It sounds like you're trying to replace hubs on a mobile home axle. Mobile home axles are designed for one time use, to transport the mobile home from point A to point B and then intended to be discarded after that. Because of this, replacement parts are rarely available for most mobile home axles and although we don't have a hub that matches the bearing sizes you mentioned, we have replacement bearings that may work to service your existing hub.

For a bearing with a 1.375 inch inner diameter, we have # LM48548, which uses race # LM48510 with a 2.563 inch outer diameter and is sold separately.

We have four bearing options that have a 1.25 inch inner diameter. I'll list them below along with their matching races available separately.

# 02475 which uses race # 02420 (2.688 OD)
# 14125A which uses race # 14276 (2.717 OD)
# 15123 which uses race # 15245 (2.441 OD)
# LM67048 which uses race # LM67010 (2.328 OD)

The closest grease seals we have are part # BB60002, with a 2.562 inch OD and 1.875 inch ID. The 0.025 inch discrepancy should not make much of a difference but this will depend on how accurately you measured the portion of the spindle on which the seal rides. I recommend using a digital caliper like # PTW80157 to confirm the accuracy of all your measurements.
