REPORT OF DRY RUNNING TWO 440-C HEAT TREATED STAINLESS STEEL ANNULAR BALL BEARINGS IN A HELIUM ATMOSPHERE AT 510 F TEMPERATURE

Technical Report ·
OSTI ID:4818823
The results of rotating a 440 deg C heat-treated air-melted stainless steel, full complement, annular ball bearing under 1l70 lb radial loading at low speed in a heliuim atmosphere at a temperature of 5l0 deg F are presented. The two test bearings were operated undcr load for l2l,400 revolutions at an average speed of 4 rpm. The test was terminated after the required time of 500 hr was attained. Photograpbs are presented which show the test bearings after removal from the machine. Data are presented in tables and graphs. (M.C.G.)
