    I think this question is for ball bearing
    For roller bearing the power to be 1/3

    For ball bearing: p=3
    For roller bearing: p=10/3
    p is the exponent of life equation:
    L=(C/P)^p

    This is for ball bearing only.. for roller bearing it is 1/3

    L=(C/P)^3
    L=rated life
    P=equivalent radial load
    C=dynamic load capacity
    So load varies inversely as cube of load

    L10= (C/P)^p
    Where, L10 - Basic Rating Life
    P- Load
    C- Load Rating
    p- for ball bearing 3
    - for Roller bearing 3.3333.

    The total number of revolutions before a failure occurs is called the basic rating life. The bearing life of individual bearings varies considerably, even if they are of the same size, same material, same heat treatment and are under the same operating conditions.
