application 

 

All products from SKF LUBRICATION 
SYSTEMS GERMANY AG must only be 
used in accordance with regulations 
and according to the information 
contained in the operating instructions 
of the respective product. 

 
We would particularly like to point out that 
hazardous materials of all types (especially 
materials classified as hazardous according to 
EU directive 67/548/EU Article 2, Paragraph 2) 
require agreement and the expressed written 
consent of SKF LUBRICATION SYSTEMS 
GERMANY AG to pour these substances into 
SKF products, transport them and/or distribute 
them. 
 
All products manufactured by SKF are not 
permitted for use with hot gases, liquefied 
gases, gases under pressure in solution, steam 
and those liquids with a vapour pressure at the 
maximum permitted temperature more than 0.5 
bars above the normal atmospheric pressure 
(1013 mbar). 
 
Except for the specially listed products, SKF 
products are not permitted for use in areas 
where there is a danger of explosion. 
 
 

 
 
 
 
The SKF minimal quantity lubrication system 
L

UBRI

EAN

®

 Vario, or MQL system for short, was 

designed for the internal lubrication of cutting 
tools for machining. Internal lubrication is 
defined as the direct feeding of lubricant 
through tool spindle or tool revolvers and the 
tool directly at the point of friction between the 
tool tip and the component.  
 
Other use or use that goes beyond this is 
considered improper use. SKF assumes no 
liability for any damages possibly resulting from 
improper use.  
 
If you also want to use the MQL system

 Vario for exterior lubrication tasks, 

you should consult us about this first. 
 
The SKF MQL system L

 Vario can be 

used for the original fitting of machine tools as 
well as for the retrofitting of machine tools with 
existing cooling lubricant supply. The system 
operates according to the principle of internal 
lubrication, making it suited for connecting to 
tools with very small cooling channel diameters. 
A consultation with SKF is necessary.
