 We have bearings available from both Japan and China. We can specify which
country to use for any given application. However due to cost constraints
most of our distributors want to carry Chinese bearings.****

If you want Japanese only, please let me know what size you want and I will
see what I can do.****

Thanks****

Dynaroll in Sylmar is a large domestic manufacturer of quality bearings.  I
have included their chief engineer to hopefully steer us to one of their
distributors.****

Robi is involved with another local HAK group and is an all round nice guy.*

 Evaluation boards are a good source for projects.
