Edited by Mike Santora Most failures in oil systems (up to 80%) are related to oil contamination. Failures like this are a common problem in large industrial applications and mobile machines as well as systems powered by small hydraulic power packs. Effective off-line filtration — continually or temporarily during filling and cyclic service … [Read more...] about Portable filter device for off-line filtration

What is the “toast” test?
An important characteristic of many hydraulic fluids is the ability to maintain performance at high temperatures. Higher temperatures can cause oxidation—the reaction of the fluid and its constituents with oxygen. The rate of reaction accelerates as temperature increases, as does the presence of catalyst metals like copper and iron, especially at … [Read more...] about What is the “toast” test?
Storage and cleaning of elastomer seals
Elastomer seals are built to handle a wide range of demanding hydraulic and pneumatic applications. A seal’s design and its material properties are two keys to lasting performance. The engineers at Parker Hannifin’s Engineered Materials Group in Germany also offer some important recommendations on how to store, handle and clean seals prior to … [Read more...] about Storage and cleaning of elastomer seals

What does hydraulic maintenance mean to you?
By Josh Cosford, Contributing Editor I once had a walk-in customer bring with him an old, rusty spin-on filter, which I believe was originally coloured white below the now orange and brown soup of rust and oil. He needed a replacement filter for his vacuum truck, a machine he said he bought used eight years ago. I grabbed a stock filter head to … [Read more...] about What does hydraulic maintenance mean to you?
Material matters: Understanding wear ring benefits
Wear rings can be an integral part of a hydraulic system, as they absorb side loads and eliminate metal-to-metal contact, extending system life. Contributed by Tom Zozokos, Product Manager, Trelleborg Sealing Solutions Streamwood and Beth Figliulo, Fluid Power Segment Manager, Trelleborg Sealing Solutions Americas Wear rings, whether … [Read more...] about Material matters: Understanding wear ring benefits
IsoLogic connected desiccant breather from Des-Case is first IIoT breather on market
Des-Case Corp. today announced the launch of IsoLogic, the first connected desiccant breather. The patent-pending device is Des-Case’s first entrance into the rapidly growing Industrial Internet of Things (IIoT) space, expanding on the launch of the first desiccant breather by the company in 1983 and its many innovations since. It is projected … [Read more...] about IsoLogic connected desiccant breather from Des-Case is first IIoT breather on market
What functions do hydraulic fluids perform in a system?
Contributed by Carl Dyke, CD Industrial Group Hydraulic fluid is the energy transfer medium in all hydraulic systems. This simple function is only achieved by a fluid that does not easily trap gasses. Trapped gas and foaming problems would bring a higher level of compressibility to a fluid that is usually relied upon to support a very stiff, … [Read more...] about What functions do hydraulic fluids perform in a system?
What types of hydraulic filters are available?
Contributed by Josh Cosford Many fluid power systems fail simply because there is too much particle contamination in the fluid medium. In fact, some estimate that 75% of all fluid power failures can be attributed to contamination-related issues. Thus you, as an engineer, technician or end-user, who ignores filtration does so at the peril of … [Read more...] about What types of hydraulic filters are available?
