What materials are used in excavator hydraulic cylinders?
Excavator hydraulic cylinders are primarily constructed from hardened high-strength alloy steel to ensure durability under high-pressure operations.
Cylinder Barrel: Typically made of precision-honed alloy steel or carbon steel, offering high fatigue strength and resistance to internal pressure.
Piston Rod: Manufactured from chrome-plated hardened steel, often achieving surface hardness up to HRC 55, which enhances wear resistance and corrosion protection.Many different metals are used to make the cylinder rods, but most commonly, theyare made of steel or stainless steel and then coated with a type of chrome material.
Rod Coating: The rod surface is usually treated with hard chromium plating to reduce friction and extend service life.
