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-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.
