Product Overview
CK45 Hard Chrome Plated Rods are high-performance piston rods widely used in hydraulic cylinders, telescopic cylinders, machinery shafts, and linear motion systems. With high surface hardness, strong corrosion resistance, and superior straightness, these rods can be manufactured as solid piston rods or chrome hollow rods, depending on your design requirements. Our CK45 hard chrome hollow rod is produced using high-quality seamless mechanical tubing and undergoes strict grinding, hard chrome plating, and polishing processes to meet tight tolerances and demanding industrial standards.
