Features Made of high quality aluminum alloy cylinder, sturdy, anti-corrosion and not easy to rust. With the increase of pressure, it automatically improves the sealing performance and lasts for a long time. Adopt high-precision steel ball zero clearance slide rail, work smoothly, steel ball will not fall easily. The surface of the cylinder has increased the hard oxidation technology, which increases the surface hardness of the cylinder, not easy to deform. The center of the cylinder body is formed once, the hole pitch is accurate, and the sealing is strong. Made of high quality aluminum alloy cylinder, sturdy, anti-corrosion and not easy to rust.
