Engine Bearings Block

Oil is distributed to the crankshaft and connecting rods through holes like these in the block's main journals. It's important for a bearing to have enough provisions for adequate oil supply but not too much so as to compromise the bearing's strength. Sizing bearings appropriately will help ensure the correct oil pressure, and thus volume, is distributed throughout.
