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.

High-force linear motion: How to convert from hydraulic cylinders to electric actuators Electric rod actuators can provide superior performance over hydraulic cylinders in many applications, while also improving efficiency and reducing maintenance. Although the advantages are clear, the process of converting from a hydraulic to an electric actuation system requires close attention to actual force and motion data -- in particular, not over-sizing the actuator.

| Army making 'digital twins' of Black Hawk helicopters | |
 The U.S. Army is turning to "digital-twin" technology to resolve supply-chain and maintenance issues for its enduring fleet of Black Hawk helicopters. The digital twin opens the door to acquire parts that are out of production while building the capacity to use advanced techniques, such as additive manufacturing, to produce components.

The camera that saved Hubble: A look back In December 1993, NASA held its collective breath as seven astronauts on space shuttle Endeavour caught up with the Hubble Space Telescope 353 miles above Earth. Their mission: Fix a devastating flaw in the telescope's primary mirror. April 2020 marked 30 years since the Hubble Space Telescope's launch -- a project that has produced fantastic highs (thousands upon thousands of incredible images) and deeply wounding lows (an instrument that initially did not work as built).

Graphene-reinforced carbon fiber: Cheaper, stronger for car and aero parts Researchers at Penn State have found that adding small amounts of 2D graphene to the expensive process of creating carbon fibers both reduces the production cost and strengthens the fibers markedly. Improving these lightweight, high-strength materials can benefit many different industries, including automotive and aerospace.

Weird, wild, and wonderful: 50 years of Mazda rotary-engine prototypes Founded in 1920, Mazda is celebrating its 100th anniversary this year. As part of the big celebrations, we take a look back at two of the things the company is well known for: its success with the rotary (Wankel) engine, first introduced in the company's vehicles in 1967, and their sometimes-out-there prototype rotary-engine cars, which range from fancy track racers to everyday commuters.

No Drip Spray Nozzles sanitize, clean, and cool EXAIR's new 1/2 NPT No Drip External Mix Air Atomizing Spray Nozzles work in the same way the company's standard atomizing nozzles do, but have the added benefit of positively stopping liquid flow when compressed air is shut off. External Mix Air Atomizing Spray Nozzles have the highest flow rates and allow the air and liquid flow to be adjusted independently. They can be used on liquids above 300 centipoise. The patented No Drip design requires no additional air line to control the No Drip feature.

New Porsche 911 Targa: Better with age It's been 55 years since the Porsche 911 Targa was first introduced as a prototype at the International Motor Show in Frankfurt, Germany, in September 1965. The 2021 380-hp Targa 4 and 444-hp 4S models prove that some things just keep getting better with age -- with a few key tweaks here and there that add to the line's power and refinement. There's also a 911 Targa 4S Heritage Design limited edition in the works, with nods to the brand's racing legacy.

Can scientists make matter only using light? High-power laser simulations aim to help make it happen A new set of simulations by a UC San Diego research team points the way toward making matter from light. The process starts by aiming a high-power laser at a target to generate a magnetic field as strong as that of a neutron star.
