NVD48A-2U Main bearing：
Size : standard, 1pp 2pp, 3pp.
Made of a highly wear-resistant alloy (such as a copper-lead alloy or a steel-backed composite), the surface may be treated with special treatments (such as tin or silver plating) to enhance pressure resistance.
NVD48A-2U Connecting rod bearing
Size : standard, 1pp 2pp, 3pp.
Skoda 275 PN Main Bearing introduction：
1) A split structure is used, bolted to the connecting rod big-end bearing cap to ensure precise fit with the crankpin.
2) The bearing surface typically has a copper alloy lubricating layer and is equipped with oil grooves to optimize lubrication distribution and reduce high-speed friction and wear.

G60 Connecting rod bearing
Connecting rod bearings are usually made of alloy steel, with a circular or I-shaped main body and bronze bushings or needle bearings at both ends, and are articulated by a shaft pin.
1.The connecting rod big-end bearing must withstand cyclical impact loads and frictional wear, requiring high fatigue strength and wear resistance.
2.The bearing's inner diameter mates with the crankshaft journal, while its outer diameter connects to the connecting rod small end, achieving axial positioning via a bushing.
For 4-Stroke engines, we can also supply intake valve, exhaust valve, pistons, main bearing, conrod bearing, piston rings, plunger pair, nozzle, injector , bushing etc.
