High-Precision Chrome Plated GCr15 Piston Rod – Hardened & Ground for Hydraulic Systems

Product Description：

This high-performance piston rod is manufactured from premium GCr15 bearing steel, engineered for extreme durability and precision in demanding hydraulic applications. The shaft undergoes a multi-stage finishing process: first high-frequency induction hardening to achieve a surface hardness of HRC 58–62, followed by precision grinding to ensure dimensional accuracy and surface integrity, and finally hard chrome plating for superior wear resistance and corrosion protection. With a diameter of 92 mm and length of 2870 mm, this rod is ideal for heavy-duty hydraulic cylinders, injection molding machines, and industrial automation equipment requiring long service life and minimal maintenance.

Specifications：

-       Material: GCr15 Bearing Steel (Equivalent to AISI 52100 / DIN 100Cr6)

-       Dimensions (Diameter x Length): Ø92 mm x 2870 mm

-       Surface Hardness: HRC 58–62 (After High-Frequency Quenching)

-       Surface Treatment: Hard Chrome Plating (Thickness: 20–40 μm typical)

-       Surface Finish: Ra ≤ 0.4 μm (After Precision Grinding & Plating)

-       Machining Process: High-Frequency Induction Hardening → Precision Grinding → Hard Chrome Plating

Key Features & Advantages:

-       Exceptional Wear Resistance: The combination of high-frequency hardening and hard chrome plating ensures the rod withstands continuous friction and abrasive environments without premature failure.

-       Superior Corrosion Protection: Hard chrome layer provides a dense, non-porous barrier against moisture, chemicals, and oxidation, extending service life in humid or corrosive conditions.

-       Dimensional Stability & Precision: Precision grinding after hardening guarantees tight tolerances and smooth surface finish, critical for sealing performance and system efficiency.

-       High Load-Bearing Capacity: GCr15 steel’s inherent strength and toughness, combined with surface hardening, allow the rod to handle high dynamic loads without deformation or fatigue.
