Main Bearings 0.25 Kolbenschmidt 77914610

Product Description

The Kolbenschmidt 0.25 main bearings with catalog number 77914610 are high-quality crankshaft components designed for Cummins and Iveco engines. They ensure maximum durability, precise crankshaft operation, and reduced friction losses. With an oversize of +0.25 mm, they allow crankshaft regrinding and restoration of the engine’s original performance. Kolbenschmidt bearings are known for their resistance to dynamic loads, high temperatures, and wear, making them a trusted choice for construction machinery, trucks, and buses.

Technical Data

  • Catalog number: 77914610
  • Oversize: +0.25 mm
  • Material: steel with anti-friction coating
  • Mounting diameter: OEM Cummins/Iveco standard
  • Compatibility: Cummins 4BT 3.9, 6BT 5.9, ISB 3.9, ISB 5.9 engines and selected Iveco units
  • Working temperature: up to 250°C
  • Oil pressure resistance: above 10 MPa

Application

Main bearings are used in combustion engines as crankshaft bearing elements. Replacement is required during major engine overhauls, when bearing surfaces are worn or after crankshaft regrinding. Kolbenschmidt 0.25 main bearings are dedicated to Cummins B series engines (3.9 and 5.9) used in construction machinery, trucks, buses, and power generators. They also fit certain Iveco engines and Komatsu applications.

Properties

  • Precision engineering – ensures stable crankshaft mounting and quiet engine operation.
  • High durability – manufactured from alloys resistant to wear and high temperatures.
  • Repair oversize – +0.25 mm size enables crankshaft regeneration.

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.
