Product Name: piston 27#
Place of Origin: Ningbo,China Category name: Shock absorber piston Model: XY-D27XD8X14
filled PTFE Suspension Piston banded piston produced by skirting machine apply in automotives rear shock absorber
Xia Yi produce shock absorber pistons, PTFE piston rings and related powder metal parts.
Pistons are used in front or rear shock absorbers from different automotives.
One of the most important type of shock absorber that is used by the manufacturers is non-
pressurized twin tube hydraulic shock absorber.This shock absorber comprises of a cylinder
with a piston moving inside it.The piston on the other hand consists of orifices that enables
the fluid to flow between the compression and rebound chambers.The displaced oil is collected
in the storage tube whereas the heat so generated is dissipated to the atmosphere.
