Abstract: A monitoring device monitors a forming machine (target device). The forming machine includes a housing, a bearing attached to the housing, and a shaft placed radially inside the bearing. The monitoring device includes a plurality of heat flux sensors and a detector. The heat flux sensors are provided on the radially outer side of the bearing and spaced from each other in the circumferential direction of the bearing. The heat flux sensors output a signal corresponding to heat fluxes through faces thereof on the bearing side and faces thereof on the other side. The detector detects a load applied radially to the shaft or bearing, based on the output from the heat flux sensors.
