Product Description

Hardened steel bushing with graphite are frequently used in hydraulic cylinders & pivot joints of excavator booms, arms and bucket joints.


Building and mining machines are also often furnished with Hardened steel bushing. Soild Hardened steel bushings repairparts for all kind of machines in cheap price.

Steel - based self - lubricating graphite bearing sleeve

Steel base inlaid bearing, is a reinforced product, with high compressive performance, when working can discharge lubrication particles, so that a layer of diaphragm between the shaft and the sleeve, has the advantage of more anti-bite than monomer oil lubrication, in the support of lifting machinery is particularly suitable.Suitable for the support of winder and crane, but not suitable for use in water or acid and alkali.

Composition of steel (GCr15) Graphite self-lubricating bearing

Lubrication for friction makes the principle of the graphite in PTFE granular, in oil film together play the role of lubrication,

including PTFE filler material has high temperature resistance, low friction characteristics of PB has stained with viscosity and thus form a stable oil film better isolation layer, reduce the movement object in friction between bearings, because of the oil film stability, so has the property of free maintenance.

It can be used to manufacture various bearing rings with wall thickness ≤12mm and outer diameter ≤250mm.


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.



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.
