There is a lot of variability in how often you have to change seals in a cylinder. You have to ask yourself, how often are you using the cylinder? That’s the first question. How fast is it moving? High velocity seals? How contamination free is your fluid? Ideally, you should never have to change your seals. If your fluid is clean, if you’re … [Read more...] about How often should I replace the seals in my cylinders?

What tools can be used to simulate the sealing efficiency of different seal pipes or different materials?
There are some tests that you can run. If you have some machinery around, for example, you can pressurize both sides of a cylinder to test the effectiveness of a piston seal. Or you can, say for example, pressurize one side of the cylinder with no hose attached to the other port and the rate at which you see fluid leaking across that piston and … [Read more...] about What tools can be used to simulate the sealing efficiency of different seal pipes or different materials?
What is the purpose of hydraulic fluid?
Hydraulic fluid is used in fluid power systems mainly because of its incompressibility or stiffness. This allows it to provide consistent and powerful transmission of energy throughout a hydraulic system, which allows the actuators to complete the work, whether they are linear or rotary motions. The advantage of a fluid’s compressibility ensures a … [Read more...] about What is the purpose of hydraulic fluid?
Types of seals in a hydraulic cylinder
It is important where you put a seal—every part of a cylinder has seals, and they are there for specific reasons. Rod wipers are the ones that are most exposed to the elements in any hydraulic cylinder application. Rod wipers have a groove that pushes it against the rod itself. Any time the cylinder retracts, anything on the rod wants to be scraped … [Read more...] about Types of seals in a hydraulic cylinder
How do you quantify hydraulic fluid cleanliness?
To quantify cleanliness in any fluid power system can’t be condensed into any problem with one solution scenario. Various types of contamination occur in fluid power systems: gaseous (e.g. air), liquid (e.g. water) and solid contaminants (e.g. rust). Solid contamination is subdivided into three groups: extremely hard, hard and soft particles. … [Read more...] about How do you quantify hydraulic fluid cleanliness?

Why is hydraulic fluid compatibility important for seals?
In a fluid power system, fluid compatibility is often discussed with respect to seals. This means, does the chemical composition jibe with the fluid composition? Chemical composition is the composition of the seal itself. What type of rubber, essentially, is it made from? Generations ago, fluid power seals were made of things like leather and … [Read more...] about Why is hydraulic fluid compatibility important for seals?
Hydraulic fluid test matches real-world conditions
Thanks to higher operating pressures, power density in many hydraulic systems has increased significantly in recent years. That can mean higher performance, smaller and lighter components and better efficiency, although it can also increase the susceptibility to wear and premature failures. Newer pumps and motors are built to handle higher loads … [Read more...] about Hydraulic fluid test matches real-world conditions
Portable dryer keeps water out of hydraulic oil
Most fluid-power users understand that particulate contamination in hydraulic oil can markedly degrade the performance and life of mobile and industrial machinery. Perhaps less recognized is that water contamination in the oil can similarly lead to component failure. Water, whether dissolved in the oil, present in an emulsion or as free water, … [Read more...] about Portable dryer keeps water out of hydraulic oil
Parker to acquire filtration company CLARCOR for $4.3 billion
Parker Hannifin Corp., Mayfield Heights, Ohio, and CLARCOR Inc., Franklin, Tenn., announced yesterday that the companies have entered into a definitive agreement under which Parker will acquire CLARCOR for approximately $4.3 billion in cash, including the assumption of net debt. CLARCO, a manufacturer of mobile, industrial and environmental … [Read more...] about Parker to acquire filtration company CLARCOR for $4.3 billion
