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
