Product Description
We can produce Planetary Screw & Barrel with a wide range sizes of barrel inner diameter, from ø 120mm to ø 350mm. All Planetary Screws & Barrels are made of high quality steel, 38CrMoAlA and 42CrMo, to ensure products have excellent fatigue strength. Sure, good product cann't be without good technics. We adopt advanced processing technics, such as heat treatment, high-frequency quenching, ionic nitriding treatment and so on. These important technics are the key to having good hardness, fine surface roughness and excellent linearity.
Our reliable and helpful screw & barrel is your best choice!
