CONDITIONS<br />
Oil lubrication with corrosive environment<br />
Highly corrosive<br />
materials<br />
The operating conditions Of each application<br />
decide the choice of materials to be used in<br />
the bearing.<br />
The table below indicates materials currently<br />
used in various applications.<br />
NOTES FOR TABLE<br />
(1) The application may satisfy 1 of these 3<br />
conditions.<br />
(2) Metallic cages, depending on the application,<br />
may be silver plated to improve friction<br />
characteristics.<br />
(3) This table is not limiting <strong>and</strong> more variations<br />
exist. Our metallurgists are oonstantly developing<br />
new materials.<br />
N.dm Product of rotation speed in rpm <strong>and</strong><br />
meam diameter of the bearing in mm.<br />
A- : Operating temperature °C.<br />
Pmax Maximum Hertz stress in the contact between<br />
rolling elements <strong>and</strong> raceways.<br />
