Connecting Rod Bearings

Connecting rod bearings are critical engine components located between the connecting rods and the crankshaft journals within the crankcase of passenger cars and commercial vehicles. These bearings facilitate smooth, low-friction movement as the connecting rods convert the reciprocating motion of the pistons into the rotary motion of the crankshaft. They are designed to withstand high loads and speeds, preventing metal-to-metal contact and ensuring efficient engine operation. Typically constructed from layered steel or tri-metal materials for durability and load capacity, connecting rod bearings require precise clearances for optimal oil lubrication. Examples in our assortment include MAHLE MPN 209PS20152000, 213PS19084000, and 037PS10588000. Replacing worn connecting rod bearings is essential during engine rebuilds or when addressing connecting rod knock.
