Product size

Features

1. Changed copper bearing and use DU bearing.

2. Changed NBR seal and use PU seal.

3. Changed anti-friction seal and use new POM anti-friction seal.

4. Using new SDA rolling technique for the piston rod and piston.

5. Using SDA rolling technique for the tail barrel (S＞100, end cover use snap ring structure).

6. Gasket use SDA anti-collision gasket structure.

7. Barrel appearance is same with SMC new type-CQ2 series,easy to install the sensor and save material.
