Im looking for an axle bearing with an ID of 1.25inch and an OD of 2. Do you have such a thing? it is for a homemade go cart. The bearing is held in place with set screws.

The very best way to find a replacement wheel bearing is to locate the part number stamped into the bearing's outer housing. Please refer to the linked photo to see the typical placement and appearance of bearing, race and seal part numbers.

When part numbers are not available it is possible to take measurements of the spindle (for the bearing's inner diameter) and the hub bore (for the bearing outer diameter).

We do have several wheel bearings with the 1.250-inch inner diameter you mentioned. These four parts are shown on the linked page and are rated for applications on axles rated for between 5000-lbs and 8000-lbs. You can refer to the two linked articles for help identifying your bearing and for guidance about the replacement process.

Please note these are all tapered roller bearings and they are not intended to be secured with a set screw.
