Value Bushing Steel Backed Ptfe Lined Bronze And Brass Bushings-Stainless Steel 316


Steel Backed Bushing High performance steel reinforced DU bushings, environmental protection is based on steel substrate, central bronze powder, sintered spherical surface that rolls four ethylene (PTFE) and a mixture of green polymeric material, bearing rolling and sliding. The product is lead-free environmental protection, the wear-resistant performance is excellent, a plastic layer and a copper layer with high strength, fatigue resistance, impact-resistant performance are a good way to an advantage.

Operating temperature range: -90 ° C ~ 180 ° C


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.

Characteristics

Suitable for use in fatting or lubricating conditions, high bearing capacity, good wear resistance;


Suitable for rotating, reciprocating and swinging and other forms of movement and frequent starting, intermittent movement or heavy load and other occasions which are not easy to form oil film lubrication;


High load, low speed lubrication conditions with stable low friction coefficient and excellent wear resistance;


Friction surface layer can be secondary processing, bearing into the seat hole after processing, can further improve the accuracy of fit;


Long working time under boundary lubrication conditions, such as in the process of regular grease maintenance, can extend the service life;


Bearings for thin-wall structure, light weight, occupies a small volume, suitable for compact design;

Good dimensional stability, high mechanical strength;
