32 # teflon banded shock absorber piston with HRB60 - 90 density 6.5g/cm3 used in Car


The bearing material is made from PTFE with a 40% Bronze filling and is specifically designed to support


heavy loads. The exceptional physical properties and PTFE lubricants make the piston bands suitable for


use on rams or pistons in reciprocating applications.


Meanwhile,we can also add other fillers with PTFE,such as glass fiber,carbon fiber,graphite and so on.

Description:


32# shock absorber piston with HRB60-90, density 6.5g/cm3, band PTFE disc on OD used in car shock


absorbers


Xia Yi was found in 2005, after several years’ effort, we have achieved great success in the enterprise.


We increased our workshop this year and developed several new automatic machines which highly


improve our work efficiency.


We have a technical team to develop automatic banding machine and new generation machine has


improved much advantages compared with previous ones. We improve our pressing machine and other


machines to lower the cost and improve efficiency.


The detail information of the pistons:


1. Size: D32, used in automotive shock absorbers


2. Material, GRADE AND COLOR: TEFLON PTFE 6507A NC010 (Dupont)


3. When temperature reach 100ºС, expansion ratio ≤+/-1%


4. Using the testing ring D26.6, with the shock absorber oil, max frictional force is 15N


5. Piston can get through freely of the certain size of cylinder with 2N force


6. PTFE tensile strength ≥18MPa, breaking tenacity ≥200%


7. Tight integration between piston and PTFE disc. PTFE won't fall off when working in the cylinder.


After processing performance can satisfy the following:


1) Stress cracking test 150ºС*500 hours


2) Drawing load test: 39.2 MPa*10,000cycles


3) High vilocity operation, durability test: 1,000,000 cycles


4) Regular operating durability test: 3,000,000 cycles


No band peel off or breakage after test.


Advantages:


1. Consistency in size for the same batch pistons


2. Infrared ray detect the diameter


3. Produce the PTFE disc by Xia Yi can control the quality itself


4. Enough testing machine can assure the material properties


We can use the following material to produce PTFE discs:


We can add bronze powder or carbon fiber or graphite or other fillers in PTFE


Lip design: We can design no lip, single lip or double lip according to the customer’s demand.


Xia Yi produces shock absorber pistons with many different types. These pistons can be used in front or


rear shock absorbers.


We have a strong technical team to research and develop automatic skirting machines. Only need to put


PTFE discs and sinter pistons on table, the machine will do the job to combine them together and finally


get the finished PTFE banded pistons.


Applications:


Car or motorbike shock absorbers


Competitive Advantage:


Unique material for shock piston bands


Pistons are produced by automatic banding machine can assure the consistency of the size
