Abstract

Long-term lubrication of highly loaded lubricating areas or surfaces, such as in very high speed medical and/or dental equipment, is obtained by applying a synthetic film, for example composed of poly(fluoroacrylic acid methyl ester) onto the sliding/moving surfaces, along with a polar oil having high lubricity. Anti-microbial agents can be added to the synthetic film. A pre-coat of molybdenum sulfide (MoS.sub.2) can be provided for the synthetic film. Stationary surface abutting the sliding/moving surfaces, such as cages for ball-bearings, preferably composed of a phenol resin, can function as a reservoir for the anti-microbial agents and the oil.
