Consistent demand for engine downsizing and CO2 reduction is driving suppliers to ever-greater efforts in providing appropriate components.

Speaking at Federal-Mogul's Technology Day in its German plant of Burscheid near Cologne last week, the supplier outlined the impact market pressure is having on component producers.

"The market is clear," said Federal-Mogul director, application engineering, bearings, Gerhard Arnold. "Downsizing [and] emissions reduction are what drives our customers and we have some challenges - this is the challenge we have to face from the market.

"Even though our parts are not directly linked to the fuel, we have some effect on the bearings. Engine bearings should typically last for the life of the engine."

Increasing use of fuel-efficient technology such as stop-start in hybrid applications can see engines turned on and off 400,000 times, while for city buses for example, that number could soar to millions, requiring advanced supplier input.

"For all these concepts, we have really a wide range of bearing models and all of these models are lead-free," said Arnold.

To meet some of those stop-start needs, Federal-Mogul has developed its IROX polymer-coated engine bearings that are now with four of the largest OEMs.

The supplier says its IROX bearings enable reduced fuel consumption and CO2 emissions, while withstanding heavy mechanical loads in boosted engines, while also addressing lubrication challenges associated with frequent stop-start.

Federal-Mogul says it expects to produce more than 70m IROX bearings per year from 2016, with 30% of engines in North America featuring the application for light and heavy-duty vehicles.

Additional capacity will be provided in North America, Europe and Asia to meet the demand.

Engineering for IROX is undertaken at Federal-Mogul's technical facilities in Wiesbaden, Germany and Plymouth, Michigan and manufactured at several global locations.
