Комплект коренных подшипников Caterpillar 390-3066

The Main Bearing Set consists of two parts, and it is separated as upper and lower which helps to maintain the precise alignment and smooth rotational motion of the crankshaft. These bearings are strategically positioned within the engine block's main bearing saddles, forming a durable interface between the stationary engine block and the rotating crankshaft.Attributes:• Withstands the demanding mechanical forces, cyclic stresses, and extreme temperatures encountered during engine operation• Provides structural integrity and the requisite degree of thermal conductivity to manage heat dissipation generated by the friction between the bearing surfaces and the crankshaft journalApplications:The Main Bearing Set is used in the assembly of the Crankshaft supporting the entire load generated by the connecting rods, pistons, and combustion forces and this load distribution minimizes stress concentration points.
