 | Ford F-150 Lightning SuperTruck is #1 at Pikes Peak
The all-electric Ford Performance F-150 Lightning SuperTruck made the fastest pass of all 61 competitors at the 102nd running of the Pikes Peak International Hill Climb on June 23, 2024. Competitors only get one run in the 12.42-mile uphill Race to the Clouds. The SuperTruck victory was hard-earned by driver Romain Dumas after experiencing a technical issue on the course.

 | UVA team makes NASA hypersonic breakthrough
What if the future of space travel were to look less like a rocket and more like a hypersonic jet plane? The world is a step closer since researchers in Virginia showed, for the first time, that airflow in supersonic combusting jet engines can be controlled by an optical sensor. The finding could lead to more efficient stabilization of hypersonic jet aircraft.

 | Engineer's Toolbox: How to pin a shaft and hub assembly properly
One of the primary benefits of using a coiled spring pin to affix a hub or gear to a shaft is the coiled pin's ability to prevent hole damage. Another is the coiled pin absorbs wider hole tolerances than any other press-fit pin. This translates to lower total manufacturing costs of the assembly. However, there are a few design guidelines that must be adhered to in order to achieve the maximum strength of the pinned system and prevent damage to the assembly.

 | Bellows and disc couplings with higher torque capacity
Ruland Manufacturing now offers bellows and double disc couplings with bore sizes up to 1-3/4 in. or 45 mm for use in systems with torque up to 1,400 in.-lb (158 Nm). High-torque applications in precision semiconductor, solar, conveyor, and factory automation applications often use these shaft sizes. Ruland disc and bellows couplings accommodate all forms of misalignment, are zero-backlash, and have a balanced design for reduced vibration at speeds up to 10,000 rpm.

 | Compact rod motors: Effective linear thrust generation
RDM-A Series rod motors from Akribis Systems are great for space-constrained applications requiring high motor forces and smooth linear motion. These compact motors feature a tubular design to distribute magnetic flux evenly along the circumference of the stator. They achieve continuous forces from 2.1 to 137.8 N and peak forces from 6.2 to 413.4 N. An air gap between the coil and magnet track enables non-contact axial linear movement and steady force production over the length of the stroke, and ironless construction ensures cog-free motion.

 | Simplify your designs with slewing ring bearings
According to Kaydon Bearings, "A slewing ring bearing has rolling elements designed to create a reactive moment within the bearing's dimensions envelope to oppose applied (overturning) moment load," so you can use one bearing instead of two, reducing the height requirements, and even improve performance. Slewing ring bearings can also simplify a drive system by utilizing gear teeth on the inner or outer race. Learn all about slewing ring bearings in this informative article.

 | Jet valve for ultra-small dispensing
DELO's DELO-DOT PN5 LV pneumatic jet valve is designed for microdispensing low-viscosity adhesives and other media in miniaturized applications. Thanks to its compact design, it also requires very little space to install in production systems. Interchangeable nozzles with different diameters and a flexible, adjustable plunger stroke ensure precise and reliable applications at different droplet sizes. Volumes of as low as 1 nl can be achieved, which corresponds to droplet diameters of 250 µm or less.
