How To Determine What Hub Assembly is Needed With a Bearing Inner Diameter of 3/4 Inch

Question:

I need a new 4 on 4 hub and not sure if I need the 1 or 1 1/16 size. I took the bearing out and its 3/4 Inside diameter. Does that tell you enough?

The Dexter Trailer Hub Assembly - 4 on 4, part # 34822BX, uses the # L44643 bearing as the inner and outer bearings. The inner diameter of the bearing on this hub will be 1 inch.

The Dexter Trailer Hub Assembly - 4 on 4, part # 8-91-05UC1, uses the # L44649 bearing as the inner and outer bearings. The inner diameter of the bearing is 1.063 inches (1-1/16).

The only bearing I have that has a 3/4 inch inner diameter is the Redline Bearing, part # LM11949, which is used as an outer bearing on the Agricultural Hub Assembly - 4 on 5, part # AH15450ECOMP. This is a hub that has a 4 on 5 inch bolt pattern and is used for low speed (less than 20 mph) agricultural applications.

The best way to verify what hub you might have is to get the part numbers off of the bearings and seal, so I can match them up to the correct hub assembly. If the part numbers are not available you will need to measure with a precise instrument, like a digital caliper, the inner diameters of both inner and outer bearings.

I am including a link to a page that will list the dimensions on all of the bearings we carry.
