EPEN EB65 Self-Lube Parts



EB65 Product Profile

Solid lubricated bearings are sliding blocks are self-lubricated bearings are obtained by means of drilling orderly arranged holes in proper size on the surface of metallic matrix of the bearings before filling the solid lubricant with self-lubrication capability (the area of the solid lubricant applied is usually 20% to 30% of the abrasion area). The bearings integrate the advantages of both the metallic matrix and the specially formulated Iubricants and break through the limitation of the ordinary bearings, which depends on the oil for lubrication.

The solid lubricant bearings are especially suitable for oil-free, high-temperature, high-load, low-speed,anti-fouling, anti-corrosion, anti-radioactivity circumstances as well as the special circumstances in water or vacuum settings where it is impossible to add oil for lubrication. This product is widely applied to the steel rolling equipment, filling equipment, water turbines, steam turbines, instruments and meters as well as mine machinery, vessel machinery, textile machinery, ship building industry, cosmonautics and navigation, etc. They can be used for general engineering machinery too. The base materials of solid lubricant bearings shall be determined according to the working conditions of the bearings.The commonly used materials high-strength copper, tin bronze and cast iron, etc. The filled solid lubricant is mainly graphite and addictive. Various additives are for various working conditions. Therefore, according to the working conditions of the bearings, a mix of metallic matrix and filled solid lubricant can enable the products to meet the specific requirements in various conditions with various temperatures, loads, movements and ambient substances and meanwhile, ensure stabilized and reliable functioning.

Features of The Solid Lubricant Bearings

1.Flexible design, simple, convenient with wide applications
The designing of oil-feeding system is both a labor consuming and time consuming job. Therefore, the neglecting of oil-feeding apparatus in the designing of solid lubricant bearings saves the cost of oil-feeding apparatus. Besides, for various specific circumstances, the solid lubricant bearings can be designed into various types to meet the requirements thereof. The use of solid lubricant bearings can greatly reduce the cost of mechanical maintenance and oil.

2. Functional in absence of oil
Since the linear expansibility of solid lubricant is greater than metallic matrix’s, when the movement of solid lubricant bearings(SLB)start, the lubricant is transferred onto the parts in abrasion thus realizing the self-lubrication. Therefore, the SLB can be used in circumstances where oiling and greasing is difficult or impossible and they perform excellent lubrication even under low-speed and high load circumstances.

3. Cost efficiency
The traditional mechanical designing requires frequent oiling maintenance; oil gauge check shall be performed to ensure the passage of oil supplying apparatus is clear. Since the periodical oiling can cause pollution to the machines themselves as well as to the ambient surroundings, resulting in an increase of the maintenance cost,the realization of self-lubrication can not only make the environment clean but greatly reduce the lubricating costs as well.

4. Excellent performance under high-load, low-speed circumstances
The SLBs are made of rotational cast high-strength copper as the matrix, which functions as load bearers.Besides, SLBs use specially formulated graphite as lubricant, ensuing excellent self-lubrication. Combining the advantages of both the matrix and lubricant, SLBs are capable of expert their wonderful performance in circumstances with high load and low speed.

5. In circumstances where it is difficult for the oil films to generate, such as the alternative movements, swinging movements and frequent on-and-off, SLB highlights their excellent resistance to abrasion. As the principle of the arrangement of SLB lubricant is to ensure that each part of the equipment is involved in the lubrication throughout the movement, the location of the lubricant shall be determined according to the movement direction of the parts in abrasion.

6. Excellent chemical resistance and corrosion resistance
The lubricant for SLB is formulated out of the abrasion-resistant materials such as graphite and PTEE and has stabilized molecular structure. The metallic matrix can be selected according to the various chemical resistance and corrosion resistance accordingly. Therefore, the SLB enjoys high chemical resistance and corrosion resistance.

7. The cost of the products is more competitive and compared with other products of the same kind, the SLB features in longer service hours, less maintenance, longer replacement period and better performance.
