Skew oil hole design banded piston with skirting PTFE used in car shocks

Specifications:

Description:

High quality shock absorber piston, used in various cars and trucks

Properties of banding ring can be tested in our company, we have the following test equipment:

Tensile strength testing machine, friction & abrasion testing machine, density balance, coefficient of linear

expansion testing machine and so on.

We also design and manufacture non-standard testing machine which can do blow-off test after banding.

Adhesion test: ring must be tested in shock absorber according to characteristics below:

Piston must have a minimum diameter of groove.

---pressure tube must have maximum internal diameter

---traction force from 4700 to 5390 N and speed=1.5m/s according to condition below

---course =50mm

---frequency =574RPM

---moment must be applied at the end of piston rod = 3Nm

---temperature = 130/160℃

Ring withstand 10min without deformation on adhesion test.

Properties of the banding ring:

Density = 2.03-2.110g/cm3

Hardness = 57-61 shore “D”

Tensile strength = 16Mpa minimum

Elongation = 300% minimum

(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

Applications:

Car or motorbike shock absorbers

Competitive Advantage:

Proper fillers can reach good seal and friction
