Why hybrid bearings are becoming the new industry standard

A combination of steel outer and inner rings with ceramic balls or rollers is giving hybrid bearings unique properties, making them suitable for use in a wide range of modern applications. SKF hybrid bearings make use of silicon nitride (twice as hard as bearing steel) rolling elements and are available as ball bearings, cylindrical roller bearings, and in custom designs. From electric erosion prevention to friction reduction and extended maintenance intervals, learn all about next-gen hybrid bearings.

What are carbon composite bellows springs?

The Carbon Composite Bellows Spring (CCBS) from MW Components is a system of carbon fiber elements that combine to work as a high-performance, lightweight, and design-flexible compression spring meant to replace coil springs or metallic Belleville disc springs. A functional spring is made from several individual elements paired and joined to make a stack. The stack spring rate is determined by the number of elements, the base rate of each element, and their series or parallel orientation in the stack. Applications include motorsports, aerospace, and high-performance activities.

General Motors sued by consumers for allegedly installing multiple emissions-cheating defeat devices in over 705,000 Duramax diesel trucks

Consumers are suing General Motors for allegedly rigging the emissions controls in Duramax diesel trucks in order to pass emissions tests, while in real-world conditions the trucks emit two to five times the legal limits of NOx pollutants, according to auto-defect consumer-rights law firm Hagens Berman.

The lawsuit states that GM did so allegedly to increase the vehicles' power and efficiency, and thus the appeal of its best-selling pick-up trucks. The complaint identifies and describes three distinct "defeat devices" that turn down or "de-rate" the emissions controls in place compared to when the vehicles are in a testing environment.

Vehicle owners are represented by Hagens Berman, which has been involved in many of the largest automotive settlements in U.S. history, including the $10 billion Volkswagen diesel emissions settlement, the $1.3 billion Volkswagen dealer settlement, and the $1.6 billion consumer settlement against Toyota. Based on its testing of emissions control systems, the firm is also leading litigation against Chevrolet, Fiat-Chrysler, and Mercedes for illegal use of emissions-cheating software.

The complaint, filed on May 25, 2017, in the U.S. District Court for the Eastern District of Michigan (Detroit), states that roughly 705,000 Silverado and Sierra diesels are on the road. It alleges: "By reversing the traditional order of the exhaust treatment components and putting the Selective Catalytic Reduction ("SCR") in front of the Diesel Particulate Filter ("DPF"), GM could obtain and market higher power and efficiency from its engines while still passing the cold-start emissions certification tests. This made GM's trucks more appealing and competitive in the marketplace, driving up sales and profits."

The alleged defeat devices combine to de-rate and degrade emissions controls: (1) above 86 degrees Fahrenheit -- the upper limit for emissions certification testing; (2) below 68 degrees Fahrenheit -- the lower limit for emissions certification testing; and (3) after 200 to 500 seconds of steady driving -- a scenario that never happens during certification emissions tests. When this third defeat device is active, emissions increase on average by a factor of 4.5. As a result, the trucks appear to comply with emissions regulations when they are being tested, but otherwise gain power and efficiency by dumping vast quantities of NOx into the air.

The suit also names Bosch as a defendant. Bosch developed, manufactured, and tested the Electronic Diesel Control unit that allowed GM to implement the defeat devices, according to the suit. And Bosch control units are found in almost all of the vehicles found or alleged to have been manipulating emissions, including Mercedes, Fiat Chrysler, and Chevrolet.

"These claims are baseless and we will vigorously defend ourselves," said Pat Morrissey, GM Corporate Communications, in a May 25, 2017, company statement. "The Duramax Diesel Chevrolet Silverado and GMC Sierra comply with all U.S. EPA and CARB emissions regulations."
