FAGI DAC 42-80-45 Angular Contact Ball Bearing
Imagine driving on a winding mountain road. The car weighs over a ton, and with every sharp turn, centrifugal force wants to push that weight to the side. At the same time, road potholes are throwing repeated, heavy shocks at your wheels. In the middle of this silent struggle between the car’s weight, the speed, and the road, sits a small silver component: the wheel bearing.

1. The Unsung Hero: Why Your FAGI DAC 42-80-45 Matters
Imagine driving on a winding mountain road. The car weighs over a ton, and with every sharp turn, centrifugal force wants to push that weight to the side. At the same time, road potholes are throwing repeated, heavy shocks at your wheels. In the middle of this silent struggle between the car’s weight, the speed, and the road, sits a small silver component: the wheel bearing.
If this part fails, vibrates, or overheats, it can turn a pleasant drive into a nightmare—producing a howling noise, steering instability, or even wheel locking. The FAGI DAC 42-80-45 is engineered to ensure you never have to worry about those risks. It is built to keep you rolling smoothly, silently, and safely, mile after mile.
2. Decoding the DAC 42-80-45: What Do the Numbers Mean?
"DAC 42-80-45" might sound like cryptic industrial jargon, but it’s actually a simple roadmap to its dimensions and function:
🚗 DAC Prefix (Automotive Grade)
DAC signifies a double-row angular contact bearing specifically for automotive wheel hubs. Unlike standard bearings, it features two rows of steel balls side-by-side to absorb both vertical load and side-thrust during steering.
📏 Golden Dimensions (42x80x45mm)
42mm is the inner bore (where the shaft sits), 80mm is the outer diameter (pressed into the hub), and 45mm is the width. This substantial 45mm width is key to its resilience against heavy road shocks.
📐 Technical Specifications
| Parameter | Specification | Benefit |
|---|---|---|
| Inner Diameter | 42 mm | Perfect fit for wheel shafts. |
| Outer Diameter | 80 mm | Secure hub integration. |
| Width | 45 mm | Extra width for load capacity. |
| Structure | Double Row | Handles vertical & lateral loads. |
⭐ Why FAGI DAC 42-80-45 is the Right Choice
1. Silent Performance
No more high-speed humming. FAGI’s precision-ground raceways ensure quiet, smooth rotation even after thousands of kilometers.
2. Angular Contact Engineering
Designed specifically for cornering, absorbing side loads that would destroy a standard bearing.
3. Advanced Sealing
Protects your internal grease from water, road salt, brake dust, and mud.
🚘 Compatibility
This bearing is a precision match for various popular models including:
- Mazda 3 (All variants)
- Hyundai Santa Fe (Specific series)
- MVM X33 / Lifan X60 / Besturn B50
- Various Japanese & Korean sedans requiring 42BWD11/DAC428045 specifications.
🛠️ Professional Mounting Tips
- No Hammers: Always use a hydraulic press. Hammer impacts cause micro-cracks leading to early failure.
- Press Point: Apply pressure only to the outer ring when installing into the hub, and inner ring when pressing the shaft.
- Cleanliness: Ensure the housing is free of rust and debris before installation.
❓ FAQ
Do I need to add grease?
No! It comes pre-lubricated with high-temperature automotive grease. Opening the seal will damage the factory protection.
