The present invention provides a linear sliding device. The linear sliding device can prevent the movement by removing a contact gap while bearings are rolled on and in contact with a linear guide rail and can be operated softly without noise by reducing the force of kinetic friction. The linear sliding device according to an embodiment of the present invention comprises: the linear guide rail having a gutter longitudinally opened upward, and bearing guide grooves formed on vertical walls of both sides facing each other inside the gutter at a same height; a slider positioned on the upper side of the linear guide rail; first and second inner horizontal rotation bearings positioned on the lower side of the slider to linearly move the slider while rolling along the bearing guide grooves; bearing support bolts inserted to the first and second inner horizontal rotation bearings and screw-coupled to the slider so as to support the rotation of the first and second inner horizontal rotation bearings; and one or more stop ring having a diameter same as or smaller than an inner ring of the first and second inner horizontal rotation bearings and determining the fixed position of the bearing support bolts after being inserted to and screw-coupled to the bearing support bolts. |
