Porous Sintered Shock Absorber Piston for Hydraulic Suspension Units

Porous Sintered Shock Absorber Piston for Hydraulic Suspension Units

Fluid attack:

A diameter and hardness control is carried out on the band, placed on the piston. Once the PTFE process has been carried out and before 24 hours have elapsed, it is immersed in the fluid for 72 hours at 80 ℃

Acceptance Conditions:

There can be no breakage or detachment of material. The variation of hardness ≤6%, the diameter variation ≤0.20%

Specifications:

100% tested by Go no-Go gauge

Coaxiality can be control within 0.05mm

4 round and square holes

conventional shock piston

net weight is 25.29g

we can do drawing load test for banded piston without band slippage after test.

Description:

Strong R&D team

Responsible staffs

Clean workshop

We will bring you pistons with good quality and competitive price.

Applications:

Car or motorbike shock absorbers

Competitive Advantage:

XIAYI can produce bands rings to low down the cost and control the quality at home, at the same time we

can design and produce automatic banding machine and non-standard testing machine, can test drawing

force testing and oil immersion testing.
