Cross roller ring can swing the loads Because it has orthogonally arranged cylindrical rollers, the cross roller ring from THK is a roller bearing with high rotation accuracy capable of bearing loads in every direction. Cylindrical rollers are arranged with each roller perpendicular to the adjacent roller, in a 90-deg V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions. Applications include industrial robot joints and swivel units, machining centers, precision rotary tables, and medical equipment. Rotation configurations include inner/outer ring, inner ring only, and outer ring only. Learn more about THK cross roller rings. Learn about the new Micro Cross Roller Ring RAU.

OLEDs: The future of faster long-distance wireless communications? Wi-Fi may have a real-world rival: Li-Fi. A new, record-breaking data transmission rate of 4 Gbps using organic LEDs -- the same kind found in smartphone screens and TVs -- demonstrates real potential for high-speed, long-distance visible light communications. A speed of 1 Gbps is 100 times faster than typical Wi-Fi.

Engineer's Toolbox: What they didn't teach you about fittings in engineering school Do you know why an old standard "Christmas-tree" barbed fitting may not be your best choice for your miniature fluid power application? Experts at Beswick Engineering run through the common types of fittings used in these smaller pneumatic applications, along with thread sizes and seals to help you make the correct choice. They also touch on pressure and temp ranges, chemical compatibility issues, rigid and flexible lines, and the ease of assembly and maintenance.

66 years ago: First flight of X-15 hypersonic rocket plane A joint project among NASA, the U.S. Air Force, and the U.S. Navy, the X-15 hypersonic rocket-powered aircraft greatly expanded our knowledge of flight at speeds exceeding Mach 6 and altitudes above 250,000 feet. Between 1959 and 1968, 12 pilots completed 199 missions. The results influenced the development of future programs such as the space shuttle. By John Uri, NASA Johnson Space Center
