When should designers use crossed roller bearings?

Crossed rollers use a series of cylindrical bearings or rollers set at 90 degrees to one another to form a V that fits into a slot on the rail. Each roller provides an entire line of contact, as opposed to just the point or two of contact provided by liner actuators using ball bearings. The result is less deformation and the ability to carry heavier loads.

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.

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.

Antibacterial handles stop germs in their tracks

Contact infections with viruses, fungi, and bacteria were already a problem even before the pandemic, and now JW Winco is expanding its Sanline range of antibacterial products. For their plastic products, special additives with silver ions are mixed in, while metal parts are given powder coatings based on zinc molybdate.

New metal 3D-printing materials include Inconel, titanium, and maraging steel at Xometry

Xometry has added four new 3D-printed metals to its on-demand manufacturing services: maraging steel, Inconel 625, Inconel 718, and titanium. These premium alloys complement the already available stainless steel and aluminum metal 3D printing. Metal parts in these alloys are produced using direct metal laser sintering (DMLS), which fuses powdered metal with a high-powered laser to build parts layer by layer.
Learn all about these materials in this Xometry blog.


Eaton launches next-gen hollow-head valves for improved engine efficiency

Eaton's Vehicle Group has introduced its next-generation sodium-filled hollow-head valves. Unlike traditional hollow valves, the head portion of the new valves is composed of two separate sections that are welded together during the production process. The new valves have the capability to cool down the combustion face and, therefore, the chamber temperature, which increases the spark advance and air-to-fuel ratio because the engine is less inclined to knock. As a result, the brake specific fuel consumption (BSFC) can be increased and emissions reduced. The valves are being evaluated by several global automakers, with start of production scheduled for 2023.

Counterbalance support hinge for heavy panels and lids

SOUTHCO has expanded its series of Counter-balance Hinges with a new product that reduces the total solution cost of lifting and positioning heavy panels and lids. The CB Counterbalance Support Hinge enables ergonomic lifting and position control when combined with a CB Counterbalance Hinge by using stored energy to balance the weight distribution of a lid or panel. The all-aluminum hinges are fully adjustable, allowing the experience of opening and closing the panel to be tailored to the unique requirements of the application.

Precision flexible antivibration couplings

New Antivibration Flexible Couplings from Stock Drive Products / Sterling Instrument (SDP/SI) are designed for use with high-gain servomotors. When a servomotor drives a mechanism, as in applications such as semiconductor manufacturing equipment, blood analyzers, or high-speed printers, a change in direction causes a phenomenon called hunting. Hunting is vibration in the system that reduces transit time, making the equipment less efficient. The Antivibration Flexible Coupling features a unique construction of vibration-reducing rubber (FKM) molded with aluminum hubs. The resulting rubber-lined, finger-like structure allows for optimal torsional rigidity and damping.

Toughened NASA low-outgassing epoxy

Master Bond Supreme 70CN is a two-part epoxy adhesive formulated using a natural, renewable, and sustainable ingredient. This moderate-viscosity, unfilled epoxy is black in color and can be used for bonding, sealing, coating, and potting in aerospace, electric vehicle, electronic, opto-electronic, battery, and OEM applications, particularly those involving composites and fibers. It resists thermal cycling and is ideal for bonding dissimilar substrates including metals, ceramics, many rubbers, plastic materials, and composites. It features low shrinkage upon cure, a high tensile strength, is serviceable from -100 to 400 F, and has a working life of 60 to 90 min.

U. of New Hampshire Marine School is sending robotic mapping boat to help search for clues to Amelia Earhart mystery

Researchers from the University of New Hampshire's Marine School are part of the crew, led by National Geographic Explorer-at-Large Robert Ballard, that is setting out to hopefully find answers to questions around the disappearance of famed pilot Amelia Earhart.

UNH's Center for Coastal and Ocean Mapping has developed an autonomous surface vehicle (ASV), or robot, that can explore the seafloor in waters that may be too deep for divers.

The UNH robot known as BEN, the Bathymetric Explorer and Navigator, provides Ballard and the crew aboard the EV Nautilus with a unique capability to map the seafloor in the shallow areas adjacent to the island where Earhart sent her last radio transmission. This area is too deep for divers and too shallow for safe navigation of the Nautilus to use its deep-water sonar systems. Maps of the ocean floor produced by BEN will be used by the Nautilus crew to target dives with remotely operated vehicles (ROV) in the search for remnants of the plane.

Evidence suggests Amelia Earhart made a successful landing, likely near the coral reef around the island of Nikumaroro, in the western Pacific Ocean, and was able to transmit radio signals afterward. However, no plane was seen by Navy pilots surveying the islands several days after her disappearance, suggesting that the plane may have been pushed off the reef into deeper water.

BEN is equipped with state-of-the-art seafloor mapping systems including a Kongsberg EM2040P multibeam echo-sounder and Applanix POS/MV navigation system, which allow it to make 3D topographic and acoustic backscatter maps of the seafloor. The Center has developed mission planning and "back-seat-driver" control software designed specifically for piloting BEN for the seafloor mapping mission. BEN was manufactured by ASV Global, in a design collaboration with UNH.

The UNH crew consists of research engineers Val Schmidt, lead of this operation, KG Fairbarn, and Andy McLeod, who are all aboard the EV Nautilus as well as Roland Arsenault, who is supporting the crew from shore. All are a part of the UNH Marine School's Center for Coastal and Ocean Mapping development and use of robotics for marine science and seafloor mapping.

The expedition, which is being covered on nationalgeographic.com, will be featured in a two-hour special titled "EXPEDITION AMELIA" that will premiere Oct. 20 on National Geographic.
