Thanks for the quick replys Patrick, always helpful!!

The bearing size is 14mm x 5mm x 5mm, which is REALLY big by 36mm motor standards. . . Helps with side loads and impacts (not than these motor ever actually take any impacts.... ) but is a little hard on the balls and race at really high RPM.

The bearings are rated for 75,000 RPM continuous, 100,000 short term.

Still a 2 pole design.
