Piston rod is used to transfer the force of the parts, required to withstand the extension, compression, vibration and other loads, surface wear-resistant, no corrosion, generally choose carbon steel, fine rolled stainless steel and other materials, steel surface need chrome plating and tempering heat treatment。

The strength of the piston rod must be paid attention to when the cylinder is used。

1, due to the piston rod head thread connection is damaged by the impact of habitual load;

2, when bearing the thrust load, attention should be paid to the stability of the slender rod;

3, when the cylinder is installed horizontally, the piston rod protrudes due to its own weight caused by the piston rod head sag problem。
