Product Introduction

Our hard chrome-plated hollow piston rods adopt premium materials including C45E, 40Cr4, 42CrMo4 and 25Mn, supporting customized specifications with diameters from 20mm to 500mm and lengths from 200mm to 20000mm. Single-layer and double-layer hard chrome plating are available, with precise coating thickness ranging from 0.02mm to 0.05mm. The chrome coating features high hardness of 800-1150 HV and ultra-smooth mirror surface finish with Ra 0.05, effectively reducing friction and seal wear. With 100-200 hours NSS resistance, the product delivers excellent anti-corrosion performance. The optimized hollow structure reduces weight and energy consumption while maintaining stable mechanical strength, perfectly suitable for various heavy-duty hydraulic machinery and harsh working conditions.
