Edited by Alan Hitchcox PTAM20 Positilt inclinometers come in single- or dual-axis versions and use MEMS technology for compact (14 high; <2-in. diameter) size. Measurement range for single-axis version ranges from ±15° to ±180°. Dual-axis ...
Open-circuit piston pumps
Edited by Alan Hitchcox A hydromechanical torque control option has been added to 420 open-circuit piston pumps. They automatically sense heavy loads and adjust hydraulic flow accordingly. Redesigned pump housing decreases airborne noise to ...
Taking the pressure under two miles of water
Maintaining a gas precharge in accumulators operating under 5000 ft of water posed a challenge for operators of offshore oil rigs. A solution to meet this challenge is a new line of bladder accumulators rated for 10,000 psi ...
Heat exchangers
Mobile MA heat exchangers feature brazed aluminum P-bar plate and bar core technology engineered with an aggressive turbulator that produces high heat transfer for flow rates from 2 to 150 gpm. Rated to 250 psi at ...
Hydraulics deserves a gold medal
You may have heard how hydraulics was blamed for a mishap in the opening ceremonies of the 2010 Winter Olympics in Vancouver. Four pillars were supposed to extend from the floor and converge at a center cauldron. Four Canadian celebrities were then ...
Single ferrule fittings
Edited by Alan Hitchcox Brass and 316 stainless steel single-ferrule fittings are available in sizes from 116 to 2 in. Their design makes incorrect installation difficult because of fewer pieces than with other types of fittings. ...
ISO air cylinders
Edited by Alan Hitchcox ISO 6431 compliant air cylinders have adjustable air cushions at both ends and magnetic pistons in seven bore sizes from 32 to 125mm, with strokes to 1000 mm. Machined male rod thread with jam nut also standard. Extruded ...
Smart cylinders maintain the gap
Make hay while the sun shines is an old saying still in use, but it’s literal application became somewhat obsolete when lights on tractors and other farm equipment became commonplace. As with any modern process, making hay ...
Hydraulic Integrated Circuits Provide Big Payoffs
Save space and weight, reduce leakage, boost reliability, simplify troubleshooting, and lower costs — all by specifying hydraulic integrated circuits.
Mini components operate jumbo jet
To save weight on the A380 superjumbo aircraft, resourceful software helped design an innovative decentralized hydraulic system with lightweight micropumps delivering power locally to emergency braking and landing gear steering systems.
More about pressure compensated flow control
By Jack L. Johnson, P.E. Select figure to enlarge. Continuing our discussion of pressure compensated flow control, consider that the evolution of controls for mobile hydraulic machines has always placed levers and foot pedals at ...
Rock drill demands power, speed, and precision
KG Mekaniska’s CT series rock drills use remote control and CANbus communication for sophisticated, yet easy-to-use control.
International conference focuses on fluid power technology
The 7th International Fluid Power Conference (IFK) will be held at the Technical University in Aachen, Germany March 22-24, 2010.
Direct drive from hydraulic motors keeps sweeper design simple
Simpler is better in many cases. Lighter, more compact, and more efficient is better still — especially when you can get it all in one package. Nilfisk’s Model 1302 sweeper uses a pair of radial-piston ...
