Choosing the Right Piston Rod

Piston rod hardness testing: Hardness tester measurement is usually divided into two types: destructive measurement and non-destructive measurement. Non destructive measurement has less damage and cannot achieve complete non damage. Compared to the shaft in the middle of the piston, this injury is fatal, so only destructive measurement methods can be used.

Manufacturing process

Outer diameter of 20-500mm, length of 600-15000mm, precision slender shaft and piston rod. We use professional processes such as precision cold drawing, precision grinding, and high-precision polishing to manufacture, and all technical indicators meet national standards.

Design of Piston Rods

1. The purpose of the equipment and the conditions of the workpiece.
2. The structural characteristics, load conditions, required speed, size stroke, and action requirements of the working organization.
3. The selected hydraulic system working pressure.
4. The current status of materials, accessories, and processing techniques.
5. Relevant national standards and technical specifications, etc.
6. Efforts should be made to ensure that the piston rod can withstand very large loads in a high load state, and has good longitudinal stability in a high pressure state.

Applications of Piston Rods

This product can be directly used in industries with precision slender shafts as components, such as oil cylinders, air cylinders, shock absorbers, textile printing and dyeing, printing machinery guide rods, die-casting machines, injection molding machine guide rods and top rods, four column press guide columns, fax machines, printers and other modern office machinery guide shafts.
