F50 - U3 - 64 customized shock piston bands with low wearing and friction coefficient
We can do blow off testing for shock absorber pistons.
The purpose of this test is to determine the pressure needed to blow the PTFE band of the piston when
traveling in the pressure tube. The test is performed with a constant lateral force applied to the piston
during the pressure build up over the piston. The test is stopped when the pressure decreases due to
PTFE band failure.
Specifications:
| Physical performance for shock piston | tensile strength | More than 18MPa |
| elongation @ break | More than 160% | |
| shore hardness (bands) | 57 - 61 | |
| density | 2.06 – 2.19 g/cm3 | |
| wear | Less than 50mg | |
| friction coefficient | Less than 0.2 | |
| hardness (sinter piston) | HRB60-80 | |
| Technical requirements for sinter piston | Raw material F50 - U3 - 66 or FC - 0208 | |
| Steam treatment | ||

Description:
XIAYI company is specialized in design and producing PTFE banded shock absorber pistons,at the same
time,we design and manufacture automatic skirting machines.
Till now we have produced so many different types of shock absorber pistons with the diameter from
ø20mm~ø50mm.We make PTFE discs and toolings in our own factory,can control the quality effectively
and also can save much time.
D31 PISTON:
RAW MATERIAL OF SINTER PARTS:IRON BASED,IRON & COPPER BASED,COPPER
BASED,STAINLESS STEEL BASED
RAW MATERIAL OF PTFE DISC:
PTFE+BRONZE
PTFE+CARBON
PTFE+GLASS FIBER
PTFE+OTHER fillers according to cutomers’ demand
The detail information of the pistons:
1.Used in front shock absorbers
2.When temperature reach 100℃,expansion ratio ≤+/-1%
3.Using the testing ring,with the shock absorber oil,max frictional force is 15N
4.Piston can get through freely of the certain size of cylinder with 2N force
5.PTFE tensile strength ≥18MPa,elongation @ break ≥200%
6.Tight integration between piston and PTFE disc.PTFE won't fall off when working in the cylinder.
Applications:
Car or motorbike shock absorbers
Competitive Advantage:
1. Consistency in size
2. Infrared ray detect the diameter
3. Strict control plan
4.100% testing for outer diameter
