Hydraulic Cylinder Piston Rod: Precision & Manufacturing

The hydraulic cylinder piston rod is like the rockstar of the hydraulic world – it’s the mover and shaker behind every hydraulic operation. But how exactly is this crucial part made? Let’s dive into the wild world of piston rod manufacturing!

Three types of hydraulic cylinder piston rods.

Solid piston rod.

Hollow piston rod. It is assembled and welded by the rod head, shaft and rod end.

Hollow piston rod with oil inlet tube. It is assembled and welded by the rod head, shaft, rod end and oil inlet tube.

The hydraulic cylinder piston rod is a critical component with exacting standards. Here’s a streamlined breakdown of its manufacturing process:

Raw Material Preparation: Selecting quality materials like CK45, 4140, or SS304.
Assembly and Welding: Precisely assembling and welding components according to specifications.
Heat Treatment: Applying heat treatment methods like normalizing or quenching for optimal strength.
Turning: Precision machining to shape and refine the rod.
Grinding Before Chrome Plating: Ensuring smoothness and uniformity before plating.
Chrome Plating: Adding a protective and decorative chrome layer.
Final Grinding: Fine-tuning dimensions and surface finish.
Patching: Repairing any imperfections to meet quality standards.
