Abstract: A linear guideway includes a rail, a slider disposed on the rail, and a load passage formed between the rail and the slider. The slider has two non-load passages penetrating through two opposite end surfaces of the slider. Each of two ends of each non-load passage is provided with a force sensor. Two end caps are disposed on two opposite end surfaces of the slider respectively and each have two circulation grooves. Each circulation groove is connected to an end of the load passage and an end of the non-load passage to form a circulation channel for balls to move therein. As a result, the linear guideway of the present invention employs force sensors to sense the force-receiving state of two ends of the non-load passages when they are impacted by the balls, so that it can be determined that if the balls have an abnormal pressing state.
