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. Besides, a first end cap and a second end cap are disposed on two opposite end surfaces of the slider respectively. The first end cap has two first circulation grooves. The second end cap has a circulation member and a seal sheet. The circulation member has two second circulation grooves. The load passage, non-load passage, first circulation groove and second circulation groove collectively form a circulation channel for balls to move therein. A force sensor is disposed between the circulation member and the seal sheet. As a result, through the rigidity difference between the first and second end caps accompanied with the force sensor, it can be determined that if there is an abnormal circulation state.
