At Hannover Messe this week, Bosch Rexroth announced that it has developed a scalable portfolio of servohydraulic drives for compressors in the power range between 10 and 280 kW in partnership with others from the hydrogen industry. Hydrogen produced from renewable energies plays a key role in achieving global climate targets. It is a CO2-free […]

Will AI soon predict internal cylinder leakage?
Electrohydraulic actuators are standalone, self-contained systems that perform powerful tasks without external piping. They typically include an electric servomotor driving a hydraulic pump — often an axial-piston unit. Other components include a hydraulic cylinder, tank, valving and charging circuits. Because they are fitted with their own closed fluid circuit, they require only a small amount […]
Duplomatic MS expands in Germany with mobile cylinder-maker Phillip Acon Hydraulik
Duplomatic MS Spa, a company within the Daikin Group, is pleased to announce a significant development in Germany. Günther Till GmbH & Co. KG, a well-known German cylinder manufacturer and already a part of Duplomatic MS since December 2021, has successfully signed an agreement to transfer the assets of Phillip Acon Hydraulik GmbH, a branch […]
Indispensable hydraulics: making light work in waste & recycling
Waste and recycling applications are dominated by hydraulic technologies, where the power density, ruggedness, speed and precision they provide are crucial to uptime. By Josh Cosford, Contributing Editor Hydraulics have proven to be a versatile and efficient technology in various industries, offering precise control, reliability, and extraordinary power density. Some industries are lightly equipped with […]
Is it necessary to push hydraulics past 10,000 psi?
By Josh Cosford, Contributing Editor Moore’s Law states that the number of transistors in a microchip doubles every two years, increasing computing power exponentially over time. It seems no other technology experiences such a rapid progression, especially considering how relatively young the semiconductor industry is. Fluid power provides us with no such rate of performance […]
Liebherr’s hybrid cylinders for lightweight construction
Lightweight construction is considered an important trend and driver as OEMs strive to make off-road machinery more efficient and productive. It’s also becoming more significant in many stationary applications. In mobile equipment, for example, weight savings can increase operating speeds, allow for larger attachments and booms, and raise payloads. And, of course, it often reduces […]
Hydraulic cylinders staying tough and getting smart
By Josh Cosford, Contributing Editor Technological advancement is accelerating at an exponential pace. Consider only fifty years ago how hydraulic cylinders were constructed much the same as they are today, yet how much has electronic, information and digital technology surpassed our venerable actuators? Hydraulic cylinders are simple and effective. They are so effective, in fact, […]
Force measurement within hydraulic cylinders
Classic hydraulic cylinders equipped with force-sensing elements allow precise and dynamic measurement of static and dynamic tensile and compressive loads. Indirect force-measurement via strain offers a smart alternative, according to engineers at Liebherr Components, Nussbaumen, Switzerland. Increasingly, mobile and industrial equipment manufacturers are focusing on sensor solutions and their efficient use in hydraulic cylinders. One […]
Novel tunnel-boring machine takes on mining with the help of hydraulics
Hydraulically powered unit is the first to cut rectangular tunnels in hard rock. Circular, full-face tunnel boring machines (TBMs) are well-engineered, proven pieces of equipment, and they’re considered the most efficient machines for mechanical excavation of tunnels in rock. But they are not often used in underground mining. That’s because mines generally require a flat […]
Swing-axle cylinders combine travel comfort with rigid work platform
Mobile machines have to meet widely differing requirements. To get to a job site, they need good off-road capability. While they are working, however, high rigidity and stability are essential. Add to that are increasingly demanding safety and environmental regulations. Swing-axle cylinders are built to fulfill all these requirements. According to engineers at Bucher Hydraulics, […]
