Metallographic picture

Modern design is changing the demand for self-lubricating bearing materials. Maintenance is also required in severe extreme operating conditions and maximum load conditions. As requirements continue to increase, companies have high reliability requirements for equipment and plant operations. Metal self-lubricating bearings can be used for maintenance-free and self-lubricating under long-term use conditions. Bearing materials can be widely used for rotating, oscillating and linear reciprocating motion under high load and low speed conditions, and also suitable for traditional lubrication. It is forbidden to use.

Product specialty

1. The cost of the oil supply device, the processing fee, and the like can be greatly reduced.
2. Operating costs are reduced by the amount of lubricant used and equipment maintenance costs, and some risks are eliminated.
3. Shorter design times reduce costs, and the use of self-lubricating bearings improves mechanical performance and extends service life.。
4. Recycling and environmental protection of lubricating oil No waste oil recycling is required, which is conducive to environmental protection. CHB-JDB (500#SP) Self-lubricating bearings are used in the machinery industry and are used in a broad sense. In order to make the mechanical transmission work normally, a lot of effort has been made. The bearings are divided into rolling bearings and plain bearings. Under the severe conditions that the general sliding bearing cannot be used, the wear resistance and the fluff resistance of the solid inlaid metal self-lubricating bearing play the role of the bearing, and the performance of the machine is improved and maintenance-free.

Precautions for use

1. Where possible, standard specifications should be used when designing;
2. Please pay attention to the presence or absence of foreign matter on the surface during assembly;
3. After the use of the sliding surface, the surface is black or grayish black, please do not scrub, use as usual;
4. Before the assembly, if the lubricating oil is applied to the grinding parts, the running time can be shortened;
5. When assembling, it should be pressed in slowly, and it is forbidden to knock, so as not to damage the bearing.
6. When designing, different parts should be selected with appropriate materials to improve performance and extend the service life of the bearings;
7. In high load, reciprocating motion, it is recommended to use screw fixing；
8．8. Stainless steel or chrome plating is recommended for the grinding shaft when working in fresh water, sea water or at sea.

Product advantages

1. Design is flexible, simple, convenient and has a wide range of use；
The oil supply system is a labor-intensive, time-consuming device. The use of solid self-lubricating bearings does not require consideration of the fueling device during the design, which saves the fueling device and can be used for various special occasions. Bearings can greatly reduce the cost of mechanical maintenance, oil and other materials.
2. Can be used without oil；
Because the linear expansion coefficient of solid self-lubricants is greater than that of the metal substrate, when the solid self-lubricating bearings start to run, the oil film will transfer to the abrasive parts to achieve self-lubrication. It can also play a good role in lubrication.
3. Low cost of use;
The traditional mechanical design requires frequent refueling and maintenance during the operating time, checking the oil meter and whether the oil supply device is unblocked, which can greatly reduce the cost of using lubricants.
4. Excellent performance under high load and low speed conditions;；
Solid self-lubricating bearings use centrifugally cast high-strength alloy brass as the base, which plays the role of bearing loads, combining their respective advantages, and can exert superior performance even under high load and low speed conditions.
5. Reciprocating motion, rocking motion, frequent starting and stopping places where oil film formation is difficult, can exert superior abrasion resistance
The arrangement principle of solid self-lubricating bearing lubricants is to ensure that the abrasive parts have a lubricant effect during the running process. When arranging the lubricants, the arrangement position of the lubricants must be determined.
6. Excellent chemical resistance and corrosion resistance;
The lubricant of solid self-lubricating bearings is made of wear-resistant materials such as graphite, PTFE, molybdenum disulfide, etc., and has a stable molecular structure. Therefore, solid self-lubricating bearings have excellent chemical resistance and corrosion resistance
7. The product cost is more competitive, the working life is longer, and the performance is good.
