Hi Matt!
The # LM48548 inner bearing is typically seen in the AH25555F agricultural hub, but not with an # L44649 outer bearing. This is a very odd hub/spindle you have, especially with that bolt pattern, but I am fairly sure it is a variant of Dexter's 8-147 hub. Unfortunately, this hub was discontinued quite some time ago and there is no current hub that uses this bearing combination. I did a lot of looking, but was unable to find any anywhere.
Are your hubs still in good shape? Replacing the bearings and races is perfectly fine if they are still looking good. We do not carry the L44613 race as it isn't really used anymore, but that one should still be available elsewhere.
Bearing: # LM48548
Race: # LM48510
Bearing; # L44649
Race: # L44610 (1.980" outer diameter) or L44613 (2.0467" outer diameter)
If it is looking a bit worse for wear though, the only thing we can really do is recommend replacing the axle and hubs with something that has a more common bearing combination. We would need to know the axle capacity and a few measurements if you decide to go this route (see attached picture).
Out of curiosity, how old is the trailer this hub is on? And what kind of trailer is it?

Hey Matt, Did you get a chance to check the condition of your hubs and bearings? I'm curious to know if replacing just the bearings and races worked out for you or if you decided to go with a new axle and hubs. Let me know, as it could really help others in a similar situation!
