40mm height density 6.5 band PTFE disc Piston without any defect after durability test

Specifications:

• high shock absorber piston
• new 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

Description:

Shock absorber piston oil cylinder piston with density 6.5g/cm³ band PTFE disc on OD

The detail information of the pistons:

1. Size: D31XD28X45

2. Material: PTFE PTFE

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

4. Using the testing ring, 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.

Xia Yi, found in 2006, 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

work efficiency. We have a technical team to develop automatic machine and we improve our pressing

machine and other machines to lower the cost and improve efficiency.

Advantages:

1. Consistency in size

2. Infrared ray detect the diameter

3. Strict control plan

4.100% testing for outer diameter

Applications:

Car or motorbike shock absorbers

Competitive Advantage:

Proper fillers can reach good seal and friction

Tooling designed by XIAYI can assure the delivery date

A whole set of testing equipment
