Can anyone tell if these bearings load ratings are for a radial load or an axial load ?
Bearing designed for an axial load is (sometimes?) called a "thrust bearing".
Based on its mounting, I guess this is a thrust bearing for an axial load.

Based on its mounting, I guess this is for a radial load.
The basic specifications are given in a table and include static and dynamic load ratings (images include a detailed mechanical drawing).
The mechanical drawing may indicate how the bearings are situated within the mounting.
For someone with more knowledge the mechanical drawing may allow you to determine if the bearing is designed for an axial or radial load.

jko answered I looked again at the mechianal drawings provided in the specifications, for illustration here is another bearing
appears to be a radial bearing meaning designed to bear a load perpendicular to the axle on which it is mounted.
As I understand it the bearing balls themselves are mounted (inside the casing, if any, of the overall bearing ) on two surfaces, those surfaces determine how the bearing is designed to carry a load, the surfaces are perpendicular to the direction of load, or one could say the load is applied to those surfaces
in my original question as i look more closesly at the mechanical drawings provided in the specs, i now see the surfaces on which the ball bearings themselves roll appear to be perpendicular to the axis on which the bearing is mounted meaning both are thrust bearings
in the link in this comment, in the mechanical drawing the surfaces on which the bearing balls roll are parallel to the axis of the bearing so that this would be a radial bearing.
This isn't an attempt to answer my question but giving my own understanding and also a comment directed towards those who may have already answered asking for clarification.
