Forged Steel Components: The cylinder barrel (tube) and piston are manufactured from high-strength, forged steel. The forging process aligns the metal's grain structure to the shape of the part, resulting in superior strength and exceptional resistance to impact and fatigue failure under high-load conditions.
LaserClad™ Piston Rod: This is a flagship technology. The piston rod is treated with Caterpillar's proprietary LaserCladding process. A wear-resistant alloy is metallurgically bonded to the rod surface using a high-power laser. This creates a surface that is significantly harder, more abrasion-resistant, and far more resistant to corrosion and pitting than traditional hard chrome plating.
This 419-5749 boom cylinder is used for 349 excavator.
