New EC-i 52XL 200 W high-torque, brushless servomotor from Maxon
The motor is designed for applications where space is limited but high torque and dynamics are required.
Study: Centrifugal-flow heart pump improves patient outcomes
A two-year trial documented a reduced incidence of pump thrombosis associated with a new centrifugal-flow left-ventricular assist device.
Helios Gear Products introduces Hera 90 CNC gear hobbing machine
Key features include an 8.5 diametral pitch (DP) (3 mn) rating, 6,000 revolutions per minute (rpm) maximum hob speed and up to 8 CNC axes.
New solutions save time and money
Using MC cable and Remke Connectors can mean savings of up to 50% on installation costs.
Yaskawa helps saw manufacturer solve a knotty problem
Yaskawa servos help cut imperfection out of a board in the blink of an eye.
Video: Acoustic metamaterial promises a quieter world
The 3D printed material is configured to block 94% of sound without blocking air passage.
How does a non-spreading line blind help you?
Learn the major advantages of using a Strahman Non-Spreading Line Blind over a traditional spectacle blind.
Jammed flight control led to aborted takeoff, accident report finds
High winds caused an elevator control to jam, preventing the aircraft from rotating as it rolled for takeoff.
Emerson adds three new models to Copeland Scroll KA compressor lineup
The models are designed for low- and extended medium-temperature refrigeration applications.
Elastomer seals – How to avoid the trade-off between purity, plasma resistance, and high temperature performance
Perlast Helios is composed of the new FFKM material family, which offers excellent sealing performance at high temperatures without affecting other key material properties.
Advanced motion control meets open source
Due to several factors related to mass manufacturing and the open-source movement, stepper and servomotors have dropped in price, and novel control solutions that integrate open-source architectures are coming online.
Black oxide finish for extended service life steel bearing components
A German bearing manufacturer is now supplying bearings with a black oxide finish for increased performance in wind turbine gearboxes and other critical applications.
Gas connection error led to fatal house explosion, NTSB says
Central to the NTSB investigation was the installation of a tapping tee, the connection between the gas main and the home’s individual gas line.
Understanding ceramic pumps and pump materials
Ceramic pump materials provide enhanced performance, low wear, high-temperature capability, corrosion resistance and low media contamination.
New diaphragm valve for drinking water applications
The peroxide- and sulfur-free elastomer diaphragms of the new valve are designed for continuous operating temperatures of 90° C.
Easy, quick sand casting of complex auto engine components
A new process produces high-quality, highly robust engine blocks that can be cast in comparatively short cycle times.
Lee Plug expansion plugs
Lee Plug expansion plugs seal fluid passages without the use of O-rings, threads or sealants.
Decoding bearing numbers
At first glance, the series of numbers and letters in a bearing part number can look confusing. But if you have the decoder, it’s relatively easy to understand.
Translating imperial units to metric sizes in O-rings
Converting O-ring dimensions from metric to Imperial units, or vice-versa, isn't an obstacle if an engineer knows the conversions involved.
Bearing tolerances explained
Bearing tolerances are an important concept for design engineers to understand. The American Bearing Manufacturers Association (ABMA) developed the ABEC tolerance standards for bearing manufacturers to follow when producing radial ball bearings.
