In a nutshell, hydraulic cylinders are mechanical components
that provide force in one direction through a stroke. These cylinders are used
in a wide variety of industrial applications and can have issues in the long
run due to a number of reasons. Here are just a few reasons for hydraulic
Piston rod scored
The scoring of the piston rod is commonly caused by oil
contamination. If this has happened to your cylinder you should keep an eye out
for any further contamination, such as to the gland bearing. This can result in
gland bearing failure if it’s not properly taken care of.
This is a common issue that often results in the failure of
a hydraulic cylinder. Seal leakage often occurs due to incorrect fitting of the
seal or corrosion of the seal grooves.
Water in the oil is the most common reason for the barrel
corroding internally. The best way for you to reduce the chance of cylinder
failure at this point is to change the oil.
A lot of the time, hydraulic cylinder failure can be caused
by chemicals coming into contact with the cylinder seal. This can be avoided by
discussing the likelihood of chemical attacks with your hydraulic manufacturer
so you can get an idea for what your cylinder seal can withstand.
Bent Piston Rod
This issue most commonly occurs when the hydraulic cylinder
is being overloaded. This can happen perhaps from some sort of collision or
using the system outside of its agreed specification.
Oil contamination is the main issue associated with
hydraulic cylinder failure. Contaminated fluid can bring severe damage to the
piston rod, seal surface and/or the cylinder bore. The single best way you can
avoid hydraulic cylinder failure is regularly checking your oil for any
