Government mandates have put automotive brands under pressure to meet stringent CO2 emission targets. To reduce fuel consumption, OEMs are developing timing drive systems that improve the efficiency of internal combustion engines (ICE) in conventional and hybrid drivetrains.

Key timing drive system components need to be made from materials offering excellent wear and friction behavior. Timing chain guides require low friction to optimize fuel economy, and excellent resistance to abrasive and pitting wear that can cause premature part failure. Support arms must offer high stiffness and fatigue resistance to keep chains in place, even at high speeds.
