Oil and fluid grease
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-
component 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
