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

Eliminating a weak-link in hydraulic performance with new hydraulic fluid test
In recent years, operating pressure and power density in many newer hydraulic systems have increased significantly. Not too long ago, pressures in circuits topped out at around 3,000 psi. Now, systems running at 5,000 to 7,000 psi or more aren’t uncommon. On one hand, that can mean better performance, smaller and lighter components and, possibly, … [Read more...] about Eliminating a weak-link in hydraulic performance with new hydraulic fluid test
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
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?
A nanoscale view of hydraulic fluids
There’s a growing realization that the type and formulation of hydraulic fluids can have a significant effect on machine efficiency, performance and overall life. But to date, fluid manufacturers have, for the most part, relied on traditional laboratory methods to develop new fluid chemistries. Now, in the project “Simulation, Rheology and … [Read more...] about A nanoscale view of hydraulic fluids
NFPA Milwaukee Regional Meeting talks to focus on contamination and fluid control
The 2016 NFPA Milwaukee Regional Meeting, scheduled for Tuesday, September 27 at the Milwaukee School of Engineering, will feature two experts from the industry with experience and solid information regarding important challenges that fluid power users may encounter. “The Value of Leak Testing in Preventing Hydraulic Fluid Leaks” will be … [Read more...] about NFPA Milwaukee Regional Meeting talks to focus on contamination and fluid control
How can exclusion seals extend hydraulic motor life?
Few people think of the motor’s exclusion seals as key components in a piece of equipment, but these unsung heroes can make all the difference, particularly in harsh environments. When a motor’s pressure seal is compromised, the machine starts leaking oil into the environment, which immediately impacts your bottom line. Lost productivity and … [Read more...] about How can exclusion seals extend hydraulic motor life?
Why is it important to minimize overheating in your hydraulic system?
By Dave Marlowe, Owner/CEO, DMAR Technical Training and DMAR Business Centers USA In a previous article, I stated that the most important consideration in the selection of a hydraulic fluid was selecting an oil of the right viscosity. I also explained the difference between viscosity and viscosity index. Now we’ll share insights for the operator … [Read more...] about Why is it important to minimize overheating in your hydraulic system?
Trelleborg continues North American expansion with Anderson Seal acquisition
Trelleborg, Fort Wayne, Ind., announced today that through its business area Trelleborg Sealing Solutions, it has signed an agreement and finalized the acquisition of Anderson Seal LLC, a privately owned US-based seal distributor and value-added service partner. According to Linda Muroski, President of Marketing Americas, Anderson Seal was a one … [Read more...] about Trelleborg continues North American expansion with Anderson Seal acquisition
How does a coalescing filter work?
Large contaminants in a pneumatic system are readily captured by general-purpose filters or tend to settle out of a compressed-air stream. Air dryers can effectively remove water from compressed air. But aerosols—extremely small (≥ 0.1 micron) solid particles and liquid droplets of oil and water suspended in the air—remain in the flow stream and … [Read more...] about How does a coalescing filter work?
