Buy HITACHI EX120 REAR CRANKSHAFT OIL SEAL 135 X 100 X 10MM | Tonkee®

135mm: This dimension refers to the outer diameter of the oil seal. It determines the size of the seal and its fit within the engine housing.

The 135mm outer diameter is designed to precisely match the specifications of the EX120's engine, ensuring a proper seal.

100mm: This dimension represents the inner diameter of the oil seal. It corresponds to the size of the crankshaft, around which the seal fits snugly. The 100mm inner diameter ensures a tight fit on the crankshaft to prevent oil leakage.

10mm: This measurement pertains to the thickness or width of the oil seal. The 10mm thickness is crucial for providing a barrier between the engine's internal components and the outside environment. It must be thick enough to create a reliable seal, but not so thick that it causes excessive friction or interference with the crankshaft's movement.

The choice of these specific dimensions for the rear crankshaft oil seal reflects Hitachi's commitment to engineering excellence and precision.

Using an oil seal with the correct dimensions is essential to maintain the proper functioning of the engine, prevent oil leaks, and extend the overall lifespan of the machinery.

Proper installation and maintenance of the rear crankshaft oil seal are also essential for optimal performance. Regular inspections to check for wear and tear, as well as timely replacements when necessary, can prevent costly damage to the engine and ensure the excavator's reliability on the job site.
