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.

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

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
Pvb-010 steel back self-lubricating bush (du bushing)
Structure:
1.Ptfe/pb mixture 0.01~0.03mm as sliding layer, provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming homogeneous oxide type solid lubricant film.
2.Porous bronze 0.2~0.3mm, provides max. Thermal conductivity away from the bearing surface, also serves as a reservoir for the ptfe-lead mixture.
3.Low-carbon steel backing 0.7~2.3mm, provides fundamental structural support and gives exceptionally high load carrying capacity, excellent heat dissipation.
4.Tin-plating 0.005mm or copper plating 0.008mm, provides good corrosion resistance.
Characteristics:
Good wear and friction performance over a wide range of loads, speeds and temperature without oil
Also perform well with lubrication
Maintenance-free, long life
Availability:
Standard cylindrical bushing, flanged bush, thrust washers and strips are availabe
Lead free type is also available

Structure:
High strength brass alloy base+solid lubrcants
Characteristics:
Exhibits incomparable performance under a high load, low speed operation. Also perform well without lubrication,
Excellent wear resistance in such places where an oil film is difficult to be formed due to reciprocating, oscillating motions and frequently intermittent operations
Remarkable resistance to corrosion and resistance to chemical attack
Maintenance free and save operating cost.
Availability:
Cylindrical bushing, flanged bushing, thrust washer and slide plate are standard fabrication.
Special designs can be made according to your design.
Sleeve & Bearing & Bushing
Rock Metal offers a wide selection of sleeve & bearing & bushing. They are simplest design of bearing, sleeve-shaped. They are usually found in applications that use rotating or sliding parts. They are made from a range of materials: sic, carbon, tc, ceraic, stainless steel, etc
