Look at page #168 of the Timken roller bearing progressive size chart and find a bearing with similar inside and outside dimensions. You might need to machine the hub to fit a cone/cup part number with similar outside dimensions or cup width. There are several bearings listed there with the same 1.75" inside diameter.
