Abstract
Provided is a motion guide device load measuring system that can accurately measure loads acting on a motion guide device in use. The load measuring system includes a position detecting unit (4) for detecting the position of a sliding member (12) relative to a track member (11) in a direction of relative movement, and at least one sensor (2a-2d, 3a-3d) for detecting the relative displacement of the sliding member (12) relative to the track member (11) in a radial direction and/or a horizontal direction. A calculating unit (6) calculates loads acting on the motion guide device (1), in association with the position of the sliding member (12), on the basis of position information detected by the position detecting unit (4) and displacement information detected by one or more of the sensors (2a-2d, 3a-3d).
