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?

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 patents stainless-steel flat-face sealing ring for use with tube fittings
Parker Hannifin was recently issued U.S. Patent No. 9,453,600 for a new stainless steel flat face sealing ring for use with tube fittings in extreme temperature applications. The new seal design was developed by engineers at the Parker Tube Fittings Division and is a principal design feature of the Parker Seal-Lok Xtreme line of flat face seal … [Read more...] about Parker patents stainless-steel flat-face sealing ring for use with tube fittings
How can hydraulic lubrication management optimize seal performance?
The concept of lubrication management looks at adjusting the lubrication conditions of all single sealing elements within a sealing system to ensure that the load on each element can be reduced and performance around friction-wear-lifetime can be optimized. Constantly increasing performance requirements for industrial equipment and the … [Read more...] about How can hydraulic lubrication management optimize seal performance?

How do you remove water from hydraulic fluid?
Various types of contamination occur in fluid power systems: gaseous (e.g. air), liquid (e.g. water) and solid contaminants. Focusing on water, this type of contamination can be caused by moisture from ambient air, leakage of cooling systems or process water, leakage of seals and chemical processes such as combustion, oxidation and … [Read more...] about How do you remove water from hydraulic fluid?
Looking toward fluid power and Industry 4.0 at Hannover Fair 2017
There's no doubt about it, Hannover Fair is an enormous industrial trade show—often said to be the world's largest. It's a must-attend event for many companies every year, but for the fluid power industry, the odd-numbered years are especially important. In those years, the Fair includes a particular focus on fluid power and motion control … [Read more...] about Looking toward fluid power and Industry 4.0 at Hannover Fair 2017
When should you use a filter cart?
Filter carts are mobile kidney loop systems that contain a motor, a pump and a filter to form an independent unit. Filter carts can generally be used in two different ways: as enhancement to existing hydraulic system filters, and as fluid preparation for use in hydraulic systems after an event (e.g. replacing fluid, repairs, maintenance, etc.). Dan … [Read more...] about When should you use a filter cart?
What is molecular dynamics simulation of hydraulic fluid?
In a recent blog, “A nanoscale view of hydraulic fluids,” we related how researchers at the University of California, Merced and the Milwaukee School of Engineering are working to better understand the fundamentals of hydraulics fluids on the molecular level, and how that might lead to more-efficient fluid-power systems. A key tool in the … [Read more...] about What is molecular dynamics simulation of hydraulic fluid?
