Lithium-ion batteries will power most e-vehicles that hit the road in the next few years. But the key to efficient, perhaps even market-acceptable performance is effective battery cooling technology. With Tesla first, then Chevy's Volt, and now Ford opting for liquid instead of air cooling, the trend is cemented. An old debate was re-ignited, nudging Nissan to warrant its air-cooled system, matching Chevy's 8-year EV warranty. Ford's active thermal management system chills or heats a coolant and pumps it through the system to regulate battery temperature in a wide range of external conditions, extending both driving range and battery life.

Dodge on Demand is a shipment program that includes Dodge Ball Bearings, Roller Bearings up to a 5 in. bore size, and Tigear-2 speed reducers. Over 95% of products in these categories are included in the program and may be available for shipment within 24 hours of order entry.

DuPont™ Krytox® oils and greases help bearings run quieter and wear less, extending bearing and component life. These high-performance lubricants provide a thick lubricating film that reduces metal-to-metal contact in the bearings, resulting in superior load carrying capability. They also provide protection against corrosion and won't carbonize like conventional lubricants.

In limited rotation applications and high accuracy requirements, C-Flex bearings have no performance limitations.


• No lubrication required
• Frtiction-free
• No backlash
• Self-centering

They offer indefinite life without performance change and are tolerant of harsh environments. Standard sizes: 1/8 in.-1 in. diameter. Custom designs and special materials can be provided.

Sardello, Inc. offers cleaning, remanufacturing, and assembly services. By outsourcing your needs, you gain flexibility, productivity, and predictability within your operations. Our economies of scale enable cost-effective cleaning and remanufacturing services and our broad service capabilities, combined with a single point of contact, give you greater efficiency.

When half the Tour de France teams equip their bikes with your bearing, you know you have a winner. Racers have moved en masse to bearing cages made of PEEK. The polymer's sliding properties reduces friction while its low density contributes to quicker acceleration, making a difference at the finish line.

We expect manufacturers to conduct research to improve their products. The paybacks aren't always there. In this case, however, research on friction-causing slippage in spherical roller bearings led to a new surface treatment on the outer ring — and dramatic results: better control of rotating rollers, and doubling of the bearing life.

There are glue guns; then there are high-temp, high-tech tools that ease fastening work, even with heat sensitive materials. This microprocessor-controlled gun is designed for polyamide and polyester adhesives. It provides plenty of user help, from +/- 2F temp control in the melt tank, to fast trigger-to-discharge response, to pneumatic assistance.

For research and design, product testing or prototyping, engineers appreciate the convenience of small force sensors, designed for use with their own multimeters. This sensor, made of flexible polyester film just 0.008 in. thick, permits users to slip it into almost any tight space to measure forces of two mating surfaces, in the 0-25 lb 110N range.

Leader for over 50 years in the manufacturing of aerospace, industrial complex machine parts, and precision cams (barrel, 2d/3d cams). Core competencies include small and large turning, milling, large automated CMM, wire EDM, broaching, laser marking, engraving, cylindrical surface grinding, and much, much more.

Join WPT Power Corporation at the upcoming 2010 Permian Basin International Oil Show on October 19^th through 21^st in Odessa, TX at booth OS9 and OS10. WPT manufactures high horsepower engine-mount power take-offs for mud pumps; clutches and brakes for drawworks and water cooled tensioning brakes for mooring and positioning winches.

UK scientists have demonstrated a liquid armor that stops bullets — or at least can help Kevlar stop them. BAE developed a shear-thickening, "custard-like" liquid that reacts faster and keeps the impact shallower. It absorbed the force of a 300 mps bullet strike, quickly locking its molecules together and becoming more sticky.

Robert Gore stretched poly to create ePTFE decades ago. Yet the widely-known waterproof, breathable material continues to stretch into new uses. This clip explores some high-tension, high-stress bending applications like rope for ship anchor tow cables. The material reduces friction and wear, so provides greater longevity while also providing requisite strength.

If your project needs dependable deflection, and you can deflect up-front cost issues, machined springs are worth considering over traditional wire wound springs. Because they have no internal stresses, machined springs provide more precise, predictable deflection rates. Their perpendicularity, parallelism, axial, and torsional rates are close to a sure-thing.

Perfection isn't attainable, especially in oilfields. Drilling mud, sour gas, 22,500 psi pressure, 350 F temps all contribute to seal failure. After reviewing common seal types, this article highlights one that achieves 50% longer life. The spring-energized, graphite-reinforced PTFE ring is coupled with a thermoplastic anti-extrusion element and a metal locking ring.

WD Combined Bearings are particularly suitable for trucklift columns and all other shifting and conveying systems. WD Combined bearings that include bolt, radial part, and axial part which mounted in two directions, could save the mounting spaces and reduce the production costs.

Bearings do fail prematurely, and it's usually due to causes that might be avoided. Emerson Bearing provides 24/7 service and support to help you prevent bearing failure. Offering diverse inventory and immediate shipment of bearings and mechanical components, we can help you experience longer life for your application or need.

Where did your last fresh business idea come from? For Lucent Technologies, neither web-based suggestion boxes nor contests with incentive payments worked. Better ideas sprang from incubation boot camps, where employee groups learned to develop business plans, presented them to venture capitalists — and hoped Lucent would fund their concept.

Fifty years after developing unbreakable glass, Corning finally found a market for the material. Originally formulated to withstand pressures of 100,000 psi, glass strengthened through an ion-exchange process, is now appearing in mobile phone and laptop covers. You've probably heard of Gorilla Glass; now watch it in this tradeshow demo.
