 | The World's First -- and Best -- Linear Motion Guides
THK's original technology is behind the smooth and silent movement of the "Linear Motion System." The LM Guide is our major product that put the rolling of the linear motion part into practical use for the first time in the world. This improves the accuracy, rigidity, energy saving, velocity, productivity, and service life of the machine. THK offers a full support system from the beginning design phase throughout the maintenance, and follow-up service.

 | Download Photo Etching Precision Parts Guide
This Tech-Etch guide describes how photo etching produces prototype quantities and large production runs of precision parts for many mechanical and electrical applications, without the high cost and long lead times of hard tooling. Custom metal parts from .0005" thick and up are produced with intricate patterns, precise tolerances and burr-free edges, in addition to exact repeatability. By combining photo etching for blanking with inexpensive or universal tooling for forming, Tech-Etch produces complex designs and shapes.

 | NIST delves into what makes memristors tick
In the race to build a computer that mimics the massive computational power of the human brain, researchers are increasingly turning to memristors, which can vary their electrical resistance based on the memory of past activity. Scientists at the National Institute of Standards and Technology (NIST) have now unveiled the long-mysterious inner workings of these semiconductor elements, which can act like the short-term memory of nerve cells.

 | Choosing between brush and brushless DC motors: What are the tradeoffs?
Designing a system that involves motion and performs as intended requires choosing the right motor. The most fundamental decision involves commutation type. In some cases, mechanically commutated brush motors provide the best solution for the budget. In other cases, only brushless DC (BLDC) motors will do. Allied Motion provides a comprehensive review of the technology, along with tips and tricks for choosing the right solution for a given application.

 | 32-mm brushless motor packs massive torque
The FAULHABER 3274 BP4 series packs a punch, yet weights half as much as competitors' motors -- and in a significantly smaller size, too. The 3274 BP4 is overload?resistant and offers longer operational lifetime than conventional DC motors. It withstands harsh ambient conditions and temperatures from -40°C to 125°C.

 | Replace metal parts: KyronMAX outperforms long fiber thermoplastics
Responding to customer demand for a short fiber thermoplastic material that would outperform the mechanical strength of long fiber thermoplastic (LFT) materials, Piper Plastics developed the KyronMAX series of structural thermoplastic compounds, the next generation in injection-moldable metal replacement technology. KyronMAX is based on short fiber technology, so the polymer behaves more like the isotropic nature of metal and eliminates the processing and fiber breakage concerns associated with LFT compounds. The technology enables very complex parts to be molded with unrivaled mechanical performance and consistency -- and often 20 percent lighter and 20 to 50 percent stronger than LFT.

 | Increase bearing life, eliminate noise and vibration
Bearing Preload is the process of adding a sustained axial load, independent of external loads. Properly preloading a bearing can increase its life and eliminate vibration and noise that result from specified clearance, manufacturing precision, and wear. The Smalley Bearing Preload Wave Spring Series is designed with gap or overlap geometry to prevent binding in tight radial spaces. Over 10,000 parts stocked and customs can be made from .157" and 4 mm to 120" and 3000 mm diameters with No-Tooling-Costs™.

 | Carbon composite bellows springs for lightweighting and more
The Carbon Composite Bellows Spring (CCBS) from MW Industries is a system of carbon fiber elements that combine to work as a high-performance, lightweight, and design-flexible compression spring meant to replace conventional coil springs or metallic Belleville disc springs. It offers value through unique dynamic characteristics and unparalleled in-the-field design flexibility. A functional spring is made from several individual elements, paired in sets and joined to make a stack. The spring rate of the stack is determined by the number of elements, the base rate of each element, and their series or parallel orientation in the stack. Applications include motorsports, aerospace, outdoor recreation, general industry, and high-performance activities.
