Product Description

Aging resist and no - sticky PTFE banded piston without steam treatment HRB60 used in car



PTFE piston bands is a new technology.It changes the traditional method,can band outside of sinter


piston.Main material is PTFE,can add different filler such as carbon fiber,glass fiber,graphite,bronze and


so on.Piston rings with different filler are used to different using area,they have different advantages.


Normally,PTFE+proportional graphite+proportional copper,this is a piston ring,used in shock absorbers.



Here is the physical properties of our products

Aging resistance and no-sticky powder metallurgy PTFE banding piston D32 auto Shock Absorber Piston


We mainly produces shock absorber pistons with many different dimensions.


We have a strong technical team to develop automatic skirting machines which can assure the


consistency of the pistons and also can improve the work efficiency. Compared with other suppliers, we


are sure we can offer you the more competitive price and quality.


Piston is based on powder metallurgy, filled modified PTFE material, using a special way to combine them


together, which has dual advantage of powder metallurgy and PTFE.


(1)Advantage of powder metallurgy:


Unique chemical composition and mechanical physical properties


(2)Advantage of PTFE:


Chemical and aging resistance, temperature endurance and no-sticky performance


(3)Advantage of piston:


High carrying capacity, good wear resistance, low friction coefficient, good seal and so on


SPEC: D32XD8.5X13.5


Inclined holes design


The pistons are used for primary market


Lateral force 800N added after piston is closed in dampers, amplitude +/-25mm


Piston ring don't drop down and no abnormal abrasion after 4 million times vibration


Net weight is 35.58g


Test Ability:

Carbon sulfur determinator

Metallurgic microscope

Hydraulic universal material tester

Hardness testers

Pneumatic measuring instrument

Measuring projector

Electrical profilometer


Durability test:

side load 30kgf
duration 3 million cycles
no band peel off or breakage after test




Car or motorbike shock absorbers


Competitive Advantage:


We are professional company which produces different size and design for shock absorber pistons.


We have a complete set of testing equipment which can control the quality for the material.
