Robust Construction for High-Impact Loading:
Laser-Clad Piston Rod Technology: A premier feature on the 349D. The piston rod is likely treated with Caterpillar's proprietary LaserCladding process. This involves metallurgically bonding a wear-resistant alloy onto the rod surface with a laser. It offers far greater resistance to abrasion, corrosion, and pitting compared to traditional hard chrome plating.
Optimized Size and Strength: The cylinder is designed with a large bore diameter to generate the massive force required for powerful bucket curling. The rod is also sized to withstand significant side loads experienced during uneven digging or when using attachments like breakers or thumbs.
This 357-9784 bucket cylinder is used 345D 349D 349D2 345C excavator.
