What causes the failure of a hydraulic cylinder?
The hydraulic cylinders may incur problems in a long run due to a variety of reasons. This post discusses 7 such reasons for failure of these mechanical devices. Regular equipment inspection, and good preventive maintenance plan will help decrease the chances of cylindrical failure due to the following 7 reasons:
When did the concentric slave cylinder come out?
Since their introduction in light truck applications in the late 1980’s, clutch release systems containing a concentric slave cylinder (CSC) have become the hydraulic system of choice in domestic applications.
Can a side load cause a cylinder to fail?
A common result of side loading is cylinder misalignment, which creates an unusual force on the piston rod. A side load of enough magnitude can result in tube scoring, piston rod and rod bearing wear, and even seal failure.
What do you call a hydraulic throw out cylinder?
This info is to help with the installation and correct setup of a Concentric Slave Cylinder also known as Hydraulic throw out bearings or hydraulic slaves. It is advised that only competent mechanics and technicians attempt to fit CSC’s as incorrect fitting can damage clutch and engine parts.
What causes a bent piston in a hydraulic cylinder?
The cause of damaged rod bearings and bent piston rods is usually improper alignment between the cylinder and the load but can also be caused by loading the hydraulic cylinder beyond the load it is specified for. When the alignment is not correct, there will be a sideways loading or bending induced that the rod bearings are not designed to carry.
What can cause a hydraulic cylinder to fail?
Another major cause of hydraulic cylinder failure is extreme operating temperature — both too cold and too hot. When operating temperatures are too hot, it may lead to premature failure of the seals.
What happens if you Dent a hydraulic cylinder?
Attempts to continue using a cylinder with a dented rod or barrel will cause damage to other components, including bearings and seals. Most instances of excessive wear can be traced back to misalignment of the rod and cylinder.
How is the thrust of a cylinder limited?
The path which the guided load travels must not impose a significant eccentric load on the rod or the piston rod bearing, or the bearing surfaces will be damaged and fluid leakage and reduced bearing life will result. The maximum thrust force which a cylinder should provide is limited by its rod diameter and overall length.
