Abstract : The paper studies slide bearings made of nonmetallic materials with lubrication of 42% nitric acid. Studied were bearings made of antifriction graphite, fluoroplastic-4 and slag microcrystalline glass at specific pressures of 1.0-9.0 kg/sq. cm. and a journal circular speed of 1-8.3 m/s. Removable journals were made from acid-resistant chrome-nickel austenite-ferrite stainless steel EI-654. The microgeometry of the friction surfaces was determined on the 'VEI-Kalibr' profilometer-profilograph and the MIM-7 microscope.
