Advantage:
Unmatched Contamination Control: Critical for longevity in abrasive environments, preventing internal damage and extending seal life.
Absolute Load-Holding Security: The sealing system ensures the boom will not settle or creep down, even when holding maximum rated loads at height for extended periods. This is a paramount safety and performance feature.
Peak Hydraulic Efficiency: Minimal internal leakage ensures that nearly all hydraulic power is converted into productive lifting force, maintaining performance and reducing heat load on the entire hydraulic system.
This 311-9526 boom cylinder is used for 336D 330D 340D 330C 336D2 excavator.
