Top Product: Cross roller ring can swing the loads

Because it has orthogonally arranged cylindrical rollers, the cross roller ring from THK is a roller bearing with high rotation accuracy capable of bearing loads in every direction. Cylindrical rollers are arranged with each roller perpendicular to the adjacent roller, in a 90-deg V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including radial, axial, and moment loads. This component is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments, and IC manufacturing machines. Available in several rotation configurations including inner/outer ring, inner ring only, and outer ring only. And now a new micro cross roller ring is perfect to handle smaller applications.

Solvay develops sustainable Halar ECTFE anti-corrosion coating system

Solvay's new waterborne Halar ECTFE coating system broadens metal corrosion-prevention applications for the chemical processing industry. The coating system is comprised of a high-adhesion primer and topcoat and is easily applied using standard liquid spray equipment. Solvay's Halar ECTFE powder coatings have been used for corrosion prevention for over 40 years for equipment in a range of industries including acids, mining, pulp and paper, pharmaceutical, food and beverage, and semiconductor, among others. The new waterborne Halar ECTFE liquid coating tech expands the range of end-use applications to those that are difficult or impossible to powder coat. This includes complex shapes, uneven surfaces, oversized vessels, pipe interiors, and tanks and containers. Moreover, it provides engineers an alternative protective metal coating option to corrosion-resistant alloys (CRAs).

Lightweight, heavy-duty thermoplastic planks introduced

If you're told to walk the plank these days, you may find yourself walking on plastic. SABIC recently introduced its STADECK heavy-duty panels to the Americas. These high-strength but extremely lightweight panels are used for scaffolding and numerous other applications in the building and construction industries. They are made from glass fiber-reinforced thermoplastic resin and are up to 60 percent lighter than wooden planks, saving not only your back but also the gas or diesel it takes to tote heavier support materials around. They also never rot or corrode.

Plastic torque-limiting wing nuts

JW Winco, a leading supplier of standard industrial machine components, has now made available EN 5320 Plastic Torque Limiting Wing Nuts, which are used when manually applied torque is to be limited. Turn clockwise, and the torque of the wing nut triggers an "over-engagement" when the specified torque is reached. When tightening, this will ensure the maximum permissible torque is not exceeded. Turn counter-clockwise, and the torque needed for loosening will always be transmitted properly. The technopolymer plastic is glass fiber reinforced and temperature resistant up to 176 F (80 C). The wing nuts are available in either a black matte or orange matte finish. An aluminum version (GN 3663) is also available.

Top Tech Tip: Mechanical bellows components are an alternative solution

In today's digital world, mechanical components such as metal bellows serve as an extremely reliable mechanism to gather information. The movement of Servometer® electrodeposited metal bellows under hydraulic or pneumatic pressure (internal and external) can create the information needed for a system w/o electricity. Using bellows technology; temperature, gauge, barometric, and differential pressure can be compensated for. With miniature sizes available, Servometer bellows can be added to instrumentation and manifolds of almost any shape or size.

Alcoa to supply 3D-printed metal parts for Airbus aircraft

Lightweight metals leader Alcoa has entered into an agreement with Airbus to supply 3D-printed titanium fuselage and engine pylon components for Airbus commercial aircraft. Alcoa expects to deliver the first additive manufactured parts to Airbus mid-2016.

Airbus chose to work with Alcoa because of its comprehensive capabilities, from materials science leadership to additive manufacturing and aerospace parts qualification.

Last year, Alcoa acquired RTI International Metals (RTI) -- now known as Alcoa Titanium & Engineered Products (ATEP) -- which grew Alcoa's additive manufacturing capabilities to include 3D-printed titanium and specialty metals parts produced at ATEP's Austin, TX, facility. The Airbus agreement will draw on these capabilities as well as ATEP's titanium ingot melting and billetizing, machining, finishing, and inspection technologies.

The agreement will draw on Alcoa's decades of aerospace experience and new technologies gained through the recent acquisition of RTI and organic expansion in Whitehall, MI.

Alcoa will employ advanced CT scan and Hot Isostatic Pressing (HIP) capabilities at its advanced aerospace facility in Whitehall, MI. HIP is a technology that strengthens the metallic structures of traditional and additive manufactured parts made of titanium and nickel-based superalloys.

Through a $22 million investment in the technology in Whitehall, Alcoa today owns and operates one of the largest aerospace HIP technology complexes in the world.

Additionally, Alcoa is bolstering its additive manufacturing capabilities through a $60 million expansion in advanced 3D-printing materials and processes, including metallic powders. The expansion is located at the Alcoa Technical Center near Pittsburgh, PA, the world's largest light metals research center.
