period of comprehensive innovation, with rapid development of manufacturing technology, and increasingly mature varieties, bearing precision, performance and life.


2. Classification of bearing products


There are many types of bearing products, according to the different structure and working principle, can be divided into "rolling bearing" and "sliding bearing" two categories.The rolling bearing refers to the bearing that contains the rolling body for rolling motion between the parts. The sliding bearing is the bearing that does not use the rolling body and only works under the sliding friction.


The rolling bearing has the advantages of small friction coefficient, high transmission efficiency and good mechanical properties.Rolling bearings have been standardized, serialized and generalized, suitable for mass production and supply, promoting the overall development of the bearing industry.


Sliding bearing has the advantages of small volume, high bearing capacity, little vibration, little noise and more structural changes.Therefore, the sliding bearing has obvious advantages over the rolling bearing in the occasions with large load bearing, compact structure and impact load.The advantages of the variable structure of sliding bearing also enable it to be applied to various mechanical parts of different shapes.


According to the different lubricating materials and lubricating ways, the sliding bearings can be further divided into "self-lubricating bearings" and "general sliding bearings".Traditional sliding bearings need to add lubricating oil, grease and other lubricating materials before or during the work process, so as to form a fluid or semi-fluid film on the friction interface and play an effective role of lubrication, known as "general sliding bearings".Such as thick - wall bearing, thin - wall bearing, etc., belong to the general sliding bearing.Self-lubricating bearing is a new type of sliding bearing products, this kind of products use self-lubricating material as a lubricant or pre-filled with lubricant sealed up, can be used for a long time, work process without adding lubricant.Among them, the bearings made of solid self-lubricating materials as lubricants are also known as "oil-free bearings" because they do not need to add oil, grease and other traditional lubricants.At present, the main raw materials used for making self-lubricating bearings in the world are copper, steel and other metal materials and non-metal materials, such as polymer products (), graphite.

3. Development of self - lubricating bearings


  The manufacture of self - lubricating bearings originated in England.In the 1950s, (polytetrafluoroethylene) began to be tested as a bearing material in the UK, and the sintering process of copper powder also got a breakthrough.In 1956, the world's first self-lubricating  bearing with as lining and steel plate as support was put on the market.In the late 1960s, self - lubricating bearings began to enter the aerospace and other cutting-edge technology applications.Since the 1970s, British self-lubricating bearing manufacturers have licensed the technology to French, German, Japanese and American companies, which promoted the rapid development of the world's self-lubricating bearing industry. Self-lubricating bearings have gradually entered all mechanical manufacturing fields.


4. Classification of self - lubricating bearing products


  With the development of the self-lubricating bearing industry, the production technology and materials of self-lubricating bearing are constantly innovated, and the types of products are gradually enriched.According to the different product structure and manufacturing materials, the self-lubricating bearings are divided into laminated class, single-layer class and other three categories, which are divided into several subcategories.The details are as follows:


self lubricating bronze bushing







































"Multilayer type" self-lubricating bearing products are composed of two or more different types of bearing materials, in which the liner material plays the role of self-lubrication, the substrate plays the role of support, and other materials play the role of connection and transition.The lubricating effect of "laminated" product is good, and its bearing capacity is determined by the compressive strength of the surface material.According to the types of substrate and lining materials, it can be divided into metal substrate and metal lining layer cladding, metal substrate and non-metal lining layer cladding, and non-metal substrate and non-metal lining layer cladding.


"Single layer type" self-lubricating bearing products are made of a type of bearing materials, products rely on the bearing materials contained in the self-lubricating materials such as graphite, molybdenum disulphide, polytetrafluoroethylene, lead and so on to lubricate, according to the type of bearing materials, can be divided into metal class and non-metal class.Non - metallic single - layer self - lubricating bearings mainly include integral non - metallic bearings, non - metallic rolling bearings.Metal class single - layer bearings mainly include solid - inlaid products and oil - bearing products."Solid inlaid" self-lubricating bearings are pre-processed with holes or grooves on the metal substrate in a certain arrangement, and then solid lubricant is embedded in them.In the working process, due to the action of friction heat or ambient temperature, the solid lubricant is slightly prominent on the sliding surface, and forms a transfer film on the metal substrate and dual surface through friction, thus playing the role of friction reduction and wear resistance."Oil-bearing" self-lubricating bearing is a porous material made of metal powder pressed and sintered by powder metallurgy process and then filled with lubricating oil in the pores.Due to the action of friction heat or ambient temperature, the lubricating oil precipitates out from the bearing and forms a lubricating film on the metal substrate and dual surface, thus playing the role of friction reduction and wear resistance.


5.Characteristics of self - lubricating bearing products


Self-lubricating bearings are suitable for places where refueling is impossible or difficult.Due to the special requirements of production process, automobile manufacturing, machinery industrial enterprise of some of the key equipment to run under extreme conditions, because of the large heavy equipment, high temperature, dust or acidic corrosion factors such as gas in the air, it is difficult to add lubricating oil for the equipment, so the rolling bearing or general sliding bearing friction and wear, easy to have the bearing bite or bite dead, cause parts wear and damage, lead to equipment shutdown.In order to produce continuous operation, in addition to the original design requires the installation of a number of equipment wheel repair, but also a large number of maintenance personnel, spare parts and energy consumption.Therefore, automobile manufacturing, engineering machinery, mold industry and other enterprises have the demand for special lubricating materials under complex working conditions.Oil-free can greatly simplify the bearing design and structure, reduce the cost and save the design time. It can use the bearing without maintenance or less maintenance, and also avoid the risk caused by insufficient oil supply.Through the research of self-lubricating bearing composite materials and self-lubricating bearing, the publisher has achieved innovative breakthrough in the material formulation and preparation process, which can solve the lubrication problem under special working conditions for customers.


Since the self-lubricating bearing does not need oil supply device, no oil can be added in the working process, so it can save a lot of installation and operation costs, improve mechanical performance, improve service life and reliability.Oil-free treatment does not require waste oil recovery and is also beneficial to environmental protection.The hardness requirement of self - lubricated bearing for grinding shaft is low, which reduces the processing difficulty of related parts.Self-lubricating composite bearing structure, the surface can be electroplated a variety of metals, can be used in corrosive medium.In addition, since no oil lubrication does not exist grease volatilization problem, self-lubricating bearings can be used in high temperature and high pressure environment.


The performance comparison between the self-lubricating bearing and the general bearing is as follows:
