Zusammenfassung:	A method for monitoring a linear guide with a carriage that can be displaced along a rail on a rolling contact formed from roller bodies rolling on running tracks using a sensor device for detecting a damage state of the rolling contact is provided. In order to provide a simple damage monitoring that can also be carried out for small computational units in short times and with very economical sensor devices, using the sensor device, an oscillation time signal is detected, an envelope curve demodulation of the oscillation time signal is carried out from the oscillation time signal, and a resulting magnitude is determined according to a constant-component determination as a characteristic value that increases with the damage state, and a damage state is recognized when the characteristic value exceeds a specified threshold value.
