Du Bushing

DU bush sliding bearing is of high safety factor , and is particularly appropriate for high temperature environment where no oil is efficient and where the machine must be under successive long period working condition . This is widely used in steel metallurgy industry such as bushes for roller grooves of successive casting machines , cement grouting pumps and screw convery ers for cement . It can also be composed in steel housing or fabricated into flanged bushes which can move both in radial and in axial directions.

Pvb-014 shock absorber bushes, reciprocating motion bushing

Structure:

1.Ptfe with cooper 0.01~0.03mm
2.Porous bronze 0.2~0.3mm
3.Steel backing 0.7~2.3mm
4.Tin-plating 0.005mm or copper plating 0.008mm

Characteristics:

This type bush is efficient even under sudden break off the oil lubricating, wear
Resistant, which can keep the lubricating oil clear after long period
Of working.
This bush can protect the mating surface from wearing.
Particularly suitable for reciprocating movement.

Availability:
Standard cylindrical bushings, flanged bushings, thrust washers and strips are availabe
Special designs are produced at short notice
Lead free type is also available

Applications:
Particularly apply for reciprocating movement products, such as shock absorber of automobiles & motorcycles, pneumatic cylinder and so on

Jf-800( pvb031) bimetal bush
Structure
Metal backed with bronze graphite oilless bearings
1.Sinter bronze with graphite: good wear resistance with lower friction and excellent load carrying capacity. Bimetallic bushing can be machined after fitting to get precision tolerance. We also can supply the bearings with ptfe or graphite sprayed layer on the work surface to get much lower start friction.
2. Metal backing: gives exceptionally high load carrying capacity, excellent heat dissipation.
3.Copper plating 0.002mm, good corrosion resistance.

Bearing surface
The standard bearings we supply as plain surface, also we supply with cleaning grooves for small angular movements or in the presence of abrasive media or dirt, and indented surface for grease lubricated applications.

Indented surface for grease lubricated applications.

Cleaning grooves for small angular movements or in the presence of abrasive media or dirt.
Application
The special structure of the material suitable for hostile environments, for high load application which lubrication is difficult. Now jf-800 bimetallic bush has been widely used in water turbines, vane controls, injection molding machinery, packing machines, construction equipment, tire moulds, paper production machinery, furnace expansion plates, automotive transmission, heavy lifting chain linkage, food production equipment etc.

Availability:

1. Standard cylindrical bushings, thrust washers and strips are availabe
2. Special designs are produced at short notice
