Metal Mosaic solid self-lubricating bearing (JDB) is a kind of both metal bearing characteristics and self-lubricating bearing characteristics of novel lubricated bearing, by colliers brass metal substrates such as load bearing, special lubrication formula of solid lubricating materials. In the process of friction metal base material for most of the load. By friction, hole or groove of solid lubricant to the friction surface transfer or negative transfer, the friction surface to form a good lubrication, strong adhesion and uniform coverage of solid transfer film, greatly reduce the friction and wear. With the friction, the embedded solid lubricant provided on the friction surface, to ensure the long-term operation of the friction pair when good lubrication. It breaks the boundaries of generally depends on the oil film bearing lubrication. With high bearing capacity, impact resistance, high temperature resistant, low friction coefficient, wear small, no noise, self lubricating the advantage such as being strong of performance, but also for shaft without wear and tear, there will be no card shaft use, etc. Especially suitable for the overload, low speed, reciprocating or swing, difficult to lubrication and oil film formation, not afraid of the water and other acid erosion and erosion. Users generally reflect not only fuel-efficient inlaid bearing, energy conservation, and its working life is longer than ordinary sliding FAG 6203 Bearings Of China

Solid lubrication bearing (JDB) at least has the following advantages:
1, design flexible, simple and convenient, wide range of use:
Fuel supply system in the engineering design is a piece of work, time-consuming setup, using solid lubrication bearings do not need to consider when designing refueling device, save the refueling devices, as well as for a wide variety of special occasions, the solid lubricated bearing design into various shapes, in order to satisfy various occasions, the use of solid lubrication bearing, can greatly reduce the mechanical maintenance, oil and other expenses.
2, no oil can be used:
Due to the linear expansion coefficient of solid lubricant is greater than the metal matrix, so when the solid lubricated bearing, when we started running on the oil film will shift to a grinding and realize self-lubrication, so solid lubrication bearings can be used in the place where is hard to go and can't go or grease, even in the case of low speed and high load, also can have good lubrication effect.
3, using low cost:
The traditional mechanical design, in a certain operating time, want to often come on maintenance, check the oil, the oil supply device was clear, the body itself and the surrounding environment pollution caused by regular gas, result in an increase in maintenance costs, realize self-lubrication, not only can realize the environment clean and tidy, and greatly reduce the cost of the use of lubricating oil.
4, high load, low speed, can produce superior performance:
Solid lubrication bearing is centrifugal casting of high strength brass substrate, have the effect of bearing load, with special formula with good lubricating graphite lubricant, self lubricating effect, so it combines the advantages of their own, even in the case of high load, low speed, can produce superior performance.
5, reciprocating motion, swing motion, start stop frequent oil film forming difficult place, can play the superior wear resistance:
The arrangement principle of solid lubrication bearing lubricant is guarantee for grinding parts in the process of running parts have lubricant effect, therefore arranged lubricant must be according to the movement direction of the grinding parts to determine the arrangement of lubricant.
6, superior drug resistance and corrosion resistance:
Graphite solid lubrication bearing lubricant is a special recipe, PTEE and other wear-resistant materials, it has a stable molecular structure, the metal substrate can be according to the different metals have different drug resistance and corrosion resistance to choose, so solid lubrication bearing is superior drug resistance and corrosion resistance.
7, working life is longer, need very little maintenance, replacement replacement cycle is long, good performance.
Due to the special requirements of production process, industrial and mining enterprises of certain key equipment running in very bad condition. Due to the heavy equipment, high temperature, dust or air containing acid corrosion in gas CO, SO2, etc., bring many problems of equipment lubrication, friction and wear serious, in order to produce continuous operation, in addition to multiple devices in the original design required round outside, still must invest a lot of maintenance personnel. Seriously restricts the productivity, spare parts and the energy consumption greatly, has become the important obstacle of developing production. To this, the development and application of inlay type of self-lubricating bearings for the enterprise can solve the problem of lubrication under special working conditions, has brought obvious economic and social benefits
