I have a shaft that is in a vertical position. I need to support the axial (vertical) and the radial (side) force. I can understand how to support the side force with the ball bearings. I would just slip the bearings through the shaft and then create some kind of housing and bolt it to a structure close to it. But the radial force? The ball bearings I have do not have any type of set screw, so their is nothing to lock it into place.
The shaft shoud be supported both at the top and bottom by whatever it is driving and being driven by . This should be more than enff if both the drive and driven units are properlt braced
You might want to think about using a conical bearing race. It can support both rotational and thrust forces. Without knowing the specifics of the application,It's not possible to recommend a specific one. Ask again with specifics- shaft dia. rpm's- torque, etc. and I'll try to help you ! Good Luck !!
There are pressure bearings which are installed (in your case) at the bottom of a vertical rotating shaft to support the weight or downward pressure of it and reduce friction. Those bearings are usually roller or needle bearings. I have seen them also with steel balls but having an identical top and bottom plate or ring. It is unwise to use regular ball bearings with an inner and outer ring for that.
