The World's First -- and Best -- Linear Motion Guides THK's original technology is behind the smooth and silent movement of the "Linear Motion System." The LM Guide is our major product that put the rolling of the linear motion part into practical use for the first time in the world. This improves the accuracy, rigidity, energy saving, velocity, productivity, and service life of the machine. THK offers a full support system from the beginning design phase throughout the maintenance, and follow-up service.

U.S. Navy electrifies aircraft carrier catapult It may be "full steam ahead" for the U.S. Navy's newest aircraft carrier, the USS Gerald R. Ford, but it won't be the catapult that will be steam powered. Less than one week after it was commissioned, the Ford launched and recovered its first fixed-wing aircraft in July using the Navy's new electromagnetic launch system (EMALS) and advanced arresting gear (AAG) system.

Torque sizing criteria for servo motors Servo motors and controllers need torque sensors to operate closed-loop feedback systems. The engineers at FUTEK understand that choosing the right sensor for your system can be complicated, so they've compiled three easy steps in their latest white paper to help you narrow down your search. Read the technical article (PDF).

Engineer's Toolbox: Making an airtight case for freedom -- preserving Lincoln's handwritten draft of Preliminary Emancipation Proclamation Sometimes it's fun to think about how you'd solve a particularly offbeat challenge if given the chance. Case in point is document preservation. President Abraham Lincoln's first handwritten draft of the Preliminary Emancipation Proclamation, a historic document in the collection of the New York State Library and New York State Education Department, will soon be encased in a new high-tech home -- this one custom designed and constructed by NIST. How would you handle the task?

Mike Likes: Optimize mechanical misalignments, get hidden benefits C-Flex Couplings combine the best qualities of disc, beam, and bellows couplings in a unique and economical new design. Made to couple two rotating shafts together, these couplings can accommodate large misalignments while transmitting high torque loads with zero backlash. Benefits include lower energy usage and less-frequent bearing failure, since less stress is placed upon bearings. Constructed using high-strength hardened stainless steel or glass impregnated polyamide flexures, these couplings require no maintenance and provide years of trouble-free life, even in contaminated environments. Flexible Pivot Bearings and Super Plastic Torsional Damping Couplings also available. Watch C-Flex Couplings in action handling misalignments.

Multi-platform exhaust gas recirculation (EGR) coolers To support commercial vehicle manufacturers in meeting current and future emissions regulations, BorgWarner has developed an economical new series of multi-platform exhaust gas recirculation (EGR) coolers featuring a compact floating core. Unlike conventional solutions that must be specifically designed for each application, the company's modular cooler family includes four highly adaptable standard designs for maximum flexibility covering a wide range of engine sizes from 2.0- to 16.0-liter displacement. The new EGR solution offers high robustness against thermal fatigue and enhanced coolant distribution for durable performance even with minimum coolant flow, while reducing NOX emissions.

Direct drive linear motor with integrated encoder The new SDLM-019-070-01-01 direct drive linear motor is the latest addition to the series of zero-backlash, zero-cogging, high-acceleration, high-speed, high-resolution, long-life linear servo motors from Moticont. Also known as an electric cylinder, this compact direct drive linear motor is just 0.75 in. (19.1 mm) in diameter and 2.75 in (69.9 mm) long. Protected inside the motor housing, the linear optical quadrature encoder is directly connected to the shaft for the greatest possible accuracy. This unit has a stroke length of 0.500 in. (12.7 mm), a continuous force rating of 9.7 oz. (2.7 N), and peak force of 30.7 oz (8.5 N). Click here for more information on this product series.

NanoSteel launches 3D-printable tool steel NanoSteel, a leader in nanostructured steel materials, has launched its first product for the laser powder bed fusion additive manufacturing process. BLDRmetal L-40 is a case-hardening steel powder that provides high hardness and ductility (case hardness >70HRC, 10%+ core elongation) and prints easily on standard commercial equipment. This alloy provides superior performance to M300 maraging steel and is an alternative to difficult-to-print tool steels such as H13. Expanding the potential use of 3D printing in a wide variety of hard materials markets, BLDRmetal L-40 is designed to be used for parts including tools, dies, bearings and gears.

Imaging breakthrough reveals magnets' internal patterns Magnets play a vital role in everyday life, are used in everything from hard drives to energy production, and scientists have already been able to study the structure of thin films of magnetic materials. However, imaging the inner structure of thicker forms of magnets has remained an experimental challenge until now.

| Watch High-Speed Ultrasonic XY Motor Align! | |
| This miniature XY linear stage with piezo-ceramic motors combines sub-micron precision with excellent dynamics -- ideal for optics, medical design and photonics applications. In addition to the high speed up to 200 mm/sec, the low inertia (direct drive, no rotating parts) allows for a rapid start-stop behavior with settling times in the milliseconds. How can you use this XY stage?
