Provided is a usage status management system for axle bearings that is particularly useful in a railroad vehicle having no current collector or travel drive source, and with which, with a simple configuration, it is possible to manage the usage status of axle bearings. Mounted on a railroad vehicle (2) are a GPS receiver (12) and a communication device (14) for wirelessly transmitting the position information received by the receiver. A usage status management device (18) is provided on the outside, and the usage status management device (18) is provided with a travel distance calculation means (21) for calculating the distance traveled by the railroad vehicle (2) on the basis of data transmitted from the communication device (14) of the railroad vehicle (2). The railroad vehicle (2) is also provided with temperature sensors (13) for measuring the temperature of axle bearings (3), and the measured temperature is transmitted to the usage status management device (18) by the communication device (14). |
