XIA YI company produces various kinds of shock absorber pistons,banded 

pistons.Based with sinter parts,banded PTFE wafer around the sinter parts,with the 

advantage ofhigh load capacity,good wear resistance,low friction coefficient and so 

on.Pistons can be used in front or rear shock absorbers.

We can produce the piston according to customer's drawings.
