SANY Genuine Heavy-Duty Dust Seal (60065345)
The SANY Genuine Metal-Clad Dust Seal (60065345) serves as the critical outermost barrier for excavator hydraulic cylinders. Engineered with a precision-molded wiping lip bonded to a structural steel frame, this seal prevents abrasive mud, sand, and grit from damaging cylinder rod surfaces and internal high-pressure seals.

Models: SY55, SY60, SY65, SY75, SY95 series.
Applications: Boom, arm, and bucket hydraulic cylinder assemblies.
Diagnostics & Repair
Service Indicators:
Leakage: Oily mud buildup or dripping fluid at the cylinder gland.
Degradation: Visible cracks, tears, or outward rolling of the wiping lip.
Rod Damage: Dull lines or scoring appearing on the chrome rod surface.
Recommendation: Always replace the dust seal as part of a full Cylinder Repair Kit to ensure comprehensive hydraulic integrity.
