• Designing cylinders for low maintenance
  Adding a backup seal can simplify maintenance for large cylinders. Adding a secondary upper seal significantly extends maintenance intervals for large cylinders. A split retainer permits easy replacement of the external O-ring seal without a major teardown of the cylinder. Hydraulic cylinders...
• Top Trends Impacting Design Engineers, part 1
  are replacing hydraulics in aerospace, automotive, and industrial applications. Hydraulic cylinders have long been the only choice for linear-motion applications involving high forces and speeds. But the latest electromechanical systems may offer another option. One reason for the interest...
• Basics of Design Engineering: Hydraulics New Sealing Systems Take the Heat
  Better materials meet OEM's tougher requirements. Excessive pressures and temperatures, as well as fluid incompatibility, have always spelled trouble for hydraulic cylinder seals. And the problems promise to continue. Tighter emissions regulations for mobile equipment, for instance, are leading...
• Unchained innovation
  bike featured an accumulator that stored energy for uphill climbs. The Purdue row-bike team used a hydraulic cylinder as a linear pump, an improvement in efficiency over rotary hydraulic pumps, and estimated that rowing motion generated about 200 W of power compared with 90 W from pedaling a bike...
• Exclusion Seals
  are most commonly used for scraping elements. For corrosion resistance, they may have cadmium or other platings. Boots are used to keep undesired material from entering the seals of hydraulic cylinders and other fluid-power devices. Motion of the rod relative to the cylinder is absorbed by the flexing...
• Pneumatic linear guides lighten loads
  motors, electromechanical ball-screw or belt drives, and hydraulic cylinders. But designers of automated assembly machines increasingly turn to pneumatic linear guides because they provide a combination of features that enhance overall machine performance. Pneumatic systems require a source...
• Reservoirs
  Many functions in hydraulic systems are provided by reservoirs. First, a reservoir holds the fluid in a convenient spot for the pump inlet. It supplies extra fluid to the circulating system in the event of leakage or cylinder extension. In addition, most reservoirs are called upon to perform...
• Hydraulics aids trash-to-energy conversion
  Rugged system withstands hot, filthy conditions Each boiler uses four top-plate, pumpmotor groups with the motor on top and the pump hanging submersed in the fluid tank.The pumps control flow to cylinders that move grates and feed trash into the boiler. The A10VSO axial-piston pumps pass flow...
• Is water hydraulics in your future?
  and. pressures to 2300 psi,. motors capable of speeds to 4,000 rpm and torques to 100 N-m,. cylinders specially designed for water hydraulic applications,. power units complete with filter, level gage and valves in a variety of sizes to deliver flows 60 gpm, and. a complete range of accessories...
• Concurrent machining kickstarts motorcycle production
  . A hydraulic and pneumatic clamping system permits four simultaneous machining operations on Harley-Davidson motorcycle frames. The four-spindle operation reduces machining time from 11 min to about 3. The F3 pneumatic valve bank controls air cylinders on the bike-frame holding fixture, powers the lube...
