Low friction and good seal special design 35# automotive Shock Absorber Piston


We are engaged in developing and manufacturing different kinds of shock absorber pistons,


Powder metallurgy based, with PTFE material banding outside, using a special way to combine them


together. They have advantages of low friction, good seal etc.


The products have passed the Test center, Shanghai Plastic Research Institute. We have testing


machines in our company too and have set up good cooperative relationship with some big shock


absorber factories home and abroad.


Our mass production piston types are: Φ25, Φ27, Φ30, Φ31, Φ32, Φ35, Φ36, Φ40, Φ45......


At this moment, we can produce bigget size is 60mm


SPEC: D35XD12X14


•      The pistons are sold to secondary market


•      Diameter must be coaxial A=0.05


•      Even banding surface


•      Net weight is 38.5g


•      Pistons can do frictional performance test according to the customer's demand.
