Product description

Piston rings – reliable part of the piston-crank system

Piston rings are crucial components for the proper operation of an internal combustion engine. They provide sealing between the piston and the cylinder wall, regulate oil flow, and maintain optimal compression. Their correct operation translates into engine performance, component durability, and reduced fuel and oil consumption.

Product description

The presented piston rings are high-quality replacements, intended for various types of engines used in construction machinery, agricultural vehicles, and heavy-duty trucks. Manufactured with precision processes and alloyed steels, they ensure high resistance to wear, temperature, and working pressure. These rings meet the requirements of users expecting reliability and long service life.

Technical data

  • Material: hardened alloy steel
  • Temperature resistance: up to 250°C
  • Nominal diameter range: according to engine specification
  • Application: diesel and petrol engines
  • Ring types: sealing, oil scraper
  • Durability: extended service life due to wear resistance

Application

Piston rings are used in internal combustion engines of:
  • construction machinery (excavators, loaders, bulldozers)
  • agricultural tractors
  • power generators
  • trucks and vans
  • industrial machines and stationary engines
They are essential for engine overhauls or replacing worn parts to restore efficiency and factory performance.

Properties

  • High sealing – minimizes blow-by gases into the crankcase
  • Wear resistance – longer lifespan even under harsh conditions
  • Stable engine operation – ensures proper compression and reduced oil consumption
  • Versatility – compatible with many engine models
  • Cost-effectiveness – reduces repair costs while maintaining high quality

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.
