I just want to make sure I am understanding this right. I want to set up a round over bit in my router table so that I can completly round the edge of a 1/4 inch thick piece of stock. Would look like a half circle on the end. Am I right to use a 1/8 inch radius RO and make two passes, one on each side? First side will be done with either fence or bearing but the second will be done with fence for sure. Setting the fence even with the bearing.

yup. if you align the fence with the bearing then you don’t even need to worry about the bearing being there as you’ll be guided completely by the fence.

I do it also on portable routers using the side guide added with a straight piece of wood. Sharon is right you dont need the bearing. Sometimes I do take out the bearings. I had made a curtain rod of 1/2 inch diameter using a 1/4 R round over bit by 4 passes using the side guide. But be careful.

You’ve got it right.

An alternative to consider is a bullnose bit that will do the complete edge in a single pass. Since I own some bullnose bits, that is my preference when doing a job like this. If you were doing a high volume of rounded edges, a bullnose bit may be justified.

To add to Rich’s suggestion, using a bull nose is also a table router operation.
