Keeping the Wheel in Motion  Bearings, as most know, help keep wheels in motion. But what if the wheel is more than 15 stories tall, holding 40 passenger gondolas, and operating 363 days of the year? The spherical roller bearings and a portable data collector keep the Navy Pier Ferris Wheel in Chicago moving with little maintenance.

Doubling the Life of Bearings
 Hauling 80 tons of coal and dirt at a time from the earth isn't a job for wimpy machinery. When these machines break, repairs can cost $5000 an hour. In order to keep these mining electric shovels operating, a spherical roller bearing cartridge design pays off, nearly doubling the shovels' working time.

Smart Seals Go Below Grade
 As sensing materials grow smaller, they find unique mechanical components to "hide" in — such as seals designed for oil drilling equipment. These smart seals will soon report potential failure (using chemical analysis), as well as temperature, torque, and rotational speed, with embedded fiber optics and power supplies.

Springs Measured to Military Metal Standards
 The U.S. Department of Defense in the FY2007 Defense Authorization Act was granted the opportunity to create a Strategic Materials Board. In order to sell to military programs, spring wires must be sourced from the U.S. or a qualifying country. Spring manufacturers have scrambled to determine if their materials will pass military muster.

Two Dozen Chain Saws Rolling up the Highway
 Pulling the individual starting cords of 24 chain saws takes a couple minutes, but this chainsaw motorcycle can kick out 5.2 kW at 10,000 rpm. The combined power of 24 chainsaw engines is fed into a five-speed Harley-Davidson transmission by a series of twelve toothed belts. This video brings new meaning to cutting through traffic!

Assembly Tools Go Cordless
 Cordless tools have always been about power — not enough power. But these cordless impact wrenches offer a battery power supply in 7.2, 14.4, and 19.2 volt sizes. They run on nickel-cadmium or lithium-ion rechargeable batteries. Microprocessor controlled battery and charger indicate battery life and keep tools running at optimum charge.
