The so-called non-oil means less fuel without refueling, the goal of our research is to ensure that bearing this condition also showed a good performance and extend its life as much as possible. Self-lubricating bearings basic principle is that the solid lubricant in the initial operational phase of the bearing surface due to mutual friction asked to form a transfer film and covered with a wear member to the final formation of the solid lubricant film in order to achieve the purpose of self-lubricating, it cut off direct contact between the workpiece and thus well protected against wear member and workpiece extending bearing life.

high-strength copper alloy as base material, according to the use conditions by a certain percentage of its working surface machined hole and fill one solid lubricant. High-strength copper alloy provides a high load carrying capacity and the solid lubricant can be formed of a low friction. Under dry conditions we have designed a layer of film on pre-lubricated bearing surface ensures the shortest possible time will be transferred to the solid lubricant on the coupling member and form a valid solid lubricant film.

Modern design for today's self-lubricating bearing material is undergoing tremendous demand. Even in the severe operating environment and maximum extreme load conditions also require maintenance. As the cost of the increasing demand, business equipment and plant operation reliability requirements are also increasing. Metal self-lubricating bearings to meet the long-term maintenance-free and under the conditions of use of self-lubricating, thus making the design of reliable long-term self-lubricating system possible. Metal type self-lubricating bearing material can be widely used in high-load low speed rotation conditions, swivel and linear reciprocating motion, but also for conventional lubrication can not be achieved or prohibit the use of the occasion, or in special conditions such as dust, shock load or irradiation conditions require long-term and stable use.

1．No oil supply device, hole injection, the cost of processing oil sump means, processing fees, fees, extra assembly cost and time savings, can significantly reduce manufacturing costs. 
2. Reduce operating costs significantly reduce the use of lubricants and equipment maintenance costs, while also eliminating the risk caused due to insufficient supply. 
3. Shorten the design time can make oil-free design, greatly simplifying the structure, reducing costs, saving design time. In addition, the use of self-lubricating bearings can also improve the mechanical properties, extend life and improve reliability and so achieve significant results. 
4. Oil recovery and environmental protection No waste oil recycling, are environmentally friendly.
JDB(500#SP) Self-lubricating bearings 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, can cause nap. Under severe conditions such as general sliding bearings can not be used, solid metal mosaic self-lubricating bearings wear resistance, galling resistance, the bearing play its due 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 resulting in black or gray-black surface phenomenon, do not scrub, as usual;
4．Before assembly, if the lubricating oil applied to the wear member can shorten the walk-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, recommend using stainless steel or chrome plated.
