Introduction
Hollow piston rod is pipe rod, outside plated chrome and inside hole is no honed. It is used for telescopic cylinder rod. Inside hole is used for passing oil . The product has high surface hardness, high temperature resistance and corrosion resistance, and is suitable for elevator cylinders and telescopes Oil cylinders, telescopic ladders, agricultural machinery, earth-moving machinery, etc..
