PVB014 Steel Back PTFE Metal Polymer Composite Self Lubricating Plain Bushing for Shock Absorber
PVB014 Self lubricating bearing is made of steel back as base material, sintered bronze powder as middle layer and PTFE mixture as sliding layer. This type of sliding bearing is special designed for reciprocating motion conditions. It's also called DP4 DU bushing, sliding bushing,oil free bushes,SF-1 oilless bearing,PTFE coated self-lubricating bearing,pilot DU bearing,damper bushing bearing and metal polymer composite DU bearing.
Material 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
PVB014 bushing 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 bushing can protect the mating surface from wearing.
Particularly suitable for reciprocating movement.
Availability
Application
PVB014 self lubricating bushing is particularly apply for reciprocating movement products, such as shock absorber of automobiles & motorcycles, pneumatic cylinder and so on
