What is Beta Ratio?

Beta Ratio refers to the efficiency in which a given filter element removes particles of a given size. The Beta Ratio is calculated using the ISO multi-pass test standard 16889:1999. The test involves adding particles of a known size to the test fluid until the fluid reaches a saturation point, and then bringing the filter […]

Duo-material seals combine strength and flexibility

Fluid-power engineers who design sealing systems always have to weigh the trade-off of minimizing leaks versus shorter operating life. In hydraulic applications, seals made from two polyurethane components could resolve the conflict between sealing tightness and strength.

What are the top 5 forms of hydraulic contamination?

By Josh Cosford Dirt. That’s what you think of when you hear the term contamination, especially as it relates to hydraulic systems. It is, of course, a common form of contamination. But ingested evils are not limited to the same types that turn your white Yeezys brown. In fact, contamination comes in many forms, some […]

How is sealing used in fluid power systems?

By Josh Cosford Seals are like car tires. They’re both absolutely essential to the operation of their respective accompaniment, yet are unappreciated by most, unless you’re a race car driver or fluid power engineer. And just like tires, seals used in fluid power have changed only by quantum leaps (the real use of the expression, […]

How often should I replace the seals in my cylinders?

There is a lot of variability in how often you should replace your cylinder seals. First, you have to ask yourself some questions. How often are you using the cylinder should be the first question. How fast is the cylinder moving, and do you have high velocity seals installed on it? What’s more, how contamination-free […]

What makes a seal for hydraulics different than a seal for pneumatics?

With seals for pneumatic application uses, one consideration to think about is the severeness of the duty. Obviously, the durometer is very important. When you get into a 70, 80, or 90 durometer seal, it becomes very resistant to being smooshed. As the pressure increases—say 3,000, 4,000, 5,000, or maybe even 10,000 psi or more—it […]

How do you install a fluid power seal?

An important consideration for seals in fluid applications is installation—literally how a cylinder seal is installed, and what you need to know when you’re picking a seal. How we describe a seal is the cross section, which is looking at a seal from the side. The cross section is the width across the U-cups, or […]
