Experiments have been carried out on a high speed, precision, angular contact, thrust-loaded ball bearing to determine the effect of reduced lubricant flow rate on the minimum load required to prevent gross skidding. The effect on power consumption in the bearing was also monitored. The results showed a significant reduction in minimum load, down to as little as 20-30 percent of its original value, for a range of speeds from 5000-20,000 rpm. Computer simulation of the bearing indicated that as the oil supply was reduced there was a reduction first in cage drag, then in pocket fraction, and only at very small flow rates was there any evidence of starved elastohydrodynamic lubrication. 6 refs.
