Replacement Bearing With 1.75 Inch Inner Diameter

Question:

I have an old RV type down trailer axle that I am trying to replace hub inner bearings and races. I measure the inner bearing I removed and it 1.75 ID and 2.89 OD. The spindle is tapered down from 1.75 to 1.25. I need the inner bearing, outer bearing both races and inner grease seal. I have no idea when this trailer was built as it is converted to an airboat trailer.

We do have a bearing with a 1.75 inch inner diameter, the Replacement Trailer Hub Bearing # 25580.

That said, there are numerous bearings with a 1.25 inch inner diameter, and I wouldn't be able to tell you exactly which one you need, so I've linked them below for you. Same for the grease seal I'd need the inner and outer diameters but I've also linked the selection of those for you below. You'll want to measure your spindle where the seal rides to get the inner diameter at least.
