Symptoms
Major causes
Remedies
Oil is leaking from the pis-
ton rod sliding surface (oil
forms a ring on the piston
rod, which becomes larg-
er and starts dripping)
• Foreign matter is trapped in the inside
diameter of the rod packing or dust
seal.
• Remove the foreign matter.
• Scratching or abnormality of the inter-
nal lip surface of the rod packing or
dust seal.
• Replace the faulty part(s).
• Scratching on the sliding surface of the
piston rod.
• Smooth the sliding surface with an oilstone
(1.6 S or less).
• If the leak persists after smoothing the slid-
ing surface, replace the rod packing and
other seals.
• If the leak persists after replacing the seals,
replace the piston rod.
• Peeling of the hard chromium plated
surface.
• Re-plate the hard chromium plating.
Oil leaking around the rod
cover.
• O-ring is damaged.
• Replace the faulty part(s).
• Backup ring is damaged.
• Replace the faulty part(s).
Oil leaking from welded
joint.
• Tube welding is damaged.
• Replace the faulty part(s).
Spontaneous cylinder
drop (“Spontaneous
drop” is defined as 0.5
mm or greater piston
movement in 10 minutes
when a static load is exert-
ed on the rod. The static
load is determined by
multiplying the maximum
operating pressure by the
cylinder area.)
• Foreign matter is trapped in the wear
ring sliding surface.
• Remove the foreign matter.
• Scratching or abnormality of the wear
ring sliding surface.
• Replace the faulty part(s).
• Scratching on the piston packing slid-
ing surface.
• Replace the faulty part(s).
• O-ring is damaged.
• Replace the faulty part(s).
