PURPOSE: A device for measuring the inner/outer diameter of a bearing is provided to measure the inner diameter or the outer diameter of the bearing in a short time and to accurately measure the inner diameter or the outer diameter of the bearing by measuring the displacement of the bearing with six measuring balls. CONSTITUTION: A device for measuring the inner/outer diameter of a bearing includes a base plate (110), a main frame (130), an inner/outer diameter measuring member, and a bearing supply member (120). The main frame is fixed to the base plate. The inner/outer diameter measuring member is fixed to the main frame to be spaced from the base plate. Six or more measuring balls (200) which are in contact with the inner/outer surface of the target bearing are arranged at equal intervals. A displacement sensing member senses the displacement of the bearing caused by the measuring balls so that the inner/outer diameter of the bearing is measured. The bearing supply member supplies the target bearing to the inner/outer diameter measuring member. |
