Convert Rotary Motion Into Linear Motion
Lead screws are a common technology used to convert rotary motion into linear motion, and are often used to provide actuation to a set of linear bearings. Plastic lead screws are an excellent alternative to ball screws in many applications where extreme precision (micron level) is not required. They require no external lubricant, which makes them suitable in applications ranging from sensitive lab instruments to packaging machines.

Researchers developing shrink-wrapping spacesuits
Instead of climbing into a bulky, gas-pressurized suit, a future astronaut may don a lightweight, stretchy garment lined with tiny, muscle-like coils that, with power from a power pack, would contract and shrink-wrap the garment around the body. That, at least, is the vision of some MIT researchers.

Basics of motion control:
How feedback encoder devices operate

Feedback is used in closed-loop systems in applications all over the world to control speed and/or position, and it has an important role in keeping equipment operating smoothly and accurately. Feedback is available in a variety of devices as well as models. There are a variety of devices available in the marketplaces that are employed to derive information about the application's speed and/or position, thus controlling and guaranteeing that the process occurs correctly. These include: tachometer, Hall sensors, encoder, and resolver.

Wings:
Structural health monitoring takes a step forward with in-flight sensor tests

Nine commercial aircraft flying regular routes are on the frontier of aviation safety, carrying sensors that monitor their structural health along with their routine maintenance. These flight tests are part of a Federal Aviation Administration (FAA) certification process that will make the sensors widely available to U.S. airlines.

Seal It, Protect It!

A Smalley Laminar Seal is a metallic labyrinth seal consisting of multiple rings in a groove. Sealing an assembly from contamination while withstanding high temperatures and corrosive environments, Laminar rings are produced from metal. The arrangement and orientation of the rings are dictated by the application/severity of the environment.

Motion control components: Flexible bellows couplings
Precision motion control applications require mechanically tight systems, especially between motors, driven loads, and feedback devices, to ensure accurate positioning. FC Series bellows couplings are the standard bellows coupling configuration offered by Servometer with 16 standard sizes ranging in diameter from 0.250 to 1.00 in. FC couplings employ Servometer's patented electrodeposited bellows to offer maximum flexibility, side thrust capability, and angular misalignment, and are an ideal fit for most motion control instruments including encoders, potentiometers, servomotors, and more. Samples are available.
