FIELD: mechanical engineering; manufacture of bearings for automobiles.
SUBSTANCE: proposed ball bearing includes outer race 1 with two raceways, inner race consisting of two rings 2 and 3 with one raceway in each and two rows of balls 4 located in cages; balls are 4 are engageable with raceways; inner and outer sectionalized races have permissible deviation from nominal sizes of diameter in outer 
and inner 
raceways and distances in outer 
and 
between raceways which are measured in sections corresponding to nominal contact angle 
in bearing; balls have deviation from nominal diameter 
or races have excessive deviations of said sizes of raceways under conditions of shift of point of contact in outer 
and in inner 
and coincidence of signs of 
and 
. Method of measurement of deviation of contact angle 
from nominal consists in measurement of deviations exceeding sizes of raceways, determination of parameters of shift of 
and 
and estimation of deviation of contact angle which includes calculation of nominal radial clearance 
, half-difference of contact angles 
at axial and radial loading of ball bearing, measurement of axial clearance S, radial clearance P, contact angle 
at axial loading and comparison of results with nominal magnitudes.
EFFECT: enhanced durability due to reduction of deviation of contact angle from nominal magnitude.
