From their website: We carry an in house inventory valued at over $10,000,000 that includes over 14,000 different product sizes, sourced from Major Brand Name factories across the globe. We also carry an extensive Value Priced range of bearings and power transmission products to service the price conscious customer.
So they are made all over the world. But their website looks impressive. I suppose I’d trust them as much as any other.
I once was faced with finding a supplier for bearings when our Japanese source was not able to deliver. I found some in Germany ($$$$), and two in China ($). Our engineering department requested samples from both China sources for testing. One passed the torture test with no problem, the other failed. I suppose the country of origin is not as much a determining factor as we would think it is (speaking on the quality issue only).
