Replacement Thrust Bearing With Dimensions For A 5,000lb Bulldog Jack

Updated 05/18/2022 | Published 05/17/2022

Question:

I have a Bulldog top-wind A-frame utility trailer jack and the thrust bearing is shot. Bulldog model number unknown. I would guess it is a 5000 lb capacity. Bearing inside dia. is 1/2. Outside dia. is about 2. Thickness is unknown as it is in pieces, but could be about 5/8. Do you have one that fits this description? Your webpage on the bulldog bearings does not show dimensions.
