 | New Innovative Way to Take Up Tolerances!
Smalley Linear Springs are a continuous wave-formed (marcelled) wire length produced from spring tempered materials. They act as a load-bearing device having approximately the same load/deflection characteristics as a wave spring. Linear Springs are now available as a standard part in carbon and stainless steel, with over 200 sizes.

| | Feature article | NASA bets on bulk metallic glass gears for icy missions
 NASA is developing technologies that will allow exploration of promising places in the solar system ranging from Mars to the icy moon of Jupiter, Europa. These locations have extreme environments that require hardware to withstand temperatures below -150 deg C. Researchers are developing unheated gearboxes to operate in these environments using custom bulk metallic glass (BMG) alloys invented specifically for this application.

 | Wheels: World's fastest truck is Volvo's Iron Knight
Volvo Trucks' 2,400-hp turbodiesel nicknamed the Iron Knight is the world's fastest truck -- twice over. In June it beat the world speed record in the standing-start 500-m (13.71 sec) and 1,000-m (21.29 sec avg over two runs))categories at a closed-off test track in northern Sweden. Top speed was 168 mph (avg over two runs). The 4.5-ton record-breaker that features 6,000 Nm of torque is custom built in every way apart from the engine and the series-manufactured I-Shift Dual Clutch transmission. It has a fiberglass cab and many other weight-saving technologies. The mid-mounted engine is a significantly modified D13 unit with water-cooled intercooler and four turbochargers. The winning records are being reviewed by the FIA, the international motor sport association.

BMW intake system features DuPont Zytel PLUS nylon
An intake system made from DuPont's Zytel PLUS nylon, with its good aging and temperature resistance, fitted with an integrated indirect charge air cooler from MAHLE, helps to optimize fuel/air mixture supply to BMW's new six-cylinder gasoline engines. The innovative structural design of this charge air cooler means it can be arranged in the immediate vicinity of the engine, minimizing bulk and pressure drop and helping to optimize the balance of performance and fuel efficiency.

 | Noteworthy: Compact precision ring drive system optimized for high speed and high torque
The Compact Ring Drive (CRD) system from Nexen Group features a precision-grade bearing and drive mechanism in a sealed housing. Freely programmable, three drive configurations allow the CRD to be optimized for high speed, high torque, or both, depending on the application. The combination of Nexen's roller pinion technology with integrated bearing and motor/gearhead delivers a rigid, smooth system with zero backlash options from the motor through the driven load. The CRD is ideal for applications including cutting systems, gantry systems, medical products, robotics, aerospace, machine tool, semiconductor, and material handling.

 | Springs: Bearing preload series expansion -- smarter solutions for smaller applications
Smalley continues to push the limits in coiling innovation. The expansion of the company's popular bearing preload (SSB) series adds diameters ranging from 9 mm to 13 mm. Now over 300 SSB springs are stocked in carbon and stainless steel, with free samples available to test in your application. The SSB series is a popular choice among engineers, because this single-turn wave spring helps eliminate bearing play and minimize noise. Preloading can reduce the possibility of bearing damage due to vibration (vibratory loading) and wear due to repetitive and non-repetitive runout.

 | Bonding: First instant hybrid cyanoacrylate adhesive
Henkel has introduced Loctite 4090, a versatile, patented hybrid adhesive that combines the bond strength of a structural epoxy with the speed of an instant adhesive. This powerful combo delivers the first structural cyanoacrylate: an adhesive that offers rapid, high-strength bonding to a range of substrates along with impact and moisture resistance, and temperature resistance to 300 F. Versatile enough to solve both indoor and outdoor design and assembly challenges, the new tech greatly expands the capabilities of cyanoacrylates, especially in applications where traditional instant adhesives offer too little strength or are too brittle.
