Combined Equivalent Load

Note: Wheel bearings must handle both radial (vertical) and axial (cornering) loads. ISO 281 bearing life calculation uses combined equivalent load for L10 life estimation.
Reference
Static Radial = Corner Weight
Weight Transfer = (Axle Weight) × Lateral_G × (CG_Height / Track_Width)
Dynamic Radial = Corner Weight + Weight Transfer
Axial Load = Corner Weight × Lateral_G
Combined (ISO 281) P = 0.56×Fr + 1.2×Fa
