MAIN BEARING SET, Premium, 200, .020 inch oversize, full groove, 7 journal set, Bearing shells produced in steel and lined with aluminum/tin or aluminum/tin/silicon have extremely effective anti-friction properties combined with high wear strength and exceptional resistance to corrosion, The fairly soft tin provides good conformability of the bearing to the crankshaft and is an excellent surface for embedment of dirt particles occurring as wear debris and primary dirt in the engine oil, Silicon, as an alloying element in aluminum bearings, is necessary when using cast iron crankshafts, especially “soft” shafts, The silicon smoothes the crankshaft surface to overcome any folded and smeared metal that might be covering up carbon inclusions, Besides being a standard material for main bearings, steel/aluminum is also used for connecting rod bearings, Its use is restricted by the limited specific load-carrying capacity of this group of materials, but new advancements in bearing alloys provide remarkable fatigue strength allowing the use of Al/Sn/Si alloys in nearly all gasoline-engine applications,
