High Temperature Lubrication of Electric Motor Ball Bearings
Abstract
The 5-year program just completed was aimed at the development of greases and ball bearings suitable for lubricating electric motors at bearing temperatures from -40 to 150 deg C. Research activities of this Laboratory were coupled with those of a number of leading industrial manufactures of electric motors, ball bearings, and lubricants by means of an industrial cooperative committee of the Bureau of Ships. As a result of this development program, recommendations were made to the Bureau of Ships upon which was based the recent specification MIL-G-15719 (Ships). New or improved methods of laboratory testing of greases and for bench testing of motor ball bearings were evolved for use at 150 deg C. Nine newly developed greases (all of which are now commercially available) were investigated and tested jointly.
