Product description

Main Bearings Cummins QSC / QSL

Description

Main bearings for Cummins QSC / QSL engines (part numbers: 3945918, 3802211, 3802141) are essential components ensuring proper operation of the crankshaft. They reduce friction between the crankshaft and the engine block while maintaining rotational stability. Thanks to precision manufacturing and durable materials, they provide long service life even under intensive use.
The bearings are highly wear-resistant and ensure proper lubrication of the friction surfaces. Their replacement is mandatory during engine overhauls, as worn or damaged bearings may lead to severe failures such as crankshaft seizure.

Technical Data

  • Part numbers: 3945918, 3802211, 3802141
  • Inner diameter: matched to Cummins QSC / QSL crankshaft
  • Material: high-temperature and wear-resistant alloy
  • Design: two-piece semi-circular bearings
  • Application: crankshaft of Cummins QSC / QSL engines

Application

Main bearings are used in Cummins QSC and QSL engines applied in construction machinery, power generators, marine units, and special vehicles. Their proper function is crucial for smooth and safe operation of the entire engine. Replacement is required during general overhauls or when symptoms of wear appear, such as knocking or low oil pressure.

Properties

  • High resistance to wear and pressure
  • Stable oil film retention
  • Reduced friction and energy loss
  • OEM quality compliance
  • Easy installation and perfect fit to crankshaft

Opinion 5/5

Zakupiony komplet siłowników do Liebherr 564 był w doskonałym stanie, zgodnie z opisem i przesłanymi zdjęciami. Obsługa na wysokim poziomie, bardzo profesjonalna i pomocna – rewelacja. Co więcej, w kontakcie z firmą otrzymałem osobistego opiekuna, który zajmował się sprawą od początku do końca, mogłem również liczyć na bezpłatne doradztwo przy montażu. Szkoda, że w obecnych czasach nie spotyka się zbyt wielu firm z tak profesjonalnym podejściem do klienta. Gorąco polecam.
