Connecting Rod Bearing Set 4-3910RA50MM is a premium A-series bi-metal aluminum alloy A-Series (RA A) Sealed Power A-Series bearings are the latest in a long line of exclusive Federal-Mogul innovations. These ultra-modern bi-metal aluminum alloy bearings feature a high-strength steel backing and a patented lining material consisting of aluminum, tin and a small percentage of silicon. The use of silicon significantly increases the bearings wear resistance, even in cases when the crankshaft finish is not optimized. (Infact, A-Series bearings will actually help polish the crank in these applications)These bi-metal aluminum alloy engine bearings are the product of choice for most vehicle manufacturers. The to A-Series bearings by production engine builders is due to the benefits of this new technology.Lets Talk about the features and design character Sealed Power's Speed-Pro DUROSHIELD Competition Series Coated Bearings ~Crush Crush refers to the press fit that results from having a small section of the bearing extended above the housing bore when the bearing half is in set in place. Federal-Mogul's performance bearings have additional crush built into the design. This extra material helps to force the outside diameter of the beating against the rod or main bore when the assembly is torqued to specification. By increasing the surface contact between the bearing and it's bore, crush helps to compensate for bore distortion and aids in heat transfer. This is critical because the lubricating oil will break down and cause bearing failure if the area gets too hot.~Chamfer Performance engines often require added crankshaft strength, which mandates special bearings. Racing crankshafts employ a larger diameter fillet radius in the area where the rod journal meets the couterweight. This rounded inside corner increases crankshaft strength, but can interfere with the rod bearing. Many of their performance rod be
