King Engine Bearings has developed and produced a new line of engine bearings especially designed for superior service life and performance for today¡¯s mo­­dern engines. Continuous internal combustion engine development has resulted in ever-decreasing minimum oil film thickness values, higher cylinder pressures, temperatures and loads, smaller load carrying bearing surfaces and lighter components.
In addition, start/stop technology produces more frequent mixed lubrication and metal-to-metal contact conditions. To address these challenges, King¡¯s MC line of high-strength, bimetal bearings features one of King¡¯s proprietary and in-house applied coatings. According to King, the MC bearing line offers excellent anti-friction properties, outstanding wear and seizure resistance, high load capacity and high temperature compatibility. These are the exact characteristics needed to provide superior service life and performance ¨C whether in a start/stop application or a modern small displacement/turbocharged/high output engine, the company says.
Jasper Engines and Transmissions was in on the ground floor of MC product testing and engine range coverage. King is a long-standing partner and key supplier to Jasper. Russ Hayes, product design engineering group leader at Jasper, said ¡°We put all our new engine platforms through weeks of long and severe dyno testing. For the Ford 3.5L Ecoboost, we increased our tune substantially over stock to achieve 412HP @5200 RPM and 472 ft. lbs. of torque @3400 RPM. We punished these bearings during our testing. After all we put them through, these bearings were still comparable to new ¡ the best we¡¯ve seen!¡±
King¡¯s bimetal polymer coated MC bearings are now available for Ford Ecoboost 3.5L, GM LS, Ford 5.0L/302, Subaru EJ20-EJ27, Toyota 2GR and more. All feature a 5-10 micron polymer coating layer that contains solid lubricant and ceramic additives.
