Assurance of lubricant supply in wet-lubricated space bearings [PDF]
, 1976 Conventional lubrication techniques appear to be satisfactory, but rigorous proof of meeting a ten-year life requirement is lacking. One approach provides additional lubricant only when commanded from ground control, while the other passively augments ...

Analysis of the Ball Load in Angular Contact Ball Bearings during Operations.
Journal of the Japan Society for Precision Engineering, 2001 Spindles used in machine tools, especially machining centers, must operate at high speeds with high stiffness and low temperature rise in order to achieve improvements in productivity and accuracy of the machine. Usually, preloaded angular contact ball bearings are used to satisfy these requirements.
