Rear Outer Hub Bearing 9705510640 — Perfect Fit for JAC N56 / N75 / N80 / Sunray Light Truck — Verified OEM Quality with Tapered Roller Design
The Rear Outer Wheel Bearing with OEM number 9705510640 is a verified direct-fit replacement for JAC N56, N75, and N80 light trucks. This tapered roller bearing is a critical component of the rear wheel hub assembly, responsible for supporting the vehicle's weight, reducing friction between the rotating hub and the stationary axle, and ensuring smooth wheel rotation under heavy loads.
- Real Dimension Data: Precision-ground to 55.5 mm inner diameter × 97.5 mm outer diameter × 25 mm width — verified by CMM dimensional inspection against OEM specification.
- Proven Durability: Manufactured from high-carbon chromium bearing steel (GCr15) with a hardness of HRC 60–64 — verified by Rockwell hardness testing, ensuring resistance to wear and fatigue under commercial vehicle loads.
- 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 9705510640. Also cross-references to 28680/22 and 2868022. Compatible with JAC Sunray, Atlant, S35 (BJ1038), and MAZ-281/3650 applications.
Replace the bearing promptly if any of the following signs appear:
- 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 steering wheel or floor pan at highway speeds
- Uneven tire wear on the rear axle
- Grease leakage from the bearing seal or discoloration of the hub
