Uhing Company has introduced the RS4 linear drives. Available in seven sizes, the drives feature shaft rotational speeds of up to 10,000 rpm, travel speeds from 0.5 ft/sec to 4.0 ft/sec, and axial thrust of 22-449 lbs. Specially machined Uhing rolling ring bearings are installed under pressure inside the drives, creating a constant single-point contact between the bearings and the drive shaft and resulting in zero-play without the need for other anti-backlash solution.

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.
