                                                The viscosity is an expression of a fluid’s  internal friction. Oils are
                                                classified in ISO VG viscosity classes from 2 to 3 200. NLGI grade 000, 00 and 0 greases
                                                are called fluid greases. Different types of oils are available, including mineral oils, organic
                                                oils and  synthetic oils. A compatibility check is recommended prior to using any oil with
                                                SKF lubrication systems.















                                                Grease
                                                Greases are consistent lubricants (NLGI grade 1–6). They are soft to hard, triple-compo-
                                                nent mixtures of a base oil as the lubricating fluid, a thickening agent and additives.
                                                In most instances, greases of NLGI grade 1 up to 3 are suitable for use in a lubrication
                                                system.  A compatibility check should be made prior to using any grease with
                                                SKF lubrication systems.
