Why do excavator hydrauliccylinders fail?
(1) Seal Wear: Over time, seals deteriorate from pressure and heat, leading to internal or external leaks.
(2) Physical Damage: Impacts from falling debris or collisions with other machinery can dent the cylinder, preventing smooth piston movement.
(3) Contamination: If the cylinder barrel is not properly cleaned during assembly or maintenance, debris or metal shavings may scratch the inner wall. This can cause scoring, leading to seal failure, internal leakage, and reduced performance.
(4) Bent Rods or Misalignment: Excessive side load or poor installation can cause rod bending, making it difficult for the piston to operate normally.
Regular inspection, cleaning, and proper installation are key to extending cylinder lifespan and avoiding costly repairs.
