The engine bearings are the primary, central bearings in an engine. They perform a crucial function; to hold the crankshaft to the engine block and allow it to spin. The thrust bearing, in turn, controls the forward-backward movement of the crankshaft.

AEC bearings are manufactured with tight tolerances ensuring consistency of bearing to journal clearances.

High melting point of AEC bearings ensures added protection against localised overheating caused by overloading, denotation, misalignment and lack of coolant.
