PROBLEM TO BE SOLVED: To provide a stand-out measurement method capable of measuring a stand-out before assembling an angular ball bearing.;SOLUTION: An inner ring measurement value showing an axial direction positional relation between an outer ring tool 11 and an inner ring workpiece 5 is determined by combining an inner ring workpiece 5 with an inner ring measurement tool set 10 by using a master reference value obtained by combining an inner ring master Mi with the inner ring measurement tool set 10 including an outer ring tool 11 as a reference. Further, an outer ring measurement value showing an axial direction positional relation between an inner ring tool and an outer ring workpiece is determined by combining the outer ring workpiece with an outer ring measurement tool set by using a master reference value obtained by combining an outer ring master with the outer ring measurement tool set including the inner ring tool as a reference. A stand-out δ is determined on the basis of a correction value for correcting an error caused by the use of the obtained inner ring measurement value and outer ring measurement value, a master stand-out, the inner ring measurement tool set 10 and the outer ring measurement tool set.;SELECTED DRAWING: Figure 6;COPYRIGHT: (C)2016,JPO&INPIT
