Bearing characteristics

Modern design is in great demand for today's self-lubricating bearing materials. Even in severe extreme operating environments and maximum load conditions require maintenance-free. With the continuous increase in cost requirements, companies are increasingly demanding the reliability of equipment and plant operations. Metal self-lubricating bearings can meet maintenance-free and self-lubrication under long-term use conditions, thereby making it possible to design reliable long-term self-lubricating systems. Metallic self-lubricating bearing materials can be widely used in rotating, oscillating and linear reciprocating motion under high-load and low-speed conditions. It can also be used in applications where conventional lubrication cannot be achieved or forbidden, or in special conditions such as dust and impact. It requires long-term and stable use under conditions such as load or irradiation.

Product Features

1. No need for oil supply device, oil hole, oil tank processing
The cost and time savings of the oil supply device, such as the cost, processing fee and assembly fee, can significantly reduce the manufacturing cost.
2. Reduced operating costs
Significantly reduce the use of lubricants and equipment maintenance costs, and also eliminate the risk due to insufficient oil supply.
3. Reduced design time
Oil-free can greatly simplify the design, structure, etc., reduce costs, save design time, in addition, the use of self-lubricating bearings can also improve the mechanical properties, extend the service life and improve reliability, etc. to obtain significant results.
4. Lubricant recovery and environmental protection
No waste oil recycling is required, which is conducive to environmental protection. JDB (500#SP) Self-lubricating bearings are used in a wide range of applications as part of the machinery industry. In order to make the mechanical transmission run normally, a lot of effort was put into it. The bearings are divided into rolling bearings and plain bearings. General sliding bearings can cause naps in high load motions, foreign matter mixing, temperature conditions, oil supply, and imperfect maintenance. Under the harsh conditions in which ordinary plain bearings cannot be used, the solid-inlaid type metal self-lubricating bearings are used to achieve the performance required for bearings in terms of wear resistance and pull resistance, and to achieve high-performance of the machine and maintenance-free maintenance.

Use caution

1. Where possible, use standard specifications as much as possible during design;
2. Please pay attention to the presence of foreign matter on the surface during assembly.
3．After using the sliding surface, the oil film formed by the solid lubricant causes the surface to have a black or grayish black phenomenon. Please do not scrub it and use it as usual.
4．Before assembly, if the lubricating oil is applied to the grinding parts, it can shorten the walking period, which is conducive to mechanical operation and operation;
5．Assembly should be slowly pressed into, is strictly prohibited, so as not to damage the bearing and cause deformation;
6．When designing, appropriate materials should be selected for different parts in order to improve the mechanical properties and extend the service life of the bearings;
7．In high load, reciprocating motion, screw fixation is recommended;
8．When working in fresh water, seawater and offshore, stainless steel or chrome plating is recommended for grinding shafts.

product advantages

1. The design is flexible, simple, convenient and uses a wide range;
The oil supply system is a laborious and time-consuming device in mechanical design. The use of solid self-lubricating bearings does not need to consider refueling devices during design. It saves oil refueling device equipment, and can also be used as a solid self-lubricating bearing for various special occasions. Designed in a variety of shapes to meet the needs of a variety of special occasions, the use of solid self-lubricating bearings, can greatly reduce the cost of mechanical maintenance, oil and other expenses.
2. No oil can be used;
Since the linear self-lubricated expansion coefficient of the solid self-lubricant is greater than that of the metal matrix, when the solid self-lubricating bearing starts to operate, the oil film will be transferred to the abrading piece to achieve self-lubrication, so the solid self-lubricating bearing can be used in difficult to refuel and can not be refueled or Where grease is present, it can provide good lubrication even at low speeds and high loads.
3. Low cost of use;
The traditional mechanical design requires frequent maintenance during certain operating hours. Check the oil meter and the oil supply device for unimpeded circulation. Due to periodic fueling, the body itself and the surrounding environment are polluted, resulting in increased maintenance costs and self-lubrication. Not only can we achieve a clean environment, but also greatly reduce the cost of using lubricants.
4. Excellent performance under high load and low speed conditions;
Solid self-lubricating bearings are made of centrifugally cast high-strength alloy brass as the matrix, which plays a role in carrying the load. With a special formula of graphite with good self-lubricating properties as a lubricant, it plays a role of self-lubricating, so it integrates them. The respective advantages can exert superior performance even under high load and low speed conditions.
5. It can exhibit excellent wear resistance in places where oil film formation is difficult, such as reciprocating motion, rocking motion, and starting and stopping.
The principle of the arrangement of the solid self-lubricating bearing lubricant is to ensure that all parts of the abrading parts have lubricant during operation. Therefore, when arranging the lubricant, the position of the lubricant must be determined according to the direction of movement of the abrading parts.
6. Excellent chemical resistance and corrosion resistance;
The lubricant of solid self-lubricating bearings is made of specially formulated graphite, PTFE, molybdenum disulfide and other wear-resistant materials. It has a stable molecular structure. The metal matrix can have different chemical resistance and corrosion resistance according to different metals. Sex to choose, so solid self-lubricating bearings have superior chemical resistance and corrosion resistance.
7. The product cost is more competitive. Compared with similar products, the service life is longer, and less maintenance is required. The replacement replacement cycle is long and the performance is good.
