Lead-free and oil-free compound bearings are widely used in food machinery and pharmaceutical machinery due to their excellent properties such as high wear resistance, corrosion resistance, and low friction. These bearings are made of environmentally friendly materials that do not contain harmful substances such as lead, ensuring the safety of food and pharmaceuticals. Additionally, the oil-free design eliminates the need for lubrication, reducing maintenance costs and enhancing equipment reliability. Overall, lead-free and oil-free compound bearings are an ideal choice for ensuring the smooth and safe operation of food and pharmaceutical machinery.
Oil-free, environmentally friendly, self-lubricating oil-free bearing, low friction, low cost.
Is based on the material according to the international environmental protection requirements and the development of a new product.This product is widely used in general machinery, food machinery, pharmaceutical machinery, tobacco machinery in particular, lead-free effect in line with European environmental protection requirements, is the direction of the development of oil-free lubrication bearings.
CuSn6.5P0.1+Steel Principle of compound oil-free self-lubricating bearing
Introduction to metal composition of lead-free self-lubricating bearings
| CuSn6.5P0.1 |
| Cu(%) | Sn(%) | P(%) | other(%) |
| rest | 6~7 | 0.1~0.25 | ≦0.5 |
Poly tetra fluoroethylene()
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.

Let's look at CuSn6.5P0.1+ + Steel + self - lubricating oil - free bearing bearing of the molding process
CuSn6.5P0.1 + 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 CuSn6.5P0.1, then cooled and pressed onto a layer of material, and finally shaped, and then rolled into shape.
self - lubricating oil - free bearing bearing Additive PB
Polybutylene,PB
Application: oil additive, intermediate of oil additive;Raw materials for lubricating oil, adhesives and plasticizers;It can also be directly used as lubricant, impregnated oil in high voltage cables, compressor oil;No smell, non-toxic, can be used with food contact paper processing;
Features: colorless or light yellow viscous liquid, odorless or slightly stinky
You can choose from a variety of customized oil-free bearing services, such as copper plating on steel or zinc plating
You can choose the mechanism of self-lubricating oil-free bearing
