What is the Difference Between Trailer Hubs # AKIHUB-440-2-G-1K and # AKIHUB-440-2-G-2K

Question:

I need to order a trailer hub assembly but am confused... What is difference between AKIHUB-440-2-G-1K and AKIHUB-440-2-G-2K? Also, it says for BT8 spindles. I have a straight 1inch spindle but do not know what a BK8 spindle is. Waiting for your response to order... Thanks

The two hubs you mentioned, # AKIHUB-440-2-G-1K and # AKIHUB-440-2-G-2K fit different spindles. More specifically they use different bearings and seals.

First, hub # AKIHUB-440-2-G-1K uses L44643, with a 1 inch inner diameter, as the inner and outer bearing, and the seal is a 34823, which has an inner diameter of 1.249 inches and outer diameter of 1.983 inches. Based on your information this sounds like the correct replacement. Check your old bearing numbers or you can take measurements (see picture) with calipers such as # PTW80157 to measure the spindle.

Hub # AKIHUB-440-2-G-2K uses L44649 bearings with a 1.063 inner diameter and seal 10-9 with inner diameter of 1.5 inches and outer diameter of 1.987 inches.
