| You need an engineering bearing application book that shows rated load for each bearing and then a vendor of bearings with a wide variety like Baum Hydraulics. Tapered roller bearings come in a wide variety of diameters and widths. You get more load handling capability including thrust by going larger in diameter for the same shaft size and going wider. Most contemporary disk bearings are ball bearings, and even if you look at Shoup you will find them in a wide variety, bigger should take more load. But if you want tapered roller, go look up a JD BW or BWA disk, it used a double tapered roller bearing assembly that is still available from Shoup but costs three or four times the modern single row ball bearing. A severe limitation on bearing selection for disks comes from using square shafts, those are unique to disks.
