| 摘要 |
The invention relates to a bearing device in such linear actuators which comprises an elongated hollow profile rail (1), in which a slide member (2) can be moved backwards and forwards along flat guiding surfaces (8) in the hollow profile rail (1). In pairs, the guiding surfaces (7, 8) form an angle with one another. Between the hollow profile rail (1) and the slide member (2) slide bushings (9, 10, 11, 12) are arranged. By means of a flat face (13) these bushings in pairs abut against one guiding surface (7, 8) each and by means of a curved face (14) said bushings are arranged in a correspondingly configured seat (1 5, 16) in the slide member (2). |
