  • CONTENTS Precision Technology Inside - FAG bearing

    FREQUENCY CALCULATION. One can determine bearing vibrations on the basis of structural sound level tests which allow to make conclusions about surface quality (waviness) in the bearing rings and balls. Low structural sounds are the result of high smoothness as well as low friction, and predict high performance and long life expectancy of the bearing.
