The Half Shaft / Rear Hub Oil Seal with OEM number 4204940260 is a verified direct-fit replacement for JAC N56 / N75 / N80 / N120 light truck models. It is a critical sealing component that prevents lubricating oil from leaking out of the rear hub/axle assembly and keeps dirt, water, and contaminants from entering the bearing and differential system.
How It Works: The seal is press-fitted into the rear hub or axle housing, with its lip riding against the rotating shaft. The lip maintains constant contact pressure to retain oil while excluding external contaminants. A failed seal causes oil leakage, which can lead to bearing starvation, overheating, and eventual hub/axle failure.
- Real Bench Test Data: Seal lip contact pressure [insert verified value], operating temperature range −40°C to +120°C — verified via in-house bench test against OEM specification.
- Proven Durability: Rated for [insert verified value, e.g., km/hours] under normal operation — based on [insert data source, e.g., fleet tracking].
- Installation Success Rate: [insert %, e.g., 100%] direct press-fit installation — confirmed across [insert number] repair orders for JAC N56/N75/N80.
- OEM Cross-Reference Verified: Directly replaces OEM 4204940260; cross-reference 4204930020 (alternate designation).
- Material Verification: [insert material — e.g., NBR/FKM rubber] lip with steel case — verified by [insert test method/report].
Replace the seal promptly if any of the following signs appear:
- Oil leakage visible around the rear hub or brake drum area
- Oil stains on the wheel inner surface or tire sidewall
- Differential/axle oil level dropping faster than normal
- Grinding or humming noise from the rear hub bearing (due to oil loss)
- Brake performance degradation from oil contamination on brake components
