 | Engineer's Toolbox: 9 considerations for specifying a slewing ring bearing
In applications that require a bearing to support a structure while it rotates (e.g., cranes, radar, tank turrets), premature bearing failure can put people and equipment at risk. While slewing ring bearings have proven themselves countless times in such applications, designers must consider many factors when specifying them. The bearing's support structure, mounting (including bolt strength, tensioning, and hole patterns), installation, and even storage are all factors in a bearing's success or failure.

 | When metals can't take the heat: Silicon Carbide is a top choice for high-temperature wear
Silicon Carbide is among the hardest of ceramics. It retains this hardness and strength at elevated temperatures, which translates into incredible wear resistance. Several grades of Silicon Carbide optimize wear performance for bearings and other parts requiring extreme precision in high-acceleration or aerospace applications. Insaco is the expert in precision machining SiC in applications where thermal conductivity or strength at high temperatures and low density are key.

 | Comprehensive guide to laser cutting parameters
Certain properties, or laser parameters, such as power, wavelength, and polarization, characterize the behavior of the laser. You won't achieve the highest-quality cutting results unless you first understand the parameters and the ways they impact the final product. This article from Xometry discusses the ideal laser parameters, their definitions, and their benefits.

 | New ultrasonic metal welder for bonding larger pieces
Emerson's new Branson GMX-HP ultrasonic metal welder combines greater power and downforce, essential for larger welds required by electric vehicles, batteries, and energy storage systems. It boasts a modular equipment design and features that simplify installation and automation for machine builders and manufacturers. It provides increased weld power, furnished by a high-capacity 8-kW, 20-kHz power supply. Welding power is transmitted through a direct-press actuator, equipped with dual linear bearing guides, precision distance sensors, and a dynamic pressure trigger. Applications include high-energy batteries, large cross-section wire terminations, and busbars.
