Bearing forward and reverse detection device

The utility model relates to a bearing front and back detection device, which comprises a base and a detection table arranged on the base in a protruding manner, the detection table is connected with a profiling column unit used for sleeving a bearing, the outer diameter of the upper end of the profiling column unit is matched with the inner diameter of the bearing to be detected, the profiling column unit is provided with a detection unit, the bearing is sleeved on the profiling column, and the bearing is detected by judging whether the profiling column unit is in close contact with the detection unit or not. And the detection unit is connected with the control system and the alarm unit. The device at least has the following beneficial effects that the device detects the forward and reverse directions of the bearing by combining compressed gas and the pressure switch, and is ingenious in design and high in practicability. 本实用新型涉及一种轴承正反检测装置，包括，基座、凸设于所述基座上的检测台；所述检测台上连接有用于套置轴承的仿形柱单元，所述仿形柱单元的上端外径与待检测轴承的内径相互配合，所述
