The poultry was placed into bins, 10 at a time, and the bins were stacked 10 high. The 10-high pallet-transfer system consisted of a floor-mounted rack-and-pinion drive system with a gerotor motor driving the pinion to move the pallets. The pallets were then shuttled to one of three locations to be off-loaded for final processing.</p></div> <div class="og_rss_groups"></div><p><a href="" target="_blank">read more</a></p> Seals Mon, 16 Dec 2013 17:13:00 +0000 24681 at Respect seals – they’ve earned it <div class="field-deck"> When you consider the cost of all components in a fluid-power system, seals may give you the most bang for your buck. </div> <div class="node-body article-body"><p>Compared to other components in a fluid-power system, the low cost of seals doesn&rsquo;t earn them much respect. However, rod seals perform one of the toughest jobs in a fluid-power system. They must squeeze the piston rod tight enough to prevent pressurized fluid from leaking out of the cylinder. But if they squeeze too hard, they&rsquo;ll wear prematurely and maybe even damage the piston rod surface. Not only that, seals must prevent leakage at high pressure, low pressure, varying temperatures, a wide range of rod speeds, and when systems sit idle for days on end.</p></div> <div class="og_rss_groups"></div><p><a href="" target="_blank">read more</a></p> Seals Mon, 16 Dec 2013 16:34:00 +0000 24621 at The most-powerful seal test bench in the world <div class="node-body article-body"><p>Installed in a specially constructed well, an 18-ton, 260‑kW floating-mount rod seal test bench is located at Trelleborg&rsquo;s research and development center in Stuttgart, Germany. The machine is capable of simulating the patterns of movements and stresses faced by hydraulic rod seals in some of the most-demanding rod-seal applications, such as aircraft landing gear, injection-molding machines, and mining excavators.</p></div> <div class="og_rss_groups"></div><p><a href="" target="_blank">read more</a></p> Seals News Wed, 11 Dec 2013 16:50:00 +0000 24521 at Literature describes sealing products <div class="node-body article-body"><p> Loose-leaf binder contains tabbed sections with information about spring-energized seals (three types), imperial seals (10 types), metric seals (four types), bearings, and back-up rings. </p> <p> <strong>T-LON Products Inc., </strong>888.340.8566, <a href=""><em></em></a></p> </div> <div class="og_rss_groups"></div><p><a href="" target="_blank">read more</a></p> Seals Tue, 10 Sep 2013 16:18:00 +0000 23261 at O-ring face seal, flange adapters <div class="field-byline"> Alexis Coffey </div> <div class="node-body article-body"><p> Stainless-steel O-ring face seal fittings and flange adapters offer high corrosion resistance and sealing in harsh-duty applications.

Street sweepers were in great demand and used heavily to keep debris off the roads that were still passable. It was important to continually sweep nails and sharp objects that would fall<br /> off trash hauling trucks and flatbed trailers.</p> <p> One contractor complained that his sweepers were breaking down frequently due to their hydraulic motor shaft seals failing. The part of the circuit for the brush motors is shown. The motor on the curb side seemed to fail more often than the one on the street side.</p></div> <div class="og_rss_groups"></div><p><a href="" target="_blank">read more</a></p> Seals Fri, 08 Mar 2013 16:33:00 +0000 19652 at Avoid rod wiper leakage <div class="field-byline"> By Jeff Olsen, Application Engineer, Engineered Polymer Systems Div., Parker Hannifin Corp. </div> <div class="field-deck"> Many designers and manufacturers do not realize that cylinder rod leakage can be attributed to a rod wiper that’s too aggressive. </div> <div class="node-body article-body"><p> The sealing package in a hydraulic cylinder is composed of a rod seal, back-up rings, and wiper, all of which must work together to provide leak-free high performance. Dozens of potential causes for rod seal leakage of a hydraulic cylinder exist, including a damaged rod, damaged seal, inadequate rod surface finish, and incorrect gland dimensions. An often overlooked culprit of rod seal leakage is wiper aggressiveness.</p></div> <div class="og_rss_groups"></div><p><a href="" target="_blank">read more</a></p> Cylinders & Actuators Seals Mon, 14 Jan 2013 15:23:00 +0000 18521 at LC-130F Hercules comes out of deep freeze <div class="node-body blog-body"><p> This entry will be a brief departure from my coverage of the Old Timer from Royal Oak.</p> <p> While going through issues of H&amp;P from the late 1980s and early 1990s for this series, I&#39;ve been coming across interesting articles, many of which are still useful today &mdash; despite being more than 20 years old.</p> <p> The article I&#39;m summarizing today was written by former editor Dick Schneider and was originally published in the August 1988 issue.</p> <p> <strong>Seals come out of deep freeze</strong></p></div> <div class="og_rss_groups"><ul class="links"><li class="og_links first last"><a href="/blog/hitch-post">The Hitch Post</a></li> </ul></div><p><a href="" target="_blank">read more</a></p> Aerospace Seals The Hitch Post Sun, 30 Dec 2012 04:42:00 +0000 18311 at
