 | Noisy Bearing??
Smalley wave springs are ideal for bearing preload. The wave spring preloads the bearing through its outer race, taking up play in the bearing. Preloading will reduce bearing damage, wear, noise and vibration. The wave spring prevents sliding between the rolling elements. Bearing springs come in metric sizes to match popular bearing sizes. Smalley has over 150 standard springs available, from .157 to 120". Customs are available for unique bearing sizes with No-Tooling-Charges™.

 | New 22mm Brushless Servo Motor Packs a Punch
Introducing the new FAULHABER 2264 BP4 series brushless dc servo motor. At 22 mm in diameter and 64 mm in length, the 2264 BP4 series delivers 59 mNm of continuous torque and reaches speeds up to 34,500 revolutions per minute. These impressive power and performance capabilities are possible due to a new segmented winding of the coil, which also improves overall efficiency of the motor.

 | NASA green-lights commercial space station module
"The human dream of universal access to living and working in space has drawn one step closer." At least that's what Axiom Space says, now that the Houston, Texas-based company? has been selected by NASA to provide at least one habitable commercial module to be attached to the International Space Station. The project could ultimately serve as the replacement for the ISS.

 | Large and in charge: 2021 GMC Yukon and Yukon XL
If a big and tall shop existed for SUVs, you'd find the 2021 Yukon and Yukon XL models front and center. You couldn't miss them, though, even if they ended up in the back. GMC's next-gen flagship large SUV line is headlined by an all-new and more upscale Denali and the first-ever, ride-higher Yukon AT4 targeted for off-roading.

 | The battle of stainless: 303 vs. 304 vs. 316
Choosing the correct stainless steel material is critical to any application -- especially those designed for wash-down, corrosion resistance, heat resistance, or strength. There are a variety of materials to choose from, with many different specifications tied to them. But do you know the differences between the most widely used grades? Carlicia Layosa from MISUMI gives the rundown.

 | How to avoid premature linear screw actuator failure
At their core, electric linear screw actuators deploy mechanical technology such as ball bearings, ball screws, and roller screws that have a finite life. These components do not last forever -- even though that is the expectation of some customers. But how long will an actuator really last? Tolomatic engineers provide a way to calculate, estimate, and size the electric linear screw actuator to achieve the desired life for your applications.

 | SmartMotor with IP65 protection
Moog Animatics has just released their fully featured and integrated Class 5 S-Style SmartMotor with IP65 protection in the frame sizes NEMA 23 and 34. These SmartMotor products come equipped with industry-standard M connectors, as well as an optional brake. The S-Style SmartMotor servos share many of the same components as the Class 5 D-style motors, which don't have IP protection. This significantly reduces production costs and sales prices, resulting in an excellent price-performance ratio.

 | Benefits of hybrid bearings
Hybrid bearings have shown good performance in poor lubrication and contaminated conditions, but the understanding of the contributing mechanisms and their effect on performance is still lacking. SKF has developed more insight into the tribology of hybrid bearings through both dedicated experiments and modeling.

 | Spinning flare nuts eliminate loose fasteners in thin metal sheet applications
PEM SFN spinning flare nuts from PennEngineering become permanently captivated upon installation in thin metal sheets and, when paired with a self-clinching stud or other fixed externally threaded hardware, can eliminate all loose fasteners (including flange nuts) in attachment applications. These one-piece, flanged hex nuts additionally will spin freely in a sheet, enabling quick attachment to mating hardware. Their use ultimately promotes savings in assembly time and costs.

 | igus unveils first plastic-steel hybrid energy chain
igus has developed the first plastic-steel hybrid energy chains for safe and compact vertical guidance of cables and hoses. The new energy supply system, called the YE.42, is 50 percent lighter than conventional steel chains due to the high-performance polymers manufactured by igus. The hybrid chains also provide 50 percent more unsupported length than plastic energy chains and have higher rigidity. The chains are easy to assemble and maintain due to their modular design, and operators can rely on work platforms or vertical lifts for a safe, lightweight, cost-effective, and quickly replaceable system.

 | Update: New vertical lift capabilities take flight during Army demo
Army officials joined industry leaders earlier this month to get a closer look at cutting-edge capabilities for future vertical lift to replace the UH-60 Black Hawk. Developers from Bell Textron demoed their part-aircraft, part-helicopter Bell V-280 Valor. Another helo mock-up, the Sikorsky-Boeing SB-1 Defiant, is expected to flex its muscles and show further airlift capabilities next month at Sikorsky's facility in West Palm Beach, FL.

See paper 'explode' in 144-ton hydraulic press
Annihilated any good books lately? The affable experimenters over at the Hydraulic Press Channel are at it again, this time using their hydraulic press to crush a stack of printer paper, paperback books, pure paper pulp, playing cards, and more. The results are surprisingly energetic, and the big-bang payoff is greater than many other things they've crushed in a while.
