Bronze graphite self - lubricating bearing
Bronze inlaid bearing is a solid lubrication product with CuSnZn6Pb3 bronze as the substrate and graphite and MoS2 as solid lubricants.Because the density of CuSnZn6Pb3 bronze is higher than that of high force brass, it is very wear-resistant in the case of high temperature and low load.At present, the product has been used in the fireplace door, oven raceway, rubber machinery, light industry machinery, machine tool industry and other low load, high temperature, medium speed occasions.

State distribution of graphite self - lubricated bearings
can be used for a long time without maintenance;
designed for high static load and dynamic load;
it has a very low and stable friction coefficient and no "adhesion" phenomenon;
dust resistance, corrosion resistance, impact resistance and edge load resistance;
the metal substrate has good shock-absorbing capacity;
can be used in a wide range of temperatures;
suitable for reciprocating, rotating and oscillating situations where startup is frequent
and oil film is difficult to form; very low wear rate, long service life.
The substrate of the VSB solid self - lubricating bearing shall be determined according to the working conditions of the bearing itself.More commonly used materials are colliers brass, tin bronze, cast iron, etc.The embedded solid lubricating materials are mainly graphite and additives. Different additives are suitable for different working conditions.According to the working conditions of the bearing itself, the combination of different metal substrates and embedded solid lubricants can ensure that the bearing can meet the special needs of various working conditions such as temperature, load, movement and medium, and ensure stable and reliable operation.
Characteristics of VSB solid self - lubricating bearings
1.The design is flexible, simple, convenient
wide range of use: oil supply system in the mechanical design is a piece of labor.Time-consuming, the use of solid lubrication bearings in the design does not need to consider the refueling device, fuel device saving.At the same time, for all kinds of special occasions, the solid lubrication bearings can be designed into a variety of shapes to meet the needs of various special occasions, the use of solid lubrication bearings, can greatly reduce mechanical maintenance, oil and other costs.
2. Oil-free 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. Low use 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 and low speed.Can play superior performance:
The solid lubricated bearing is made of centrifugal cast high strength brass as the substrate, which plays the role of bearing load.Self-lubricating, so it combines their advantages.Even in the case of high load, low speed can still play superior performance.
5, reciprocating motion
shaking motion, starting and stopping frequently and other places where the formation of oil film is difficult, can play superior wear resistance:
The arrangement principle of solid lubrication bearing lubricant is to ensure that there is a lubricant effect on each part of the grinding part in the process of operation, so the arrangement of lubricant must be determined according to the direction of movement of the grinding part.
6. Superior drug resistance and corrosion resistance;
The lubricant of solid lubricated bearing is made of wear-resisting materials such as graphite and PTEE with special formula, it has stable molecular structure, metal matrix can be selected according to different metals with different drug resistance and corrosion resistance, so the solid lubricated bearing has superior drug resistance and corrosion resistance.
7. The product cost is more competitive. Compared with similar products, the product has a long working life and requires little maintenance.
