Abstract
In order to provide a linear guide system having rolling grooves on both sides and an integrally formed rack, which can be used with either a guide rail or sliders fixed and in which the direction of the deflection of the rail with its self-weight is different from the direction of vibration caused by movement of the rack, rack teeth are integrally formed in one of the side surfaces of the guide rail on which rolling grooves for rolling members are formed so that the direction of the tooth traces of the rack teeth is orthogonal to the direction along which the rolling grooves for the rolling members of the guide rail are formed. Accordingly, vibration of the rack does not overlap with the deflection of the rail, thereby producing good effects on prolongation of the life of the rack, prevention of the noise and improvement of precision in positioning. Note that, this system can be used both with the rail fixed and with the sliders fixed.
