ABSTRACT:
A bearing unit includes a bearing body, a track rail and rolling elements. The bearing body is slid along the track rail through the rolling elements. A non-loaded rolling element rolling groove is formed on the bearing body in the longitudinal direction thereof by cutting a portion of the bearing body. The non-loaded rolling element rolling groove is covered with a cover, thereby forming a non-loaded rolling element rolling passage for recirculating the rolling elements which roll through the area between the bearing body and the track rail. A retainer may be provided between the bearing body and the track rail. The retainer has a guide surface for guiding the rolling elements rolling through the area between the bearing body and the track rail and preventing the dislocation of the rolling elements.
