THK World-Class KR Actuators -- Rigid, Accurate and Compact
The LM guide actuator model KR from THK provides high-rigidity, high-precision functionality and space saving. It is achieved by a nut block designed in a structure that integrates an LM rail having a highly rigid U-shaped cross-sectional form with the LM guide section.

The KR features a four-way equal load rating. The LM guide actuator can be operated in any position, which makes it ideal for loading in directions that are not fixed.

Researchers claim big advance in 'massless' structural battery tech
Researchers from Chalmers University of Technology in Sweden have produced a structural battery that performs 10 times better than all previous versions. It contains carbon fiber that serves simultaneously as an electrode, conductor, and load-bearing material. Their latest research breakthrough paves the way for essentially "massless" energy storage in vehicles and other technology, where the battery becomes part of the load-bearing structure.

Design Tips: Fasteners for printed circuit boards
When specifying hardware for printed circuit board applications, many designers may still turn either to loose fasteners or broaching fasteners. While both provide the necessary functionality, each carries potential risks that may impact the production process, the integrity of boards, and even disassembly if required. Leon M. Attarian of PennEngineering runs through profiles of the latest surface-mount fastener families.

Servo-insert coupling with new hub design
RINGFEDER has recently released its GWE 5113 series of elastomer jaw servo-couplings featuring a new hub design. This design eliminates radial loads and achieves uniform power transmission with an even clamp force and symmetrical arrangement of clamp and screw positions. GWE 5113 couplings precisely transmit torques from 3 to 560 Nm. The hub is slit partially through and located directly under the jaws to minimize pressure on the shaft. Backlash-free units come with an elastomer spider with 98 Shore A hardness, minimizing movement and achieving longer life cycles. Seven sizes available.

Autoloader for Army's Extended Range Cannon Artillery tested
Engineers at Picatinny Arsenal are testing an autoloader for the U.S. Army's Extended Range Cannon Artillery that is two to three times faster than a cannon crew. Autoloading could also enhance lethality and may set the stage for future "optionally manned" artillery battery configurations. It's a real engineering challenge, though, getting all the parts to work together.

Videos+: Technologies and inspiration in action
Recommended: New advanced inductive technology unaffected by magnetic fields
This video demonstrates how Novotechnik's new TF1 position sensor enables improved performance for your machine application. TF1 touchless position sensors feature advanced inductive technology. Sensors are highly accurate, robust, and immune to EMI and magnetic filings. Linearity is +/-0.025%, 10-kHz update rate; reproducibility is to 5 micrometers; operates up to 100 g shock and 20 g vibration. This technology is the new standard replacing magnetostrictive for position measurement. Lots more to learn here!

High-performance vibratory feed system handles larger range of parts
The SPIROL Series 2000 is a proven and reliable dual-axis feeding concept that is unlike anything else on the market. It can feed many parts that were once considered not suitable for vibrating feeders, including fuses, tablets, packets, soft rubber parts, fragile parts, and parts that are coated or have a film on them. It is tuned electronically rather than by re-springing, which makes setup and changeover for multiple bowls on one drive a snap. In automated assembly lines, this system offers maximum efficiency, reduced power consumption, and less noise.
