What they don’t teach you about polymer gears in engineering school
Gears, especially in open gearing applications, share a set of well-known performance problems that crop up again and again across many different applications. The most common ones include excessive noise, vibration, heat, weight and corrosion. Gears also tend to be either over-lubricated or subject to wear, which respectively causes contamination from grease or metal particles. At best, all these performance issues will result in gears that are expensive to maintain. At worst, they will cause gears to fail prematurely, driving costs even higher.
Download our paper to read how you can solve all of these problems with good polymer gear design practices.

NASA's new shape-shifting radiator inspired by origami

A technologist at NASA’s Goddard Space Flight Center has teamed with a couple of researchers at Brigham Young University to advance an unconventional radiator that would fold and unfold, much like the V-groove paper structures created with origami, the art of transforming a flat piece of paper into a finished sculpture. The novel radiator controls the rate of heat loss by performing shape-shifting maneuvers.

Back-blow air nozzle for cleaning tiny inside diameters
EXAIR’s new Model 1004SS, M4 NPT Back-Blow Air Nozzle has been designed to deliver the smallest, most effective airflow for blowing debris and liquids from small pipe or hose inside diameters, channels, bores, holes, internal threads, and other internal part features. An array of holes provides a forceful 360-degree airflow to clear out coolant, chips, and light oils from machining processes. This nozzle prevents blowing chips further into a part, tube, or pipe and eliminates any safety hazard created by blowing debris out the far end of a pipe or tube. Effective on diameters up to 1 in.

IKO offers two lubrication options for cam followers
IKO International now offers two different long-term lubrication technologies for cam followers: a self-lubricating solution for the cam follower itself, as well as an external mechanism that lubricates the bearing surfaces against the rail. IKO’s line of C-Lube cam followers include a thermoset solid lubricant pre-packed into the bearing space for long-lasting, maintenance-free operation. Stud diameters are available from 5 to 20 mm. IKO also offers separate, hood-like units that may be attached to metric cam followers. These supply high-quality lubricating oil to the outside diameter of the cam follower outer ring and track surface, enabling uninterrupted smooth motion on track surfaces for several years.

NASA works to create coolest spot in the universe
This summer, an ice chest-sized box will fly to the International Space Station, where it will create the coolest spot in the universe. Inside that box, lasers, a vacuum chamber, and an electromagnetic "knife" will be used to cancel out the energy of gas particles and freeze gas atoms to a mere billionth of a degree above absolute zero. That's more than 100 million times colder than the depths of space.

FUTEK ultra-mini in-line load cell

Introducing FUTEK's brand new in-line load cell: the LCM100 model. It’s an ultra-miniature threaded load cell that has a capacity range of 1,000 g to 25 lb. RoHS complaint, the load sensor is great for both tension and compression applications. The most impressive feature of the LCM100 is its very low deflection, which allows it to provide high response rates and superior settling times.
See what makes the LCM100 a standout.
