Provided are a bearing track groove measurement device and a bearing track groove measurement method, which are capable of performing highly-precise measurement and are capable of performing measurement without destructive inspection even when a workpiece is an inner race or an outer race of a large-sized bearing. A displacement sensor turns about a groove center of a horizontal cross-section of a bearing track groove to detect a radius value corresponding to a dimension from the turning center to a groove bottom surface. Turning angle detection means detects a turning angle of the displacement sensor. Calculation means calculates a profile waveform of the bearing track groove based on the radius value detected by the displacement sensor and the turning angle at the radius value detected by the turning angle detection means. |
