Keeping Production Running
Cement Backer Board Plant Utilizes Oil Shear Clutch Brake
Navigating Clutch/Brake Operation in Harsh Environmental Conditions: Chemicals, saltwater, food particles, heat, dust, and electrical corrosion are just a few of the many issues that can cause clutches and brakes to fail prematurely.
Deep-Sea Microbe Research
Faulhaber motors help seek climate answers in deep-sea trenches
Experimental Determination of Oil Rheology Parameters to be Implemented in Power Loss Predictions of Gears and Rolling Element Bearings
Rheology models express the way tribological conditions translate to shear stress of the lubricant and friction force on the interacting surfaces. Due to the complexity of the lubricant rheology, the friction coefficient is usually obtained experimentally either under the same operating conditions or by curve fitting in a properly chosen friction map. The current study aims at determining the rheological parameters of a lubricant based on friction measurements carried out on a commercial, readily available ball-on-disc machine.
A New Test Rig to Study Rolling Element Bearing Thermomechanical Behavior
Rolling element bearings are widely used in mechanical transmission to reduce friction between two rotating parts. With the further development of the electrical motor in mechanical industry, REBs operate more and more at high rotational speed. For these applications, REBs power losses can be predominant in mechanical transmissions.
Plugged In (Publishers Page)
At the recently concluded Automate 2019 and Promat trade shows (held in Chicago in April), we saw a lot of new technology aimed at making factories more efficient and productive.
Troubleshooting: Use ALL of Your Senses (Voices)
Troubleshooting infrequent intermittent problems can be one of the most frustrating engineering areas. It is also a great opportunity to use system knowledge and all of your senses and sleuthing abilities.

Hands-Free Driving in the 1950s (Power Play)
Yes, the headline is correct: Autonomous vehicles are not a new idea. In fact, in the 1950s, handsfree driving so interested General Motors engineers that they designed a concept car for it. And in 1956, at its own auto show, the GM Motorama, the automaker unveiled the car, the Firebird II.
