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 […]
Systems solutions is the theme at IFPE 2014
When I attended my first IFPE back in 2011, I really had no idea what to expect. But three years makes a big difference and I came in excited and ready to go. And after several successful meetings and booth tours, I think it’s safe to say that the theme from many of the manufacturers […]
Maintaining reliability with hydraulic filters
By Josh Cosford Fluid conditioning is the top priority for those intending to keep their hydraulic machines happy and reliable. Control of the various forms of fluid contamination ensures components will run within their design criteria efficiently and dependably. Major forms of fluid contamination include water, air, heat and particle. Particle contamination is often highest […]
Low-speed, high-torque motor for stationary applications
Eaton Corp., Eden Prairie, Minn., will highlight its latest hydraulic motor technology at its IFPE booth 80230 March 4-8, with the launch of Hydre-MAC,a low-speed, high torque (LSHT) direct drive, radial piston motor. Featuring a cam lobe design—which is a unique design for this type of motor—it is designed for variable speed applications that uses […]
Hydraulic fittings and flanges in mobile equipment
By Josh Cosford Few, if any, fluid power applications would exist without a method to join the “non-standardized standards” of the plumbing requirements of the components in a system. Like an evolved species of the same genus, separated through generations and geography, the long-lost cousins constituting the fittings family tree are as varied as any […]
Hydraulic motors for mobile equipment
By Josh Cosford Hydraulic motors are used in any application where the output of mechanical rotational energy is required, such as augers, wheel drives, fans, mixers, and grinders. Their execution is just as varied as their application, coming in motor types such as orbital, vane, gear and the major piston types—bent-axis, radial and axial. Motors […]
Compact cartridge valves help meet Tier 4 engine standards
With the introduction of Tier 4 engine emissions standards, the conventional wisdom of bigger meaning better has been jettisoned. As OEMs find themselves having to make more efficient use of their available horsepower, the demand has grown for compact and “tune-able” control options. To give system designers a superior level of control with less pump […]
Measuring pressure with transducers
The measurement of pressure had once been a monopoly of Bourdon tube pressure gauges, and if you wanted to check the pressure at any location in a fluid power circuit, you had to go right to the source to install a pressure gauge at the location you wished to measure. The invention of test points […]
