Question:

current hub has outer bearing LM67048 I see you have several hub kits with outer bearing 14125A both have same inner bearing 25580. Are the two interchangeable? is the 14125a better it looks like a bigger bearing?

Expert Reply:

Although both the # LM67048 and the # 14125A bearings might have the same inner diameter of 1.25 inches, they aren't interchangeable. Both bearings are compatible with a different race or bearing cone. The races have a different outside diameter, so you wouldn't be able to simply swap out the race to change to the other bearing.

Both bearings are also rated for a different weight capacity. The # 14125A bearing is rated for a 7000 lb axle, while the # LM67048 is rated for a 5200 or 6000 lb axle.

Going with a hub that uses the higher rated # 14125A outer bearing wouldn't increase the weight bearing capacity of your trailer, as the axle and suspension ratings would still limit the capacity. Additionally, the grease seals from the higher rated hub wouldn't be compatible with your spindle.
