Replacement Trailer Hub that Uses Bearings with Inner Diameters of 1.25 and 0.75 Inches

Question:

I have a small trailer that needs both hubs. The original hubs were lost during a house fire. The spindle outer bearing surface is .75, the inner bearing surface is 1.25, the seal surface is 1.625. Are these measurements enough to determine what hub will fit?

Based on the measurements you have provided hub # AH15450ECOMP is a close match. The bearings that it uses fit on spindles with the measurements you have provided. But the seal has an inner diameter of 1-1/2 inches. It is not uncommon for the seal inner diameter to be smaller to provide a tight fit.

This is an agricultural hub so it isn't very common and being an aggie hub means it is limited to 20 miles per hour.

It might be more beneficial to replace the axle on the trailer to get more common hubs that will have readily available replacement parts. We have some axles, see link, but if not match what you need then you could order one from a local trailer supply store.
