They may be originals or replacements.
Both Dexter and Alko axles use non USA made bearings a lot for brand new axles. Most now say made in China. However other countries show up too. They can be mixed across the TT as a set. However I would not recommend using each Ĺ of one from a different vendor. Meaning the bearing cone from one brand and the race cup from another.
And unless you specify at the parts store you will be hard pressed to find USA made trailer bearings in those sizes. If you want the high end quality and it is still available, search for Timken. Properly greased they will out live the TT. The price however is also about 4 to 6 times more.
Trailer wheel bearings and grease seals have gone the way with ST trailer tires. You have to work at it to find a made in USA stamped one.
