Hmmm this is really not true... Damn, I hate when Bill talks all this engineering bluff to pump the general audience.
All these other companies mentioned here DO provide these types of bearings and even if he said that the bearings are not approved by NAVAIR at a component level, they are found in thousands of components (jet engines, engine starters, landing gears, APUs, virtually every turbomachine power output shaft that is flying out there in the field) that are in fact certified and approved by NavAir. Thats why those companies trade in the big boards.
We need the facts right! This is a development company and we are willing to accept the risks.
