TMB bearings

Anyone know of a vendor of TMB bearings?  They are heat treated and claim to offer 2 times the life of standard ball bearings.  

Thanks

TMB or thermo mechanical bearings are available from Japan with a lead time of approx 4 to 6 months.  Cost ?.  I'm evaluating using maximum duty bearings or BL series.  These bearings have 8 balls versus 7 for standard units.  They carry a higher load and somewhat lower rpm limit.  Cost is $35 versus $20 for a standard 6305 bearing.  I bought and received a set of bearings which I come to find out are made in China and I'm now considering not using them.

These are wheel bearings?

I'm not sure they are available as wheel bearings.  My application was the manual gearbox.  TMB seems like the way to go but $ and availability are in ?.  Still evaluating the BL series.  The issue with them is they have an extra ball bearing ( total. In order to put the extra ball in they have to cut a slot in the outer and inner race.  Significant thrust (lateral) force on the bearing can cause the balls to exert force against the slot causing premature failure.
