We are a professional factory engaging in producing reliable suspension absorber pistons, with many

years’ experiences in this line. The pistons can be used in front or rear shock absorbers from SUBARU,


We own a strong team to research and develop automatic machines. We have more than ten machines

now and the annual capacity can reach over 15,000,000 PCS.

SPEC: D22XD6X10.5

• 6 pairs of holes

• All the holes are inclined

• The pistons are exported to Japan

• Net weight is 21.5g

• We can do drawing load test for banded piston with no band slippage after test.


Complex multi-level design

Flexile and convenient logistic service

Significant increase in lifetime

Standard material according to technical drawing

Can absorb most shake when driving

Increased seal durability

Processing of sinter parts:

Powder blending—forming—Sinter—Sizing—Machining—Steam treatment—Oil impregnation

Process of PTFE banding:

Powder blending—PTFE cylinder compression—Sintering—PTFE disc production—repressing—heat







OTHER material or fillers


Used in car or motorbike shock absorbers

Competitive Advantage:

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

time XIAYI can design and produce automatic banding machine and non-standard testing machine, can

test drawing force testing and oil immersion testing.
