An oil shutoff test was conducted on a 35 mm bearing with silicon nitride balls. The time to bearing failure was 90 sec compared to 45 sec for an M-50 steel bearing which was similarly tested. This result compares favorably with the 1.74 factor was predicted by an analytical model. Post-test inspection found the silicon nitride balls with minor surface distress compared to the extreme spalling of the M-50 balls. Author
