011PS21045000 MAHLE Connecting Rod Bearing Set

MAHLE's Engine Bearings (MPN: 011PS21045000) are precision-engineered components designed for use in the crankcase of diesel engines. With dimensions of 81.0 x 37.0 x 60.0 mm, these bearings ensure efficient power transmission and minimize wear on critical engine parts. Originating from Slovakia, they offer a reliable solution for demanding engine applications. Dimensions are provided by the supplier and may include packaging dimensions. Connecting rod bearings are precision cylindrical components installed between the connecting rod and the crankshaft journal. They facilitate a low-friction, pivoting articulation enabling conversion of piston motion into rotational force. These bearings are typically constructed of layered steel backed with a babbit alloy or polymer coating to withstand high loads and speeds. Variations include bi-metal, tri-metal, and polymer designs, differing in material composition and load capacity. Dimensional accuracy and surface finish are critical for proper oil film maintenance and preventing crankshaft damage. Proper installation requires precise clearances verified with plastigauge or similar measuring tools.
