Picking Out Trailer Hub Bearings for 6 Lug Agricultural Hub


I have a 6 bolt hub on ag running gear used as a hay wagon. The bearings and seals have no identifying numbers on the bearings or the seal. I also do not know the make or model of the running gear. No identifying marks have been found. The bearings measure out as outside bearing 1.25 inch inside dia., outside is 2.08 inches and is .65 inch in width. I believe this is a LM67048. The inside bearing measures 1.36 inch in dia., outside is 2.27 inches and the width is .72 inches. I believe this is a LM48548. The rear seal measures as .24 inches in depth, inside diameter 1.06 and the outside dia is 2.60 inches. Can you help me identify the correct bearings and deal to repair this hub?


Helpful Expert Reply:

The bearing numbers you mentioned do check out as what you'd need with the part # LM67048 for the outer bearing and part # LM48548 for the inner.

Now the grease seal dimensions don't quite add up though. Are you sure the inner diameter of the seal or the diameter of the spindle where the seal rides is 1.06 inches in diameter? Normally the seal surface is bigger than the bearing surfaces.
