A wear detection method and system for a linear actuator such as a pneumatic cylinder, a hydraulic cylinder, an electric cylinder or the like. A physical amount detection sensor 9 is mounted on a linear actuator in which a push-pull member connected to a rod 2 pushes and pulls a pressure-receiving object while applying a lateral load in a direction different from the linear movement direction. An external force that is generated between a tube and the mounting member when the pressure-receiving object is pushed and pulled is detected by the physical amount detection sensor 9 and compared with standard external force data, which was detected in a state without abnormalities and stored in a computation/storage/determination processing device 10, to computationally determine whether the linear actuator is in a normal state or an abnormal state.
A wear detection method for a linear actuator that comprises a rod capable of moving linearly inside a tube mounted on a mounting member, and that pushes and pulls a pressure-receiving object while a push-pull member connected to the rod applies a lateral load in a direction different from the linear movement direction, the wear detection method comprising:
