Product Description
Self-lubricating, oil-free, low cost, self-lubricating composite oil-free bearings that you have to choose from http://www.bronzegleitlager.com/
The oil-free bearing is a sliding bearing made of steel plate, sintered spherical bronze powder in the middle, and a mixture of PTFE 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.

Poly tetra fluoroethylene(PTFE)
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, ptfe 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 CuPb10Sn PTFE + Steel + self - lubricating oil - free bearing bearing of the molding process
CuPb10Sn PTFE + 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 PTFE material, and finally shaped, and then rolled into shape.
