Abstract:
Sleeve bearing materials and lubricants were tested on an hydraulically operated apparatus, which simulated the loads and motions of typical airframe bearings. Beryllium-copper alloy 25 provided excellent bearing properties for grease-lubricated applications requiring high stresses and low wear rates. Hardened M-50 tool steel shafts provided excellent wear and fatigue resistance for use with beryllium-copper bearings. The lubricating capabilities of MIL-G-81322 grease were similar to MIL-G-3287 grease, which it replaced, but provided improved resistance to galling. No beneficial effect resulted from the presence of MoS2 in greases used to lubricate molybdenum-containing bearings. Author
