Abstract
A linear motion system includes a guiding member, a moving member, a plurality of rolling members, a controller, a preload sensing member and a preload adjusting module. The moving member is slidably disposed on the guiding member, and the moving member and the guiding member together form a circulation path. The rolling members are accommodated in the circulation path. The preload sensing member is disposed on the moving member. The preload sensing member detects a preload value generated by the rolling members and applied to the moving member, and outputs a detecting signal to the controller. The preload driver and adjusting assembly of the preload adjusting module are disposed on the moving member. The controller controls the preload driver to adjust the adjusting assembly according to the detecting signal to adjust the preload value to a preset value.
