This high precision hard chrome plated piston rod is specially engineered for hydraulic press machines that demand exceptional performance, strength, and precision.
The product is manufactured using top-grade black round steel bar and goes through a rigorous process of peeling, centerless grinding, chrome plating, and mirror polishing.
The result is a piston rod with a surface roughness of Ra0.20μm, straightness of 0.2/1000mm, and an f7 tolerance, which meets international quality standards. These rods offer enhanced wear resistance, excellent corrosion protection, and high load capacity.
Ideal for automotive, metalworking, and industrial machinery applications, the chrome plated layer ensures longevity even in high-pressure and high-cycle environments. With superior packing protection and professional after-sales service, this hard chrome plated piston rod is a reliable solution for OEMs and aftermarket replacements.
