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
