F-577986 F-577986.05 Auto Differential Bearing F-577986.05.SKL Angular Contact Ball Bearing

The F-577986.05 auto differential bearing is a high-reliability precision component engineered for vehicle differential transmission scenarios, where it must withstand complex radial-axial combined loads and frequent impact vibrations. With core dimensions of 35mm ID × 103.5mm OD × 48.15mm Width (supporting multi-dimensional installation via optional matching dimensions: 89/128mm OD, 39/51.2mm Width) , it adopts a double-row angular contact ball structure—optimized contact angles balance load distribution, while integrated raceways enhance structural rigidity for stable power transmission . Crafted from premium GCr15 chrome steel, it undergoes precision hot forging and heat treatment (58-62 HRC hardness), delivering exceptional wear resistance and fatigue strength to cope with dynamic load fluctuations during vehicle acceleration and deceleration . Equipped with low-friction rubber seals (2RS) and pre-filled lithium-based grease, it effectively isolates dust and gear oil leakage, maintaining long-term maintenance-free operation, and complies with ROHS environmental standards .

Commercial vehicle manufacturing, passenger car powertrain assembly, auto maintenance services, logistics fleet support; compatible with differential systems of:

• Mercedes-Benz commercial vehicles (matching OE specifications)
• Dongfeng Liuqi pickup trucks
• FAW Jiefang light-duty vehicles
• Passenger car models including Volkswagen Magotan and Toyota Camry

1. Q: What does the multi-dimensional size option mean for F-577986.05 bearings?

   A: The optional dimensions (89/128mm OD, 39/51.2mm Width) correspond to different differential housing structures of passenger cars and commercial vehicles, ensuring compatibility with diverse powertrain configurations .

2. Q: Can this bearing withstand only radial loads?

   A: No, its double-row angular contact structure is designed for combined radial-axial loads, which is critical for absorbing both torque transmission forces and axial thrust during cornering .

3. Q: How to ensure proper installation of F-577986.05 bearings?

   A: Use torque wrenches to control preload (recommended 15-20 N·m) and keep the installation surface clean—contaminants may cause abnormal wear under dynamic load conditions .
