A minimal lubrication system operating on ultra low oil consumption. Compressed air is used as a carrier. Metered oil, suitably mixed with air, is conveyed in non atomised state to the lubrication point. AZETA AIR MIX is especially recommended for lubrication of high speed rolling contact bearings on spindles, electro-spindles and of rotating bushes of lathes with sliding headstock. For linear guides, the continuous flow keeps clean the tracks and races of balls or slides, as well as the contact races of rolling contact bearings.
