PROBLEM TO BE SOLVED: To provide a runout measuring device capable of accurately obtaining a maximum phase of a runout in synchronization with rotation required for attaching a balance weight.SOLUTION: A runout measuring device for rolling bearing comprises: a fixing base for fixing an inner ring of a rolling bearing to be measured; a weight member that applies a measurement load to an outer ring of the bearing; and runout quantity detection means that detects a quantity of runout of the outer ring. Analysis means takes in a displacement signal in synchronization with a rotation phase among the quantities of runout that are displacement data detected by the runout quantity detection means, and calculates a magnitude of runout and a maximum phase of runout of the outer ring on the basis of the signal data.SELECTED DRAWING: Figure 1 |
