MOTION CONTROL: An Ohio-based manufacturer of horse-drawn farming equipment predominately employed by Amish communities uses iglide® plastic plain bearings from igus® on a “crumbler” mechanism; used to crush clods of dirt during the tilling process. The bearings replaced a system of metal shafts and collars that required messy lubricants and frequent maintenance. iglide G300 bearings are used on each of the crumbler’s eight rolling elements. Grease fittings made the rollers susceptible to dirt build-up, which eventually led to the formation of a thick sludge as the tool sat idle between harvests. iglide bearings are lubrication-free and dirt- and dust-resistant. They are also unaffected by rain and any moisture from the soil because of their corrosion-resistant and low-moisture-absorption properties.
iglide plastic plain bearings are available in 28 different polymers. Every iglide bearing material possesses a number of special features, which makes it suitable for particular applications and requirements. iglide G300 bearings are cost-effective and can be paired with a number of different shafting materials. They are best for rotational and oscillating movements and low to average running speeds. They also possess a low coefficient of friction and high wear-resistance.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
