Piston Rings STD WBK

Description

STD piston rings by WBK are high-quality components designed for combustion engines used in construction and industrial machinery. Their main purpose is to seal the combustion chamber, regulate oil consumption, and improve engine efficiency. Precisely manufactured rings minimize energy losses, ensure proper lubrication, and reduce emissions. Made from durable alloy steel, they withstand high temperatures and pressures, guaranteeing long-lasting and reliable performance.

Technical Data

  • Nominal diameter: STD
  • Material: hardened alloy steel
  • Thermal resistance: up to 250°C
  • Pressure resistance: up to 200 bar
  • Part numbers: 7382128 / 7381247 / 7381248

Application

Piston rings are used in diesel engines installed in construction, road, agricultural, and industrial machines. They are suitable for excavators, wheel loaders, bulldozers, and power generators. They are also essential in major engine overhauls where restoring full compression and performance is required.

Properties

  • Precise fit to the cylinder surface
  • High resistance to mechanical wear
  • Stable operation at high temperatures
  • Effective sealing of the combustion chamber

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.
