THK's newest actuator has 200 percent higher load capacity than the original Type GL, using two caged ball type LM guides (Type SSR and Type SHS), and four raceways, instead of the standard two. It goes up to twice as fast as conventional types (at 5m/sec, and accelerations over 5Gs), due to the lack of metal-to-metal contact, plus tests show noise levels up to 15 dBA lower. It lubricates itself with gaps between rolling elements that retain grease. An aluminum extrusion base makes for a lightweight, strong construction. It comes with metric mounting holes, but inch mounting holes are available for the same price. Ball screw and belt-driven versions are available, the former with a QZ lubricator. They come in standard lengths of up to 3m, with custom lengths available. Accessories include bellows covers and a LaCS Scraper.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
