Sintered CuPb10Sn polymer plain bearings are an excellent choice for use in both agriculture and construction industries due to their unique combination of properties. These bearings are made from a sintered material that combines the strength and durability of copper with the lubrication and wear resistance of (polytetrafluoroethylene).
In agriculture, sintered CuPb10Sn bearings are often used in machinery and equipment that require smooth and reliable operation. Their self-lubricating properties help reduce friction and wear, improving the efficiency and lifespan of agricultural machinery. Wh it's tractors, harvesters, or irrigation systems, these bearings can handle the demands of heavy-duty agricultural work.
In the construction industry, sintered CuPb10Sn bearings are also widely used. They are often found in equipment such as excavators, loaders, and cranes, where high loads and frequent motion are common. The bearings' ability to withstand these conditions while maintaining smooth operation is crucial for ensuring the safety and efficiency of construction operations.
The CuPb10Sn alloy in these bearings provides excellent strength and wear resistance, while the component ensures smooth operation and reduced friction. This combination allows the bearings to perform well in both wet and dry conditions, making them suitable for a wide range of applications in both agriculture and construction.
Overall, sintered CuPb10Sn polymer plain bearings are a reliable and efficient choice for use in agriculture and construction machinery. Their unique properties help improve the performance and lifespan of equipment, reducing maintenance costs and downtime.
The oil-free bearing is a sliding bearing made of steel plate, sintered spherical bronze powder in the middle, and a mixture of and lead rolled on the surface.It has the characteristics of small friction coefficient, wear resistance, corrosion resistance, no oil lubrication.The use of this product can reduce the cost, reduce the size of the machine, avoid the phenomenon of biting the shaft and reduce the mechanical noise and other advantages.Composite self-lubricating bearings also have some disadvantages, such as poor wear resistance and poor thermal conductivity compared with traditional bronze self-lubricating bearings.

It is a polymer made of tetrafluoroethylene as monomer.White waxy, translucent, good heat and cold resistance, can be used in -180 ~ 260 C for a long time.This material has the characteristics of anti - acid, anti - alkali, anti - various organic solvents, almost insoluble in all solvents.At the same time, has the characteristics of high temperature resistance, its coefficient of friction is very low, so it can be used for lubrication, but also become easy to clean the ideal coating of the inner layer of the water pipe;Toxic, human carcinogen.

CuPb10Sn + Steel + self - lubricating oil - free bearing bearing of the molding processIs to take the rolling process, the disadvantage of the rolling process is the general accuracy, rolling process of production process efficiency is high and stable.The steel base was sintered to a layer of CuPb10Sn, then cooled and pressed onto a layer of material, and finally shaped, and then rolled into shape.
You can choose, and choose the galvanized steel base outside, or copper plating, in order to achieve better surface salt fog test requirements, you can choose special material to reach to the requirement of the friction in the part of the parts, you can also customize the thickness of the copper powder, improve performance of shaft oilless bearing strength, so contact us, we can help you to design the bearing.
