Speed-Pro's engineers have determined that such a layer can actually move around under high loads--sometimes with undesirable consequences. The key to reducing fatigue wear in bearings is to keep the overplating thickness to a minimum
Speed-Pro Competition Series main bearings have 3/4 oil grooves for enhanced lubrication, while maintaining a maximum bearing surface area. They also feature Speed-Pro's exclusive contoured-flange thrust bearing technology for higher thrust-loading capacity.
