Abstract
A linear guide table system includes a pair of linear guide apparatuses connected in parallel to each other by a common table fixed to upper surfaces of sliders of the pair of linear guide apparatuses. Each slider of the pair of linear guide apparatus has an inverted L1-shaped cross section and has side walls. In each slider, one ball rolling groove is formed in a lower portion of an inner surface of one of the side walls, and one ball rolling grooves is formed in an upper portion of an inner surface of the other of the side walls thereby to form the ball rolling grooves asymmetrically with respect to a vertical plane containing a longitudinal axis.
