Servomotor bellows are for dynamic-sealing applications which are restricted by space limitations or where long life and reliability are critical. They can be designed for a variety of stroke and pressure combinations and for temperatures from -423 to 350F. Design manual contains formulas for designing miniature electrodeposited nickel bellows. A list of the 16 bellows available from stock includes data on the spring rate, compression stroke, and pressure rating.

Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
