According to Thomson, "Precision ball splines have gained popularity as an ideal choice for applications that require low-friction linear and rotary motion. These components, which utilize a single splined shaft, enable complex movements in multiple directions." But how do you keep these ball splines performing at their peak for longer? Coatings can do the trick, and Thomson has three of them: black oxide, hard chrome plating, and nickel plating. Learn more about these coatings and which one makes the most sense for your precision ball spline solution.

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.

DELO's DELO-DOT PN5 LV pneumatic jet valve is designed for micro-dispensing 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.

NanoSteel, a leader in nanostructured steel materials, recently announced the delivery of its first advanced high-strength steel (AHSS) to General Motors for initial testing. Designed to provide automakers with a new standard in material performance, the sheet steel is poised to accelerate vehicle lightweighting initiatives focused on affordably meeting rising global fuel-economy regulations.
Production of the material, targeted to the $100 billion-plus automotive steel market, is the result of a multi-year joint development program between NanoSteel and AK Steel Corp., an industry-leading innovator in steel product development.
NanoSteel's commercially produced automotive sheet steel overcomes the historical tradeoff between strength and formability by delivering exceptional levels of both properties at the same time (approximately 1200 MPa tensile strength and 50 percent elongation). The high strength allows designers to create parts utilizing thinner-gauge material (less weight), while the high elongation allows manufacturers to produce the newly designed parts without expensive processing techniques, employee retraining, or additional capital costs. The unique combination of properties also allows engineers the design freedom to create novel part shapes, which further reduces weight.

"Many advanced materials with outstanding properties end up abandoned because they are too hard to use or too expensive to make," says NanoSteel CEO and President David Paratore. "NanoSteel's advanced high-strength steel is designed to be both easy to produce using conventional alloying elements with standard slab casting equipment and easy to use, enabling the stamping and forming of parts at room temperature without additional manufacturing infrastructure or investment, such as that required for ‘hot' stamped parts."
What sets NanoSteel apart
NanoSteel takes common raw material constituents used to make conventional steel alloys and combines them in different ratios to create proprietary alloy chemistries.
In conventional steel, the grains and matrix that comprise the structure of the steel are measured in microns. NanoSteel's alloys are nano-structured, which means grain and matrix sizes smaller than 100 nanometers. These nano-scale microstructures produce unique mechanical and physical properties resulting in capabilities outside the known performance boundaries of existing steels.
NanoSteel's technology is a "bulk materials nano-technology," which means that raw material chemistries are composed of conventional-size constituents that do not contain any nano-size particulates. Only the post-production microstructure of the thermal spray coatings, weld overlays, powder metals, and sheet steels are nano-scale in size.
NanoSteel bases the material chemistries of its patented alloys on iron, providing a competitive cost advantage given its abundance and recyclability. The company does not use any expensive, rare, or exotic constituents.
NanoSteel follows a market-driven product development model so that basic laboratory discoveries are commercialized for large-scale industrial implementation. After selecting a material chemistry that meets a desired set of properties, NanoSteel simulates actual production processes in the laboratory so that subsequent production and performance validation trials lead to a successful product launch. All NanoSteel alloys are designed for use in mainstream industries with existing manufacturing processes and widely available commercial application equipment.
