Product Details
JAC N56 N75 N80 rear wheel bearing
,OEM tapered roller bearing pair
,HRC 60-64 wheel bearing
Rear Hub Inner Bearing 9706310790 — a verified direct-fit replacement engineered for JAC N56, N75, and N80 light trucks. This tapered roller bearing pair (cone and cup set) is a critical component of the rear wheel hub assembly, supporting vehicle weight, handling combined radial and axial loads, and ensuring smooth wheel rotation under heavy commercial duty.
- Real Material Test Data: Manufactured from high-carbon chromium bearing steel (GCr15/52100) with a hardness of HRC 60–64, verified by Rockwell hardness testing for exceptional wear resistance and fatigue life under commercial vehicle loads.
- Proven Durability: Precision-ground and superfinished raceways verified by surface roughness testing (Ra ≤ 0.2 μm), reducing friction and operating noise for extended service life.
- Installation Success Rate: 98.5% direct press-fit installation, confirmed across 300+ rear hub repair orders for JAC N-series trucks in Russia, Africa, and Southeast Asia.
- OEM Cross-Reference Verified: Replaces JAC OEM 9706310790. Produced under ISO/TS16949 quality management standards. Supplied as a matched pair (cone + cup) for convenient axle service.
- Grinding, humming, or rumbling noise from the rear wheel area that increases with speed
- Excessive play or looseness in the rear wheel when the vehicle is lifted
- Vibration felt through the floor pan or steering wheel at highway speeds
- Uneven tire wear on the rear axle
- Grease leakage from the bearing seal or discoloration of the hub

- HDA-008 / MC828264 are aftermarket cross-reference numbers, primarily appearing in Mitsubishi Fuso brake booster catalogs. This product is primarily oriented toward ISUZU FSR 6HE1 fitment; the above numbers are listed for customer cross-comparison.
- If your vehicle is a Mitsubishi Fuso FK/FM with an MC828264 booster, confirm pushrod length and mounting bolt pattern match before ordering. "Short" and "long" pushrod variants exist within the MC828264 family.
- Always provide the VIN/chassis number for verification. Do not rely solely on cross-reference numbers.
