ABSTRACT:
An anti-friction bearing for linear movements comprising a bearing body (10) which is guided movable on a rail (12) in a longitudinal direction thereof. The bearing body has legs (18a, b) accommodating at least one part of the rail (12) between them and a web (20) connecting these legs (18a, b) in one piece. At least one rolling body cycle (A-D) allocated to each of the legs (18a, b) has one load-transmitting rolling body row (A1-D1) in engagement with one load-receiving running path (B13, D13) of the respective leg (18a, b) and with one running path (A12-D12) at one side face of the rail (12) said side face being adjacent to said leg (18a, b). The load-transmitting rolling body rows (A1-D1) are preloadable between the respective allocated paths (B13, D13; A12-D12) and this preload is adjustable by preloading means (30). The preloading means (30) are disposed in the range of the web (20) with a direction of effect substantially normal to the longitudinal direction of the rail (12) and substantially parallel to a connecting plane (VE1, VE2) of the two load-transmitting rolling body rows (A1-D1) lying at either side of the rail (12), and which are designed to upset the web (20) in this direction of effect.
