Free-Flex(reg) Pivot frictionless, precision cross-spring bearing is for use wherever limited angular rotation bearings are required for angular travel up to ±30 degrees. The bearings require no lubrication or maintenance, are dirt insensitive, and eliminate the inaccuracies of friction, stiction, wear, radical clearances, and backlash. The pivot has a high radial and axial stiffness to maintain repeatability to ±0.000001 inch in one plane of motion, with low hysteresis, center shift, and thermal drift.

A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
