What Is the Difference Between a BTR and BT8 Spindle
Question:
Hi. Im wanting to buy new wheel hubs for my utility trailer. Seems I will need a BTR or a BT16 wheel hub but I dont understand the difference in these two hubs. Can you please explain?

Expert Reply:
The BTR and BT8 denotations refer to the spindle, not the trailer hub. The difference between a BTR and BT8 spindle is that the BTR spindle uses a 1.063" diameter L44649 bearing and the BT8 spindle uses a 0.99" diameter L44643 bearing. In order to find out which you have you will need to pull the hub and either measure the spindle or look for the bearing numbers on the bearing.
If you have BTR spindles then you can use part # AKIHUB-440-2-2K.
