0.50mm oversize K19 engine main bearing 205142

What is a main bearing?

In a piston engine, the main bearings are the bearings on which the crankshaft rotates, usually plain or journal bearings. The bearings hold the crankshaft in place and prevent the forces created by the
piston and transmitted to the crankshaft by the connecting rods from dislodging the crankshaft, instead forcing the crank to convert the reciprocating movement into rotation. Most modern automotive engines have one main bearing at each end of the crankshaft and another in between each adjacent pair of connecting rod journals, but not all engines conform to this generalization. Notable exceptions include the Ford flathead V-8, which often had only three main bearings, and straight-6 engine, which had in various iterations, between 3 and 7 main bearings.
