WebA lubricant can be in liquid (oil, water, etc.), solid (graphite, graphene, molybdenum disulfide), gaseous (air) or even semisolid (grease) forms. The liquid lubricants can be classified based on the base oil to synthetic/semi … WebThe liquid lubricants, however, maintain themselves as liquid films between the surfaces, upon which the bearing floats. The frictional resistance is then wholly in the fluid. Even when lubricants are used the friction, i.e.the resistance to motion offered by the opposing surfaces, is considerable.
