To make sure that the Trailer Hub and Drum Assembly - 7,000-lb Axles - 12" Diameter - 8 on 6-1/2 - Pre-Greased # AKHD-865-7-2-K will work on your Rockwell axle you will need to verify which inner and outer bearing your axle uses.

The easiest way to do this is by removing one of your current hubs and looking for the bearing number stamped in the face of the bearing as shown in the included picture of the # L44649.

If your bearings are worn to the point that you cannot read the bearing number you will need to use digital calipers like the # PTW80157 to precisely measure your spindle according to the included diagram.

The # AKHD-865-7-2-K uses inner bearing # 25580 which has an I.D. of 1.75" and outer bearing # 14125A which has an I.D. of 1.25". If this matches the bearings of your current hubs this would be a great choice.

The studs of the # AKHD-865-7-2-K are 1/2" diameter.

I included a video of the # AKHD-865-7-2-K for you to take a look at.
