FIELD: measuring raceways of races of double-row radial thrust bearings at selective assembly. SUBSTANCE: device includes coaxial fixed and movable taper guides and measuring head. Two rows of balls : upper and lower rows are secured in cages for engagement with taper guides. Located between guides for self-adjustment and engagement with both rows of balls is additional guide limiting motion of balls in direction perpendicular to direction of measurements. Accuracy of device may be measured by means of standard measuring devices. EFFECT: enhanced accuracy of measurements. 6 dwg
