High Quality Low Price ISO Standard Hydraulic Cylinders
Before hydraulic cylinder is assemblied , every spare parts would be measured and cleaned .After hydraulic cylinder is assemblied , pressure test would be carried out one by one.
We ensure the testing pressure is 30%-50% higher than rated pressure in almost one hour's test.
High Quality Low Price ISO Standard Hydraulic Cylinders
Product Description
1. Working pressure: 7Mpa-35Mpa;
2. Bore: 14-800mm;
3. Stroke: <=15000mm;
4. Mainly used for engineering equipment, agricultural vehicle.
Usages and features:
1. Pressure: This standard cylinder had two kinds of pressure levels for E and G.
E-class applied to pressure more than 6.3Mpa~16Mpa of the hydraulic cylinder (E-cylinder).
G-class applied to pressure more than>16Mpa~25Mpa of the hydraulic cylinders (G-cylinder).
2. Seal:
E-cylinder use Y type polyurethane seals ring, which has simple structure and good abrasion resistance
and Y type rubber sealing ring, which is used widely;
G-cylinder uses V type obturating ring assembly which has high temperature and reliable seal.
3. Dustproof: These hydraulic cylinders use polyurethane or nitrile rubber non-frame-type dust ring.
4. Applicable medium: hydraulic oil, mechanical oil, emulsion. It is not appled to phosphate esters.
5. Applicable temperature: -40-120.
