42CrMo4 Chrome Piston Rod Chrome Plating F7 Tolerance For Plunger Cylinder
The product surface is specially ground and is processed by hard chromium plating technology, and then it is mirror polished, with characteristics of friction resistance and corrosion resistance. The piston rods can be used as guide rods and post rods for all kinds of air cylinders, oil cylinders, packaging machines, woodworking machines, textile machines, printing and dyeing machines, die-casting machines, injection molding machines, and other machines, etc.
Chrome Piston Rod Features
The Hard Chrome Plated Piston Rods are fabricated using optimum quality raw material and latest machinery. The bars undergo rigorous processes like pilling, straightening, grinding, polishing, hard chrome plating, and finishing under the supervision of experienced engineers.
Hard Chrome Plated Piston Rods are widely used in hydraulic and pneumatic cylinder, printing machinery, textile machinery, engineering machinery, woodworking machinery, etc. Our products are highly appreciated by our clients for their features like corrosion resistance, robust construction, elevated durability, high tensile strength and mirror-like surface.
