|3. Basic static load rating and safety coefficient| |1)||Basic
static load rating| bearing may sustain a local deformation
permanently when exposed to an excessively high static load or
impact load. If the permanent deformation is beyond a specific
extent, smooth rotation is imposed. The static load under which
contact surface pressure working between the rolling element and
raceway may generate the following sizes of contact stress is
called the basic static load rating and is used as a reference
to determine a high load. |2)||Static equivalent load| | The
static equivalent load is a virtually calculated load, under
which contact stress of the same degree as generated under
actual loading conditions would occur between the rolling
elements and raceway in the section exposed to the maximum load.
It is calculated by means of the equivalent static load
calculation equation, using the load factors listed in the
tables. | A safety coefficient is designated, based on empirical
data, so as to ensure safety in rela
