Product description

Piston Rings WBK

Description

WBK piston rings with part numbers 7380739/4980483/7380741 are high-quality components designed to provide precise sealing of the combustion chamber in internal combustion engines. Made of durable alloy steel, they ensure excellent tightness, reduce blow-by gases into the crankcase and effectively transfer heat from the piston to the cylinder liner. This guarantees stable engine operation, reduced oil consumption and long-lasting power retention.
Their design ensures even wear and optimal cooperation with the cylinder surface under high temperature and pressure conditions.

Technical Data

  • Part numbers: 7380739 / 4980483 / 7380741
  • Material: hardened alloy steel
  • Type: complete piston ring set
  • Application: combustion engines
  • Heat resistance: up to 300°C
  • Pressure resistance: above 100 bar

Application

WBK piston rings are used in diesel and gasoline engines of construction, industrial and agricultural machinery. They are a key part of the crank-piston system, responsible for maintaining engine efficiency. Ring replacement is necessary during engine overhauls, piston regeneration or when oil consumption increases and compression drops.

Properties

  • Provide high combustion chamber tightness
  • Reduce engine oil consumption
  • Transfer heat from piston to liner
  • High wear resistance
  • Extend engine service life
  • Easy installation and cylinder fit

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.
