From the Aurora Bearing catalog FAQ:
"What direction is an axial load applied?
The axial load is applied through the axis of the ball bore.
What is the axial static load capacity of Aurora Bearing Company's rod ends?
For Aurora two-piece rod ends, the maximum axial static load capacity is recommended to be 15% of the ultimate radial static load capacity. For three-piece rod ends, the maximum axial static load capacity is recommended to be 10% of the ultimate radial static load capacity. However, on three-piece units, factors such as race material, body material, and dimensions may affect the axial static load capacity. For further information, consult the Aurora Bearing engineering department. "
