Yup a lesson I learn in regards to purchasing cheap bearings on line last year as well .... after only about 500 miles of use I had one removed to have checked as I had noticed that one of my hubs although not hot was a little warm while the other was cold..... had it inspected by someone who knows a heck of lot more about bearings than I and they indicated the colour of the grease and the wear on the bearing indicated it wasn't going to have lasted long. It showed more indication of wear than the old bearing it had replaced that had been on the trailer for more than 5 years and repacked each year.
Although most of the big name bearing companies such as Timken and SKF do have their bearings made outside of NA these days they do have higher manufacturing specs and better quality controller than the smaller no name manufactures who's bearings can be had for real cheap on line.
The few dollars one saves on buying cheap no name bearings and seals isn't worth the potential trouble and possible vacation time interrupted due to issues with them.
