Description:

XIA YI is engaged in developing and manufacturing different kinds of shock absorber pistons. Powder

metallurgy based, with PTFE material banding outside, they have advantages of low friction and good

seal properties. In our company, we can test density, friction coefficient, abrasion, blow-off testing and so

on, other items that we can’t test by ourselves we will send standard sample blocks to Shanghai Plastics

Research Institute. We have set up good cooperative relationship with some big shock absorber factories

home and abroad. Our mass production piston types are: ø25, ø27, ø30, ø31, ø32, ø35, ø36, ø40, ø45,

ø46.

SPEC: D25XD8X11.5

Unique design for the fluid channels

Material of sintered piston: Fe-C-Cu

Density is 6.0 g / cm3

Steam treatment

Net weight is 24.32g

Applications:

In car or motorbike front or rear shock absorbers

Competitive Advantage:

1. Consistency in size.

2. Infrared ray detect the out diameter in automatic banding machines

3. Produce PTFE disc by Xia Yi, can control the quality itself.
