Critical Performance Objectives
Debris Scraping: Clears mud, silica sand, and grit during cylinder retraction to prevent chrome scoring.
System Isolation: Protects internal main seals, buffer rings, and guide strips from contamination.
Moisture & Oil Control: Reduces external weeping by capturing residual micro-films of hydraulic fluid.
Machine Compatibility
Standard fitment for SANY 9th and 10th generation (C10) mini excavators:
SY55 / SY60 / SY65 / SY75 / SY95 series (-9 and -10 models).
Applications: Boom, Arm (stick), and Bucket hydraulic cylinders.
Professional Maintenance Advice
Service Tip:
For cylinder gland rebuilds, always replace the 60065343 dust seal and 60065345 pressure seal as a pair. Combining a new seal with an old, worn mating component leads to rapid failure and recurrent leaks. If the piston rod shows micro-scratches or burrs, replace both seals immediately to avoid full cylinder pressure loss.
