The magnet used in trailer brake assemblies # AKEBRK-7-SA is magnet # AKBRKR-M12 which you will see they have rated the same as the brake assemblies themselves. So since they are compatible with up to 7K axles you can say they are rated for 7,000 pound axles maximum.

We have tow hub and drum assembly kits for 7K oil bath axles. First is # 8-219-9UC3-A and it comes with a 2-1/4 inch diameter seal. The other is # 8-219-9UC3 and it comes with a 2-1/8 inch diameter seal. The oil cap included with both is # RG04-230 which has a threaded diameter of 2-7/8 inches which is 1/8 inch larger than 2-3/4 inches so if you were using a ruler or tape measurer to measure the diameter that could account for the slight difference.

Both assemblies use Inner bearing 25580 and Outer bearing 14125A so the only difference is the seal diameter.
