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, good seal etc.

The products have passed the Test center, Shang hai Plastic Research Institute.Wehave set up good cooperative relationship with some big shock absorber factories home and abroad, such as Russia, UK, Italy, North America, Middle East and some Asia countries.

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

 

SPEC:D32XD8X14

only one hole design   the pistons are sold to secondary market   diameter must be coaxial A=0.05   even banding surface   net weight is 43.76g   pistons can do frictional performance test according to the customer's demand.

Here is the physical properties of our products
Tensile strength	≥23N/mm2
Carrying capacity	≥15N/mm3
Working temperature	-80°C to 260°C
Friction coefficient(dry)	≤0.16μ
Friction coefficient(oil)	≤0.05μ
