Product Details

Automobile Hydraulic Piston is a connecting component that supports the work of the piston. Most of them are used in the cylinder and cylinder movement executing parts. It is a moving part with frequent movement and high technical requirements. The quality of its processing directly affects the life and reliability of the entire product. The piston rod has high processing requirements, and its surface roughness requirement is Ra 0.4 to 0.8 um, which requires strict requirements on coaxiality and wear resistance.
We produce precision long shaft (piston rod) Φ50-Φ300, length 3m-9m, and are manufactured by advanced technology of precision cold drawing, peeling, fine grinding and high precision polishing. The technical indicators of the products meet and exceed the national standards. This kind of piston rod can be directly used for oil cylinders, cylinders, shock absorbers, piston rods, and is widely used in hydraulic pneumatic, textile printing and dyeing, printing mechanical guide rails, fax machines, copiers, printers and other modern office machinery guide shafts, etc. The long axis is the industry and product of the component. The company has an independent electroplating workshop, which is specially designed for the company’s piston rods.

Features:
1. The Automobile Hydraulic Piston is processed by rolling. Because the surface layer has surface residual compressive stress, it helps the surface micro-crack closure and hinders the expansion of erosion. Thereby, the surface corrosion resistance is improved, and the generation or expansion of the fatigue crack can be delayed, thereby improving the fatigue strength of the cylinder rod.
2. The product reduces the friction damage to the seal ring or seal when the cylinder rod piston moves through the rolling process, and improves the overall service life of the cylinder.
3. The product has a variety of different materials to choose from to meet the different needs of customers.

Applications:
Hydraulic Pistons are mainly used in hydraulic and pneumatic, engineering machinery, piston rods for automobile manufacturing, guide columns for plastic machinery, roller shafts for packaging machinery and printing machinery, textile machinery, shafts for conveying machinery, straight lines for linear motion. Optical axis.

Note:
After the piston rod of the hydraulic cylinder is pulled, if it is not treated in time, it will affect the normal use, but the hydraulic cylinder will not work. Therefore, the lighter pull marks can be repaired by local grinding and polishing; for the heavy pull marks, it needs to be repaired by welding and manual grinding.
