Composite spherical and journal bearings are for use in hostile environments, particularly where corrosion resistance is important. These bearings feature a spherical outer surface and are constructed of Teflon and polyester fibers woven into a self-lubricating, bondable fabric supported by a filament-wound, fiberglass epoxy shell. The bearings are self-aligning and can take dynamic misalignment, oscillating, and linear motion. The bearings are targeted for use in surgical and optical equipment, especially where corrosive fluids such as blood and saline solution are present.

A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
