Question:

Looking for new hubs for some trailers, seems I can not search by spindle size. I have a 0.75 dia and 1.25 dia spindle on my trailers. Need complete idler hub to match, prefer pre press, with seals. Need to make sure the pilot dia on the hub for wheel mount is NOT the 3.19, but the smaller size under 3, as it seems no one can find 8 and 10 in wheels with 3.19 pilot holes. Lot of people looking online, guess not in production anymore.

The only hub we carry that will fit your spindle size is the Agricultural Hub # AH15450ECOMP, as most have changed over to the more common BT8 # TRU59FR and BTR # TRU44FR. The agricultural hub is only rated for speeds up to 20mph and uses a 4 on 5" bolt pattern.

You can have your spindles replaced to one of the more common sizes but this is best done at a trailer manufacturer so they can true up the ends of the spindle to ensure it is welded on straight. Otherwise if you can give me dimesnions on your axle(hub face to hub face and spring center to spring center) I can help you look at replacement axle options you will be able to bolt on.
