The materials used in Allco cylinders for mining trucks and crushers are selected to withstand extreme pressure, temperature variations, corrosion, and abrasive conditions. The combination of high-strength materials like alloy steel and nickel/chrome-plated rods, specialized materials like polyurethane, nitrile rubber and Viton for gaskets and seals, along with a robust and thoughtfully engineered cylinder structure, ensures that these hydraulic components can operate reliably under the extreme conditions.
