Hydraulic valves, in addition to the force density advantage of actuators, are what help make hydraulics unique in its control of force, torque and motion. Valves govern direction, pressure and flow of hydraulic fluid, enabling smooth, safe and controlled use of actuators. Every machine both requires and uses valves, varying vastly in execution from a […]

The real cost of filtration
Unplanned maintenance, downtime or a need to unexpectedly change a hydraulic filter element is not an option in any underground mining operation. Today, proper hydraulic maintenance has become even more critical because the mining industry is facing the toughest operating environment in its history. Managing both cost and improving system performance are key factors dictating […]
Modular transducer allows measurements up to 130 ft
Position sensing in mobile applications can be tricky, especially on large machines with long boom cylinders. Such machines often rely on cable reels and string pots, but these devices are not always reliable. They can stretch, thus require recalibration. And the elements—winds causing erratic readings and dither in the hydraulics, ice buildup preventing the wire […]
Rexroth expands its GoTo program to all of North America
Bosch Rexroth has expanded its GoTo Focused Delivery Program, with it now being available in the U.S., Canada and Mexico. In addition, the company has added more than 250 new hydraulics components into the program. Earlier this month, Bosch Rexroth highlighted its continued growth in its “local-for-local” manufacturing plans, with the expansion of its Bethlehem, […]

Two series of hydraulic cylinders for NFPA mounting are available from Ortman Fluid Power, Quincy, Ill., for medium- and heavy-duty operation. The 3TH series is a heavy-duty design of tie-rod construction, rated for pressures up to 5,000 psi. They are available in with steel-bodied bores from 1.50 to 20.00 in. bores. Its robust design incorporates […]
Bosch Rexroth continues U.S. growth with Bethlehem, Pa. hydraulics expansion
Bosch Rexroth reiterated its commitment to “local for local” manufacturing this week, as it celebrated the grand opening of its expanded hydraulics facilities in Bethlehem, Pa. Boasting an additional 150,000 square feet, the newest facility brings the number of Bosch Rexroth buildings in the Bethlehem area to seven. Previously, the space at Broadhead Road only […]
Five tips for spring maintenance in your hydraulic systems
By Josh Cosford Spring has arrived, with all the fanfare of a 3675th place finish in the Boston Marathon. As I write this, I am elated by the sunny and relatively balmy weather outside, but also saddened because I know the daytime high barely pushed the mercury into the “normal” range for this time of […]
Trelleborg launches online learning modules on sealing
If there’s one thing the fluid power industry needs, it is as many opportunities for users of its technologies and components to have chances to learn about them. And while more universities are offering fluid power courses and a fair number of companies offer on-site training, there is still room for growth. That’s why I […]
Eaton launches low-temperature hydraulic hose
Last week during IFPE, Eaton Corp.’s, Hydraulics Group, Eden Prairie, Minn., introduced the Ice Champion EC810 hose for extreme low temperature applications. This spiral wire reinforced hydraulic hose withstands temperatures as low as -57°C (-70°F) and pressures as high as 420 bar (6,100 psi) making it particularly well-suited for use in high pressure hydraulic circuits […]
