I need 806037 Deep Groove Ball Bearing 40x92x23mm in this size for use as motorcycle main bearings. The stock are a very tight fit on the crank and in the cases. As delivered, the bikes ran these lubricated by splash in a wet sump environment. The bikes made about 50BHP and rarely exceeded 7000RPM. My business is performance. We need them to handle 100HP at up to 11000RPM. Stock Yamaha have coped with 140HP up to 12000RMP - where they spin their outer races in the cases. No clips, but an oiling groove would be okay. Rollers and/or ceramic preferred. How I wish the OD was 90mm; it would open up a lot of possibilities. Looking for ten lot to start.
