Axle end bearing transfers the wheels rotation into the vehicle’s horizontal movement, and undertakes the radial load and axial load. So railway vehicles have high demand for the axle end bearing’s reliability.
The models of axle end bearings:
| Model | Dimension | Standard | Application | Net Weight(kg) |
| AAR C | 5〞×9〞 | AAR M-934 | Axle load ≤16t | 24.8 |
| AAR D | 5-1/2〞×10〞 | AAR M-934 | Axle load≤21t | 26.3 |
| AAR E | 6〞×11〞 | AAR M-934 | Axle load≤25t | 33.5 |
| AAR F | 6-1/2〞×12〞 | AAR M-934 | Axle load≤30t | 48 |
| AAR K | 6-1/2〞×9〞 | AAR M-934 | Axle load≤30t | 46 |
| AAR G | - | AAR M-934 | Axle load≤35.7t | 59 |
