What causes cylinder creep?
What causes cylinder creep?
Hydraulic cylinder drift can be caused by an internal leak in the cylinder across the piston or an external leak. When internal leaks occur, the hydraulic fluid physically moves from one side of the piston to the other, creating an uneven distribution that causes the cylinder to move or “drift.”
Are there any unvented cylinders that are leaking?
The issue of leaking or underperforming unvented cylinders is not something we are faced with on a regular basis, especially as our primary products are copper cylinder which are proven to be more durable than stainless steel cylinders and less susceptible to corrosion.
What should I do if my cylinder is leaking?
Generally, you’ll simply be replacing a seal or an O-ring in the gland or piston. If your rebuild kit provides a diagram for reassembly, consult this for accuracy. Make sure all parts are well lubricated and once you reinstall the cylinder, start up the machine and test for any leaks.
Can a leaking piston seal cause a hydraulic cylinder to drift?
A popular misconception involving hydraulic cylinders is that if the piston seal is leaking, the cylinder will drift. While a leaking piston seal can be the root cause of cylinder drift, the physics involved are often misunderstood.
What can cause a hydraulic cylinder to bypass?
Another cause of cylinder bypass could be internal damage to the seals, piston, barrel or other internal components.
What should I do if my hydraulic cylinder is leaking?
Plug and cap both the hydraulic hoses and/or pipework along with the ports on the cylinder to ensure no oil is spilt in transit. Once both the rod end and base end hydraulic pins have been removed the cylinder can now be removed.

What causes a piston to become hydraulically locked?
In this condition, due to the unequal volume on either side of the piston, fluid pressure equalizes and the cylinder becomes hydraulically locked. Once this occurs, the cylinder can move only if fluid escapes from the cylinder via the rod seal or its ports.
