Technical Parameters

Modern designs are taking on a huge need for today's self-lubricating bearing materials. Even in extreme extreme operating conditions and maximum load conditions are also required maintenance-free. With the continuous improvement of cost requirements, the reliability of equipment and plant operation requirements are also getting higher and higher. Metal self-lubricating bearings are designed for maintenance-free and self-lubricating conditions under long-term service conditions, thus making it possible to design reliable long-term self-lubricating systems. Metal self-lubricating bearing materials can be widely used in high-load low-speed conditions of rotation, swing and linear reciprocating motion, but also applies to traditional lubrication can not be achieved or prohibited to use the occasion, or in special conditions such as dust, Load or irradiation conditions need long-term and stable use.

1. No oil supply device, hole injection, fuel tank processing
Cost of oil installations, processing fees, saving assembly fees, extra costs and time, and can significantly reduce manufacturing costs.
2. Lower operating costs
Significantly reduce the use of lubricants and equipment maintenance costs, while also eliminating the risk due to lack of oil supply caused.
3. Shorten design time
Non-oil can make the design and structure greatly simplified, reducing costs, saving design time. In addition, the use of self-lubricating bearings can also improve the mechanical properties, extend life and improve reliability, achieve significant results.
4. Oil recovery and environmental protection
No waste oil recycling, are environmentally friendly. JDB (500 # SP) self-lubricating bearing as machinery parts and components industry, there is some use in a broad sense. In order to make the mechanical drive is operating normally, a lot of effort. The bearing is divided into Rolling and plain bearings. General sliding bearings Under high load movement, foreign matter, the temperature condition, fuel, maintenance, etc. imperfect, it can cause nap. Under harsh conditions are generally plain bearings can not be used, solid mosaic self-lubricating metal shaft like this Order of the abrasion resistance of the nap, play bearing proper performance, to achieve the role of mechanical performance and maintenance-free maintenance.

1. Where possible, try to use standard design;
2. Please note that the surface of any foreign body assembly;
3. Sliding surface after use, because the solid lubricant film formation results in a surface with black or gray-black phenomenon, please do not scrub, as usual;
4. Before assembly, if the lubricating oil applied to the wear parts, can shorten the running-in period, in favor of mechanical operation, operation;
5. The assembly should be slowly pushed forbidden beat, so as not to damage bearings and cause deformation;
6. Design, should be used in different parts of the appropriate material, in order to improve the mechanical properties, extending bearing life;
7. In the high load, the reciprocating motion, it is recommended to use screws;
8. In fresh water, sea water, and at sea, the shaft, or recommend the use of stainless steel, chrome plated.

1. The flexible design, simple and convenient, using a wide range;
Oil supply system in the mechanical design is a lot of work, time-consuming device, the use of solid self-lubricating bearings need not be considered in the design of fuel means saving fuel plant equipment, and can for a variety of special occasions, the solid self-lubricating bearings designed into a variety of shapes to meet the needs of a variety of special occasions, the use of solid self-lubricating bearings, can significantly reduce the mechanical maintenance, fuel and other expenses.
2. No oil can be used;
Since the linear expansion coefficient greater than the solid lubricant from the metal substrate, so when solid self-lubricating bearings start running, the film will be transferred to the grinding member of the realized self-lubricating, so solid self-lubricating bearings can be difficult to use in refueling and can not refuel or fat place, even in the case of low-speed high-load, but also can play a good lubrication.
3. The use of low cost;
Traditional mechanical design, in a certain operating time, refueling and maintenance should always check the fuel gauge, oil installations is smooth, due to regularly refuel the body itself and cause pollution of the surrounding environment, resulting in increase of the maintenance costs and achieve after self-lubricating, not only can make the environment clean, but also greatly reduce the use of lubricant costs.
4. The high-load, low-speed conditions, can play a superior performance;
Solid self-lubricating bearings are used centrifugal casting high-strength brass alloy as a matrix, play a role in carrying the load, graphite has good self-lubricating properties of specially formulated as a lubricant, play a role in self-lubricating, it combines them the respective merits, even under high load, low speed conditions, can play a superior performance.
5. The reciprocating motion, rocking motion, and frequent start and stop the film formation difficult place to play excellent wear resistance;
The solid lubricant self-lubricating bearings are arranged principle is to ensure that all parts of the grinding member has a lubricant effect during operation of the thus arranged with the lubricant must be based on the direction of movement of the grinding member arranged to determine the position of the lubricant.
6. superior chemical resistance and corrosion resistance;
Solid self-lubricating bearing lubricant is specially formulated with graphite, PTFE, molybdenum disulfide and other wear-resistant material, which has a stable molecular structure, metal matrix can have different chemical resistance and corrosion resistance depending on the metal of selected, solid self-lubricating bearings and therefore has excellent chemical resistance and corrosion resistance.
7. The cost of the product more competitive, compared with similar products, long working life, required little maintenance, replacement replacement cycle is long, a good performance.
