High strength copper alloy is sintered or cast on the surface of high-quality carbon steel plate as the substrate, and dispersed sintered or embedded with solid lubricant on its working surface according to the operating conditions. This manufacturing process achieves complete metallurgical bonding between copper and steel, which has stronger wear resistance and lubricity compared to traditional integral copper alloy products, lower cost, stronger stability of the bottom steel matrix, and longer overall service life. While reducing material costs, it also improves its load-bearing capacity.

Copper alloy embedded solid lubricant self-lubricating bearings combine the wear resistance of copper alloys with the self-lubricating properties of solid lubricants, making them maintenance free during use. The product is widely used in high load, intermittent or swinging motion, such as automobile and locomotive production lines, water turbines, reservoir work/accident doors, plastic machinery, punch peripheral equipment, etc. According to the operating conditions, various types of copper alloys can be provided.

The FZ steel ball cage is made of copper alloy, hard aluminum alloy or POM resin as the matrix, and has holes arranged in an orderly manner, of appropriate size and special shape machined on its outer circular surface. Insert rolling bearing steel balls into these holes and fix them using advanced groove circumference locking technology.

The metal composite self-lubricating material is made of high-quality low-carbon steel as the substrate, with a spherical porous copper powder layer sintered in the middle, and a wear-resistant lubricating material mainly made of PTFE tied on the surface as the bearing working layer. This material has excellent mechanical bearing capacity, and the middle copper powder layer can not only timely transfer the heat generated during the operation of the bearing, but also improve the bonding strength between the plastic layer and the substrate. PTFE design is suitable for completely dry friction state, and various materials have been developed based on lubrication conditions, friction coefficient, and durability requirements. The PTFE metal composite material of SF-1 can provide the best performance in the widest range of loads, speeds, and temperatures, with or without external lubrication.

SF-2 material is a three-layer composite self-lubricating material made of polytetrafluoroethylene modified polyoxymethylene plastic as the surface layer. It is a benign boundary lubricating material, making it particularly suitable for bearings, thrust pads, sliders, ball seats, and other friction parts that are not easily lubricated by fluid dynamics due to high load and low-speed rotational motion, swinging motion, and frequent opening and closing under load. SF-2 can fully utilize trace amounts of lubricating grease and can be maintained for a long time without refueling under boundary lubrication conditions. Under completely oil-free lubrication conditions, the friction performance and allowable PV value of SF-2 are relatively low, so oil storage pits are usually rolled out on the plastic surface and lithium based lubricating grease or silicone grease is applied during assembly.

The JF-800 bimetallic composite bearing is made of high-quality low-carbon steel as the substrate, and the surface is sintered with copper alloys (CuPb10Sn10, CuPb6Sn6Zn3, CuPb24Sn4, CuPb30, AlSn20Cu, CuSn8Ni) with low friction characteristics as the wear-resistant layer of the bearing. The copper alloy surface can be machined with various types of oil grooves, oil holes, oil cavities, etc. according to the needs of the operating conditions, to be suitable for situations where continuous or difficult refueling is not possible. The material can achieve good bonding strength and optimal load-bearing capacity through secondary sintering and secondary extrusion.

Copper coil bearings usually refer to thin-walled sliding bearings made of bronze or brass alloy strip as the substrate through precision rolling technology. This type of bearing has been widely used in the fields of industrial machinery, automotive manufacturing, and heavy equipment due to its unique structural design and excellent material properties.
