Claims

[Scope of utility model registration request]

A track rail having rolling grooves formed in the longitudinal direction on the upper surface and both side surfaces, and transfer grooves formed in the longitudinal direction on the inner circumferential surface corresponding to the rolling grooves of the track rail, and with the rolling grooves. A bearing body having a ball return hole penetrating through both sides of the bearing body in an adjacent portion separated by a predetermined distance, and a circle that is attached and fixed to both end faces of the bearing body and that communicates the rolling groove and the ball return hole. It consists of a lid body having an arc-shaped ball reversing path, a rolling groove of the track rail, a rolling groove and a ball return hole of the bearing body, and balls arranged and held in the ball reversing path of the lid body, In a linear motion bearing in which the bearing body is straddled over a sliding chamber via the bow/l<, two plates divided by a plane including the center line of the reversal locus of the balls are joined together. A reversing member is configured to form a ball reversing path and a grease reservoir gap on the inner diameter side of the ball reversing path. A linear motion bearing characterized in that it is fitted and combined with a lid body so as to communicate with each other.
