The technical knowledge that comes 
to you from SKF engineers is 
as it is the sum of the data gathered by 
organizations in all industrial countries. 
This fund of engineering information we bring to the fabrication of all 
products bearing the mark SKei a,,an( i the operation of those industries 
which we are requested to supervise. In order that complete reliance may 
be placed in the endorsement expressed by the mark SKi^it is neces- 
sary not alone that we control and supervise each step in the manufacture 
of a product but also its final installation. 
Because every effort is made to assure the most satisfactory use of prod¬ 
ucts marked SICI 3 ^ we welcome requests for information concerning 
their proper application and maintenance. 
Manufacturers should feel that this technical knowledge is always avail¬ 
able. You are urged to use it freely without any sense of obligation.
