Forged & Machined Hydraulic Cylinder Piston
Product Introduction
Forged & Machined Hydraulic Cylinder Piston represents a premium-grade component engineered for maximum strength, impact resistance, and precision fit. Combining hot forging with high-precision CNC machining, this type of piston is ideal for high-pressure hydraulic systems where durability, safety, and service life are paramount.
Forging improves the internal grain structure of steel, enhancing mechanical properties such as fatigue resistance and tensile strength. After forging, each piston undergoes precision machining to achieve exact dimensional tolerances, custom groove profiles, and a refined surface finish suitable for tight seal engagement and low friction operation.

Product Description
Pistons the power house within. Designed to with stand immense pressure, it transforms hydraulic energy into mechanical force with unparalleled precision. Our pistons are engineered to deliver consistent performance, even in the most demanding applications.
- Raw Material Selection – Alloy steel blanks such as 42CrMo or 4140.
