Distance Between Races on Dexter Trailer Idler Hub Assembly
Updated 10/31/2025 | Published 02/06/2025
Question:
Hi, What it the inside distance between the races. I want to convert a farm trailer with old mobile home axles and these have the right measurements bearing wise. I just want to make sure they are the right width as well. Thanks

Hey Mark; the inside to inside measurement between the races on the # 42660UC1 is 2-1/8". You may have a hard time finding a replacement since it uses mobile home axles even if the bearings match since they don't follow standards. Hopefully in this case it works for you. Let me know if you need anything else.
