Abstract : This report describes the evaluation work performed on oscillating bearings of both plain journal and self-aligning types. The bearing substrate material included cermets LT-1B and LT-2 and alloys F-48 and Rene 41. Lubricants receiving extensive evaluation were a cla silver-palladium alloy, molybdenum disulfide used in cavities, and bonded molybdenum disulfide. Results include those from friction and wear evaluations, radial load capacity tests on plain journal bearings, and axial and radial load capacity tests on self-aligning earings. The bearing specimens had a nominal diameter of 1/2 inch. The friction and wear tests were made at an oscillating frequency of 31 cpm, at temperatures generally ranging from -90 to 1750 F, and at pressures generally ranging from 10 to the -6th power to 10 to the -5th power mm Hg. The projected bearing load was in the range of 4,400 to 12,000 psi. (Author)
