Guide rollers may seem like simple, standard parts, but these rollers with ball bearings are in exceptionally high demand. JW Winco has expanded its guide roller offering to include the standard part GN 753.1. With its entirely new design, these guide rollers have a special deep groove ball bearing of hardened roller bearing steel. They are available in six sizes, from 0.866 to 1.969 in. (22 to 50 mm) outer diameter. The bearing features permanent lubrication and a typical 2Z seal to protect against dust and dirt (in other words, the bearing is covered on both sides by metal disks).

Watch how Bosch Rexroth's VarioFlow plus conveyor system, designed using a stacked configuration, moves products smoothly and quickly within a narrow footprint at the Yamamotoyama of America tea company in Pomona, CA. The facility operates multiple tea bag manufacturing and carton machines, each of which can produce 300 tea bags (which is 18 full cartons of tea bags) per minute. VarioFlow plus is a flexible, modular plastic chain conveyor system used for moving high-volume packaged goods. The solution has been a huge success for the facility, increasing production speed without damaging products.

The way they see it over at Polyclutch, there aren't a whole lot of problems you can't solve with a slip clutch. Way beyond using them for overload protection, there are a surprising number of other applications for these versatile and valuable components. From increasing machine speeds and applying constant tension on wire to indexing a conveyor and automatic screw assembly, slip clutches just may provide the design leverage you've been seeking.

3D Systems has added two new materials to its materials portfolio. Certified HX is a high-performance nickel alloy that contains a higher percentage of molybdenum (up to 9.5%) vs. other nickel alloys, which enhances strength and resistance to corrosion, creep deformation, cracking, and oxidation in hot-zone environments. Certified CuCr2.4 is a high-strength, corrosion-resistant copper alloy that is significantly stronger than pure copper and easier to process. Both materials are certified for use with the company's DMP Flex 350 and DMP Factory 350 3D printers. Applications include industrial gas turbines, consumer goods, aerospace and defense, and automotive.

Plastic injection-molded parts are tough and strong, able to withstand heavy loads, moderately high temperatures, and the corrosive effects of acids and alkalis. In some cases, plastic even competes with metal, and is lighter and usually less expensive to boot. But once in a while plastic needs a little help, like when the bore in an all-plastic pulley quickly wears out or tapped holes in molded handles and knobs get prone to stripping. In these cases, say hello to insert molding.

A new copper coating that kills bacteria quicker and in greater amounts than current formulations could soon be available for hospitals and other high-traffic facilities.
Although current formulations made of pure copper are antibacterial and self-sanitizing, they kill certain types of bacteria with a thicker cell wall (gram-positive bacteria) more slowly than bacteria with a thinner cell wall (gram-negative).
A team of University of British Columbia (UBC) researchers in Canada, led by Dr. Amanda Clifford, an assistant professor in the Department of Materials Engineering, have designed a nano-copper coating that includes bacteria-killing nanoscale features and zinc. The nanoscale features are tiny bumps that can kill bacteria by rupturing their cell wall. Zinc, which is also antibacterial, selectively oxidizes in the presence of copper and helps kill bacteria more quickly compared to pure copper alone.
"Use of our coating could significantly reduce the incidence of contracting bacterial infections from high-touch surfaces in healthcare facilities, such as doorknobs and elevator buttons, since it kills bacteria using multiple approaches," said Clifford. "As it contains less copper than other existing coatings or whole copper parts, it would also be cheaper to make."
The team found that the material took just one hour to kill 99.7% of Staphylococcus aureus -- a gram-positive pathogen commonly responsible for hospital-acquired infections -- compared with two hours for pure copper.
"Not only does this coating kill pathogens faster than pure copper, it helps ensure antibiotics remain effective," said Clifford. "By using this new formulation, we're killing pathogens before patients become infected and need to use antibiotics against them, slowing the rise of antibiotic resistance."
The researchers have filed a provisional patent for the coating and fabrication process, which is described in a new paper in Advanced Materials Interfaces.
"This is currently targeted for hospitals and healthcare settings, because these locations are where the antibiotic-resistant pathogens, such as methicillin-resistant Staphylococcus aureus (MRSA), are an issue. We also don't want to be at a place where we can't use antibiotics," said Clifford.
The team plans to evaluate the material against other pathogens further, such as viruses, with hopes to eventually commercialize their work.
