Power Seal Piston Rings STD 122mm 3.5x2.5x4mm

Product description

The Power Seal STD piston rings with 122 mm diameter and dimensions 3.5x2.5x4 mm are essential components in Liebherr diesel engines. They ensure combustion chamber sealing, oil control and proper heat transfer from piston to cylinder liner. Manufactured from high-strength alloys and heat treated, they provide excellent resistance to high temperatures, pressure and friction. The set is precisely matched to minimize blow-by and enhance engine efficiency even under demanding operating conditions.

Technical data

  • Nominal diameter: 122 mm
  • Ring thickness: 3.5 x 2.5 x 4 mm
  • Version: STD (standard size)
  • Material: high-strength cast iron/steel alloys
  • Temperature resistance: up to 250°C
  • Application: Liebherr diesel engines D924, D926, D934, D936 and construction machinery

Application

Power Seal piston rings are widely used in Liebherr construction machines such as crawler excavators (R902, R912, R934B), wheel excavators (A904, A914, A924), wheel loaders (LR622, LR632) and crawler dozers PR series. Installed in D924, D926, D934 and D936 engines, they provide long service life, smooth operation and reduced oil consumption. They are dedicated to heavy-duty conditions including high load, high temperature and dusty environments.

Properties

  • High wear and abrasion resistance
  • Perfect fit to cylinder surface
  • Reduced oil consumption and exhaust emissions
  • Dimensional stability at high temperatures
  • Compatibility with Liebherr repair kits

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.
