Massive Load-Bearing Capacity and Robust Design:
Extreme Strength Construction: The cylinder barrel is a high-strength steel tube designed to contain very high hydraulic pressures. The piston rod is exceptionally large in diameter and made from hardened, high-tensile strength steel to resist bending under extreme loads.
Superior Rod Hard-Chrome Plating: The piston rod features a thick, hard-chrome plating. This is crucial for resisting wear, abrasion from the environment, and corrosion. A flawless rod surface is vital for maintaining the integrity of the rod seals, which hold back tremendous pressure.
Withstands Shock Loads: The design accounts for significant shock loads that occur when the boom is stopped suddenly with a heavy load or during aggressive digging.
This 349-4126 boom cylinder is used for 320D 323D 320D2 320GC excavator.
