Top Tech Tip: Bearing insulation prevents electrical current damage
Bearing damage can occur when electrical currents use the rolling contact as a conducting path. Insulated bearings prevent premature bearing failures eventually caused by stray electrical currents. But insulation properties must remain stable regardless of environmental conditions, in particular when bearings are stored, handled, and operated in humid climates. SKF dives deep into this issue.

Smart Sensor checks condition of bearings
ABB has launched the ABB Ability Smart Sensor for Dodge mounted bearings, part of the ABB Ability Digital Powertrain, that enables "health checks" for bearings. The smart sensor technology provides an early indicator of any potential problems by assessing the condition of bearings from vibration and temperature information. Eighty percent of bearing failures are lubrication related, and a bearing "running hot" can indicate that proper lubrication procedures are not in place. Monitoring a bearing's vibration can also indicate potential system problems. Prevent downtime on applications such as bulk material-handling conveyors as well as applications in the food-and-beverage and air-handling sectors.

SPIROL offers pre-stacked disc springs
SPIROL traditionally supplied Disc Springs solely in bulk packaging, and it was the customer's responsibility to stack the Disc Springs into the prescribed configurations. Those days are gone. SPIROL now offers pre-stacked Disc Springs (greased or ungreased) in custom configurations packaged in shrink wrap with a perforated tab for ease of insertion into the application. The pre-stacked Discs are delivered intact to the assembly line, where the operator simply has to place the stack into the assembly and remove the shrink wrap. Applications include braking systems, pipe supports, pick-off spindles in CNC screw machines, and much more.
Cool Tools: World's darkest spray paint
A whole range of products can now take advantage of the world's blackest coating, Vantablack, thanks to the development of a new spray version called Vantablack S-VIS. It is easily applied at large scale to virtually any surface. Vantablack's carbon nanotube matrix structure absorbs virtually all (99.8 percent) incident light, enabling precision optical systems to be optimized. The material's developer, UK-based Surrey NanoSystems, has mimicked the performance of its original Vantablack with this new version that can be sprayed onto objects, rather than deposited using a chemical vapor deposition (CVD) process.

Research raises awareness of indoor air quality risk from 3D printers

Consumer-oriented 3D printers showed up on many holiday wish lists last year, but purchasers should be aware of research conducted at Georgia Institute of Technology that highlights how the popular low-cost devices could pose a health risk by harming indoor air quality.
A recently completed multi-year research project, sponsored by UL Chemical Safety, was aimed at characterizing particle emissions by the printers in a controlled environment.
The researchers found that the printers generate a range of different-sized particles, including ultrafine particles (UFPs), which have the potential to be inhaled deep into the human pulmonary system and impact respiratory health.
"These printers tend to produce particles that are very small, especially at the beginning of the print process, and in an environment without good ventilation, they could significantly reduce indoor air quality," said Rodney Weber, a professor in Georgia Tech's School of Earth & Atmospheric Sciences who led the research.
Many of the findings were published in 2018 and 2017 in Aerosol Science and Technology, and other studies are forthcoming.
The research endeavor revealed that more than 200 different volatile organic compounds (VOCs), many of which are known or suspected irritants and carcinogens, are released while 3D printers are in operation.
Several factors (including nozzle temperature, filament type, filament and printer brand, and filament color) affected emissions. Meanwhile, extrusion temperature, filament material, and filament brand were found to have the greatest impact on emission levels.
"We found that one of the overriding principles is the temperature of the filament," Weber said. "If you use a filament that requires a higher temperature to melt, such as ABS plastic, you produce more particles than PLA plastic filaments, which require lower temperatures."

As a result of the research, UL is advocating for a complete risk assessment of all 3D printers, taking into account dose and personal sensitivity considerations as well as the publication of more marketplace information about each printer to help consumers choose safer options.
"Following our series of studies -- the most extensive to date on 3D-printer emissions -- we are recommending additional investments in scientific research, product advancement to minimize emissions, and increased user awareness so that safety measures can be taken," said Marilyn Black, vice president and senior technical advisor at UL.
In the meantime, some measures can be taken by operators of 3D printers to lessen their impact on air quality:
- Operating 3D printers only in well-ventilated areas;
- Setting the nozzle temperature at the lower end of the suggested temperature range for filament materials;
- Standing away from operating machines; and
- Using machines and filaments that have been tested and verified to have low emissions.
Based on the scientific research conducted with Georgia Tech and further collaboration with other stakeholders, UL developed an ANSI consensus standard for testing and evaluating 3D-printer emissions to set emissions targets for 3D-printer manufacturers. UL/ANSI 2904 is in the final stages of completion and should be available in the coming weeks.
