Bronze-graphite bushing
Bronze-graphite self-lubricating sliding bushings Spherical bronze-graphite bushings are formed from a bronze alloy with porosity up to 20-25% volume. The oil contained in the porosity allows for permanent lubrication of the space between the bearing and the shaft. Application advantages: the presence of oil reduces the possibility of scuffing; allows the bronze-graphite sleeve to remain operational for thousands of hours without wear; there is no need for lubrication; produces little noise. The products are used in electrical equipment, household appliances, used in printing machines, machine tools, etc. To order: it is possible to produce products according to the customer’s specifications. It is possible to buy bronze-graphite bushings on the company’s website.

Product features
1、No need for oil supply device, oil injection hole, oil tank processing
The cost of oil supply device, processing fee, assembly fee and other extra costs and time savings can significantly reduce manufacturing costs.

2、Reduction of operation cost
Significantly reduce the amount of lubricating oil used and the maintenance cost of the equipment, in addition to eliminating the risk caused by insufficient oil supply.

3、Reduction of design time
In addition, the use of self-lubricating bearings can also improve mechanical performance, extend service life and improve reliability and other aspects to obtain significant results.

4、Lubricant recovery and environmental protection
No need for waste oil recycling treatment, which is conducive to environmental protection.
JDB (500#) self-lubricating Oil-free Bushing as mechanical industry parts, there is a certain broad sense of use. In order to make the mechanical transmission run properly, a lot of efforts have been made. The bearings are distinguished into rolling bearings and sliding bearings. The general sliding bearing Oil-free Bushing will cause hair pulling under high load movement method, foreign material mixing, temperature condition, oil supply, and imperfect maintenance. Like this general sliding Oil-free Bushing can not use the harsh conditions, solid inlay type metal self-lubricating Oil-free Bushing bearing wear resistance, hair pulling resistance on, play Oil-free Bushing bearing should be performance, to achieve high performance of machinery and maintenance-free role.

5、Use precautions
1、If possible, try to use standard specifications when designing.
2、Please pay attention to the presence of foreign matter on the surface when assembling.
3、After using the sliding surface, there is black or gray-black phenomenon on the surface due to the oil film formed by solid lubricant, please do not scrub, use as usual.
4、Before assembling, if the lubricant is applied to the wear parts, it can shorten the period of integration and facilitate the operation and running of the machine.
5、The assembly should be slowly pressed into, strictly forbidden to knock, so as not to damage the bearing and cause deformation.
6, the design, different parts should be selected with the appropriate material, in order to improve the mechanical properties, to extend the service life of Oil-free Bushing bearings.
7、In high load-bearing, reciprocating motion, it is recommended to use screws to fix.
8, in fresh water, seawater and in the sea operation, the grinding shaft is recommended to use stainless steel or surface chrome plating.

Advantages of solid self-lubricating Oil-free Bushing bearing
Oil supply system in the mechanical design is a labor-intensive, time-consuming device, the use of solid self-lubricating Oil-free Bushing bearing in the design does not need to consider the refueling device, saving the refueling device equipment, while for a variety of special occasions, the solid lubrication bearing design 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 Inspection and maintenance, oil and other costs.

2、No oil can be used.
Because the coefficient of linear expansion of solid self-lubricating lubricant is greater than the metal matrix, so when the solid self-lubricating Oil-free Bushing bearing starts to run, the oil film will be transferred to the wear parts and achieve self-lubrication, so the solid self-lubricating Oil-free Bushing bearing can be used in places where it is difficult to add oil and can not add oil or grease, even in the case of low speed and high load Even in the case of low speed and high load, it can play a good role in lubrication.

3, low cost of use.
Traditional mechanical design, in a certain operating time, to often refuel maintenance, check the oil table, oil supply device is smooth, due to regular refueling led to the body itself and the surrounding environment pollution, resulting in increased maintenance costs, the realization of self-lubrication, not only can achieve a neat environment, and greatly reduce the cost of using lubricants.

4. Superior performance under high load and low speed conditions.
Solid self-lubricating Oil-free Bushing bearing is made of centrifugal casting of high-strength alloy brass as the substrate, which plays the role of load-bearing, and a special formula of graphite with good self-lubricating properties as the lubricant, which plays the role of self-lubricating, so it integrates their respective advantages, even in the case of high load-bearing, low speed, can play a superior performance.

5, reciprocating motion, rocking motion, start and stop frequently and other places where oil film formation is difficult, can play a superior wear resistance.
The arrangement principle of solid self-lubricating Oil-free Bushing bearing lubricant is to ensure that the lubricant is available in all parts of the grinding parts during operation, therefore, the arrangement of lubricant must be determined according to the direction of movement of the grinding parts to determine the location of the lubricant arrangement.

6、Superior chemical resistance and corrosion resistance.
The lubricant of solid self-lubricating Oil-free Bushing bearing is made of special formula of graphite, PTFE, molybdenum disulfide and other wear-resistant materials, which has stable molecular structure, and the metal matrix can be selected according to different metals with different chemical resistance and corrosion resistance, so the solid self-lubricating Oil-free Bushing bearing has superior chemical resistance and corrosion resistance.

7, product cost is more competitive, compared with similar products, longer working life, requires little maintenance, long replacement cycle, good performance.
