Product Description

Lip Design With Shore Hardness 60 PTFE Banded Piston Applied In Front Shocks Of Cars




Here is the physical properties of our products
Tensile strength ≥23N/mm2
Carrying capacity ≥15N/mm3
Working temperature -80°C to 260°C
Friction coefficient(dry) ≤0.16
Friction coefficient(oil) ≤0.05


packing detail:


1. put piston one by one into environmental plastic box


2. put 5 plastic boxes into standard carton




No scuffing, Custom Shock absorber Pistons can stand fatigue test and blow-off test




•      Front shock absorber piston


•      Conventional design


•      With PTFE banded on OD


•      We can produce according to the customer's drawing


•      Middle part (sinter part), we can use the material as the customer's demand


•      Carbon content is 0.1%, copper content is 3% or other choice




1. Wear and corrosion resistance


2. Efficiency steaming treatment


3. Reduces friction and ensure smooth rod reaction


4. PTFE banded piston


5. It is equipped with piston rings to provide a good seal between the cylinder wall and piston


6. Increased seal durability


We own the following testing equipment to assure the quality and properties of the mixed material and


banding effectiveness.


Inspection equipment:


1. Tensile strength testing machine


2. Abrasion & friction coefficient testing machine


3. Shore durometer


4. Rockwell hardness tester 


5. Density balance


6. Fatigue testing machine


7. Blow-off & friction testing machine


Main property for our shock absorber spare parts:


1. Density of powder metallurgy piston: not less than 6.3g/cm3


2. Density of powder metallurgy valve seat: no less than 6.5g/cm3


3. Density of powder metallurgy rod guide: no less than 6.6g/cm3


4. Efficiency steaming treatment and surface treatment




In car or motorbike front or rear shock absorbers


Competitive Advantage:


1. Consistency in size.


2. Infrared ray detect the out diameter in automatic banding machines


3. Produce PTFE disc by ourselves, can control the quality itself.
