What are the material options for hydraulic cylinders?

The hydraulic cylinder is an important actuating component in a hydraulic system, used to convert hydraulic energy into mechanical energy to achieve actions such as pushing, pulling, and lifting objects. When choosing the material of a hydraulic cylinder, factors such as the working environment in which the cylinder is located, usage requirements, the load and pressure it bears, etc. need to be taken into consideration. Different materials have different characteristics and applicability, so there are certain considerations in material selection. The following will provide a detailed introduction to the material selection of hydraulic cylinders.

The materials of the main components of a hydraulic cylinder include the cylinder tube, gland, piston rod, piston, etc.

The cylinder tube is the main part of the hydraulic cylinder and is usually made of high-strength seamless steel pipes, such as No. 45 steel, 40Cr, etc. In cases where hydraulic cylinders have particular requirements, materials like aluminum alloy or stainless steel can also be utilized.

The end cover is divided into the front end cover and the rear end cover. Its main function is to seal both ends of the hydraulic cylinder and prevent the leakage of hydraulic oil. End covers are usually made of cast iron or aluminum alloy materials.

The piston rod is an important moving part of the hydraulic cylinder and is usually made of high-strength alloy steel, such as 40Cr, 42CrMo, etc. Materials such as stainless steel or titanium alloy can also be used for hydraulic cylinders with special requirements.

The piston is the main component of a hydraulic cylinder and is usually made of wear-resistant, corrosion-resistant and high-strength materials, such as cast iron, aluminum alloy, steel, etc.

When choosing materials for hydraulic cylinders, factors such as material cost, processing difficulty, maintainability, and reliability also need to be considered. Selecting the appropriate material ensures that the hydraulic cylinder can work stably and efficiently. TOLENG is a professional manufacturer of hydraulic cylinders.
