High-Strength Bearing Steel Differential Bearing with Improved Seals and

Precision-engineered differential bearing supports the differential assembly, ensuring smooth power distribution, reduced friction, and reliable drivetrain performance in JAC N80 and N75 trucks.

• OE Quality: Manufactured to strict dimensional and material specifiions for perfect fit and function
• Premium Material: High-quality GCR15 bearing steel provides exceptional strength and wear resistance
• Advanced Heat Treatment: Enhances toughness, durability, and load-carrying capacity
• Precision Polished Surface: High-level polishing technology ensures smooth operation and reduced friction
• Improved Sealing: Enhanced seals reduce friction and protect against contamination
• Synthetic Lubricant: High-quality lubricant inhibits rust and prevents corrosion indentation
• Long Service Life: Engineered to withstand the rigors of heavy-duty commercial operation

This differential bearing is specifically designed for JAC medium-duty trucks:

• JAC N80 – Medium-Duty Trucks
• JAC N75 – Medium-Duty Trucks
• JAC N90 (select models with compatible differential configurations)
• JAC N56 (select models with compatible differential configurations)
• JAC Light Truck Series – Various compatible models with matching differential specifiions

Differential Appliion: Rear axle differential assembly (side bearing position) - Supports differential case and gears within the carrier

Professional installation required. Proper differential service is critical for drivetrain reliability:

1. Raise and secure the vehicle – Safely lift the rear axle and support on jack stands
2. Drain differential oil – Drain the lubricant from the rear axle differential
3. Remove the differential carrier – Remove the drive shaft, axle shafts, and differential carrier assembly
4. Remove the old bearing – Carefully remove the old differential bearing using a bearing puller
5. Clean the differential housing – Thoroughly clean the housing, removing all old lubricant and debris
6. Inspect the differential components – Check the ring gear, pinion gear, and other bearings for wear
7. Prepare the new bearing – Apply a thin coat of high-quality differential gear oil to the bearing
8. Install the new bearing – Press the new bearing into the differential housing using proper tools
9. Reinstall the differential carrier – Position the differential carrier and install bearing caps
10. Adjust bearing preload – Set bearing preload per manufacturer specifiions
11. Check gear backlash – Verify ring and pinion gear backlash is within specifiion
12. Install axle shafts and drive shaft – Reinstall axle shafts and the drive shaft
13. Refill with lubricant – Fill the differential with correct grade and amount of gear oil
14. Test operation – Test drive the vehicle and check for smooth operation
15. Check for leaks – Inspect the differential housing for any lubricant leakage
