Looking For Replacement Bearing For Square Tube Top Wind Trailer Jack

Updated 05/05/2026 | Published 05/02/2026

Question:

I have a square tube top wind trailer jack. I don’t see a manufacturer name on it. It disassembled like your tdJ-7000. By bearing is shattered into pieces. I am trying to find a bearing. My shaft measures 5/8” which is smaller than yours.

Hey Walker, thanks for reaching out, and thanks for the pictures. We do have a bearing for the TJD-7000 jack part # TJD-7000-BR but its a 0.75" ID/ 1.519" OD so it sounds like this won't match up with your jack. Without knowing the brand its hard to say exactly which bearing to use, so at this point I'd have to recommend replacing the entire jack with a new one like the TJD-7000.

What kind of trailer is this on?
