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.

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.

Ford and U-M researchers team up to fight microbes in new cars and trucks

We can't see them, but we are surrounded by tiny microorganisms that can have undesirable effects on the surfaces around us. In cars and trucks, these microscopic organisms, including mold and mildew, can quickly take hold and spread over a variety of surfaces leading to discoloration, and even unpleasant odors.

"Vehicle cabins are exposed to a wide variety of environmental conditions that can make them microbial breeding grounds," says Cindy Peters, Ford Motor Company technical expert. "Based on growing consumer desire for health and wellness solutions, we decided to take a look at the interiors in Ford vehicles with the goal of creating a cleaner, more aesthetically pleasing environment for our customers."

Market research firm Mintel reports Americans spend approximately $2.3 billion annually on air fresheners, including aerosols, plug-ins, slow-release, and hanger products found dangling from car mirrors.

Many consumers are sensitive to chemicals or simply don't like the artificial scents of many air fresheners, so a solution that proactively reduces the source of odors for the life of the vehicle might be appreciated.

Engineers from the Ford Research and Innovation Center in Dearborn have been collaborating with a team from the University of Michigan (U-M) led by microbial ecologist Dr. Blaise Boles to evaluate the concentration and growth of microbes in vehicles.

Peters and her colleagues collected samples from a variety of company- and employee-owned vehicles. The samples were then cultured and analyzed at a U-M laboratory in Ann Arbor, MI.

The team took swabs from 10 locations in the vehicle interior, including the steering wheel, radio buttons, door handles, window switches, and gear shift knobs. The U-M researchers found significant bacteria growth at most of the test locations, with the highest concentrations on the steering wheel and the area around the cupholders.

"Our findings suggest car interiors are complex ecosystems that house trillions of diverse microorganisms interacting with each other, with humans, and with their environment," says Boles, assistant professor in the U-M Department of Molecular, Cellular, and Developmental Biology. "The long-term goal is to define the microbial ecology of the car interior and to optimize the design of car interiors to promote comfort and environmental sustainability."

"We weren't surprised to find microbial hot spots on the steering wheel, since that is where a driver's hands are most of the time," says Peters. "The console area near the cupholders is a common location for spilled drinks, so it provides an ideal feeding ground for microbes."

Americans also spend more than $1 billion annually on a variety of products, including lotions, wipes, and sprays, to fight microbial growth. Having identified the source of the microbes in the vehicle cabin, Peters and technical leader Mark Nichols went to work with interior coatings supplier Red Spot Paint and additive supplier Sciessent LLC to develop and test coating formulations that could resist and potentially even reverse microbial growth.

The team focused their attention on three commonly used and EPA-approved antimicrobial additives, including silver-ion, ammonium salt, and polyolefin wax with a nano-silver coating. Panels painted with four different formulations were then evaluated back at the U-M lab to assess the growth rates of microorganisms.

The silver-ion additive, sold under the trade name Agion, was easily the most effective. Parts coated with the Agion-infused paint showed clear efficacy compared to the control parts with the current production paint. Agion, based on elemental ions, works by starving, sterilizing, and suffocating the microbes to prevent them from growing and reproducing.

Cars and trucks generally have a much longer life span than most antimicrobial-treated products, and they operate in a wider range of environmental conditions. Drivers expect features to continue working and surfaces to remain intact even after the vehicle has been on the road for many years. Peters and Nichols subjected the specially coated test panels to an accelerated aging process to evaluate their microbe-controlling properties after the equivalent of years of exposure to sun and heat.

Even after simulating many years of use, the Agion-infused coating was still nearly as effective as it was when brand new. The additive also had little impact on the gloss and color change of the surfaces over the test period. Parts with the antimicrobial-treated coating are now undergoing real-world testing in a number of Ford development vehicles, and the coating is being evaluated for potential use in future Ford vehicle programs.

"We can't control everything that contributes to stains and odors in our cars and trucks," says Peters. "But we're doing our part to maintain a pleasant cabin environment for our customers over the long haul."
