Product Description

Shock Absorber PTFE Composite Metal Polymer Plain Bearing DU Bushing

 

 

ZR-014 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


 

Steel Back PTFE Lined Bearings  Polymer Composite Plain Bearing For Shock Absorber 0

 

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


ZR-014  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.
