Noise is often inevitable in hydraulic systems, but discovering its sources can help you to better design your systems to alleviate some of it. Monday morning traffic, lineups at the Krispy Kreme drive-through, and teenagers; all crap we just put up with every day with nary more than a shrug. I’m officially adding noisy hydraulics…

Combining air and oil on modern automation machinery helps to balance force, speed, precision, reliability, and cost. I know what you’re thinking – “forget it, just use electronic components for automation instead of hydraulics or pneumatics.” Well, you can put the brakes on that idea, fella, because this is Fluid Power World, and I pushed…

Many of you reading this are into cars, and I know this because I know hydraulic people — you like to modify and tinker using old-fashioned elbow grease while working on old-fashioned cars (sorry, your ’90 Civic is a classic, too, old man). A popular trend in classic car circles is the “RestoMod.” You take…

By Josh Cosford, Contributing Editor Hydraulic motors are powerful and energetically dense rotary actuators with designs as versatile as their applications. As a hydraulic designer, you should know how to select a hydraulic motor that best suits your machine, balancing performance, price, and reliability. The range of options is vast, but this guide will steer…

As an engineer, hydraulic specialist or budding designer, knowledge of the various hydraulic pump options is imperative to provide your company or customers with the best possible option for any given machine. Despite personal preference for each pump type, dismissing any given design can potentially reduce system effectiveness or result in excessive costs. A gear…

Electrohydrostatics has evolved over the last four decades from its beginnings in aviation to uses throughout more industrial applications. Contributed by Bill Perry, Managing Partner, MARCH 24 Media LLC, on behalf of Moog Inc. In the 1980s, aircraft manufacturers began exploring ways to eliminate the potential leaks from hydraulic lines and gain efficiency in energy…

With new components, systems, and architectures, hydraulic system efficiency can be increased by 50%, with a one-third reduction in emissions as well. By Alessandro Carmona, President, Industrial division, Danfoss Power Solutions The much-scolded aviation sector produced nearly 950 Mt of carbon dioxide emissions in 2023, according to the International Energy Agency. Meanwhile, a paper to be presented…

Zero-Max has introduced its latest ETP shaft locking devices. The keyless bushings use a self-contained hydraulic system for mounting hubs to shafts and are intended as an alternative to mechanical wedge-style locking devices in motion systems. Precise rotational and linear positioning for ETP shaft locking devices Zero-Max’s ETP keyless locking devices are designed for phasing […]

Design World’s annual LEAP Awards winners were recognized yesterday in a special video broadcast. Two components were recognized in the Fluid Power category, and four other hydraulic technologies were awarded across several other categories. Taking the gold this year was Danfoss Power Solution’s X1P open circuit pump. Built on the all new X1 Platform, it…

Nearly three decades ago Peter Achten, CEO of Innas BV, had the idea for a hydraulic transformer but the concept didn’t take off because hydraulic pumps of the day could not work with the technology. The concept has now gained real traction with the development of the Innas’ floating cup displacement principle, which now serves…

Though hydrogen has proven its value as a sustainable fuel, it remains cost-prohibitive due to the lagging infrastructure necessary for widespread adoption. Common culprits are not the fuel cells or vehicles, but the transportation and operational equipment — especially the critical technologies for hydrogen compression and decompression. “Operational expenses are really bad, and that changes…

Moog Inc., a global designer and manufacturer of precision motion and fluid control systems, announced the launch of its AXP Axial Piston Pump Series, a hydraulic solution for industrial applications.
