27mm OD piston

the pistons are used in industrial radiator

net weight is 28.56g

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

Description:

Xia Yi mainly produces shock absorber pistons, industrial pistons with many different dimensions. Piston is

based on powder metallurgy, filled modified PTFE material, using a special way to combine them together,

which has dual advantage of powder metallurgy and PTFE.

We have a strong technical team to develop automatic skirting machines which can assure the

consistency of the pistons and also can improve the work efficiency. Compared with other suppliers, we

are sure we can offer you the best competitive price. At the same time, we have a whole set of testing

machine in our company to test the banding material.

(1)Advantage of powder metallurgy:

Unique chemical composition and mechanical physical properties

(2)Advantage of PTFE:

Chemical and aging resistance, temperature endurance and no-sticky performance

(3)Advantage of piston:

High carrying capacity, good wear resistance, low friction coefficient, good seal and so on

unique hole design lateral force 800N added after piston is in closed in dampers, amplitude +/-25mm

piston ring don't drop down and no abnormal abrasion after 40,000,000 times vibration

Applications:

Car or motorbike shock absorbers

Competitive Advantage:

Proper fillers can reach good seal and friction

Tooling designed by XIAYI can assure the delivery date

A whole set of testing equipment
