Going to do some trailer maintenance on my Dad's tandem axle trailer. Wondering if USA made bearings still exist?
Maybe they do, but chances are you are about 100 years out of date if you are looking for USA-made bearings.
"Made in the USA" can mean any part of a product. It might simply be the box it comes in.
Notice that the "Made in USA" tends to be printed on the box, not on the bearing.
Timken advertise as "made in USA" even thought they are also made in China, Romania, Indonesia, India, and Mexico. And in a couple dozen other companies. Regardless, they seem to be fine bearings.
Bearings are made everywhere and in every country. Stick with a known brand name if you want some sort of connection to quality. But be prepared to pay. The known name bearings are noticibly more expensive.
SKF are still top quality Swedish bearings - but they were one of the first to move a lot of their production to China - over 100 years ago. They also manufacture in Mexico and all over Europe....as well as in over 100 countries. I've never heard any knocks on their quality.
Same is true of FAG bearings from Germany.
NSK and NTN bearings used to be totally Japanese made. That's as good a statement of good quality as you are likely to find. No idea if it is still true. But their bearings are among the best.
When I was designing some heavy transmissions many, many years ago, the best big bearings that were affordable for manufacture were Czech made. A few years later - working in the hard drive industry - where bearing quality is one of the most important factors in the whole device - everyone in the industry was fightng to get the best bearings from Indochina area countries.
Read this. It seems well researched
In recent years, the demand for high-quality bearings has steadily increased due to advancements in various industries, such as automotive, aerospace, and heavy machinery. As a result, it's important to be aware of the top
