Yes, go to a Bearings and Drives type of industrial supply place and get quality bearings, Timken or Toyo are probably the two best. Last Timkens I bought for a trailer were USA made, both races and bearings.
Best you can do at an auto parts place is Mexican made bearings from NAPA. Everything else is China made and those are pure junk, but all too commonly used.
