Abstract: Disclosed is a linear guiding system (1) comprising at least one guide rail (2), at least one guide carriage (3) that is supported on the guide rail and can be moved therealong, and a device (5) for measuring a distance traveled by the guide carriage relative to the guide rail and/or determining a position of the guide carriage relative to the guide rail. The measuring device (5) encompasses a measuring rule (10) and a measuring head (21) that is provided with at least one sensor for scanning the measuring rule (10). The measuring rule extends in the longitudinal direction of the guide rail while being arranged along or on a surface (2.1) of the guide rail (2) facing the support zone (40) of the guide carriage (3). A cavity (25) for accommodating the measuring head is embodied in the guide carriage. Said cavity (25) is configured entirely or partly outside the support zone (40) while the measuring head (21) is disposed entirely or partly in the cavity (25) and entirely or partly outside the support zone (40).

Abstract: In order to keep to a minimum the expense, in particular, the expense for the formation of reference surfaces, with a linear guide system with two guide rails (10, 12) and, respectively, two carriages (30, 32), it is proposed that a spacing plate (20) is welded, adhered, or is attached in another manner, such that the reference marks of the guide rails (10, 12) can further form the reference for the system. As a further feature, it is proposed to weld, adhere, etc., a further spacing plate (60) between the carriages (30, 32).

Abstract: A linear movement guide for translatory relative movement, without lubricants, of objects to be moved along a guide axis (1) comprises a rail (2) on which at least one carrying surface (10), which extends parallel to the guide axis, is provided, and a carriage (8) which comprises at least one loop (9, 45) of roller bodies, wherein the loop (9, 45) of roller bodies is a closed loop for the circulation of roller bodies. The roller bodies, which are arranged in the loop (9, 45) of roller bodies of the carriage (8), during a relative movement between the carriage (8) and the rail (2), for the transfer of loads, run through a carrying area of the loop of roller bodies and in this process are positioned both against the carrying surface (10) of the rail (2) and against the carriage (8), at least essentially free of any organic lubricants.

Abstract: A linear motion guide for mounting and longitudinally guiding machine parts, in which a first guide element provided to be fixed to a machine part is guided by a plurality of rolling elements along a longitudinal movement axis with respect to a second guide element, likewise provided to be fixed to a machine part, for this purpose each guide element has a groove-like recess running parallel to the longitudinal movement axis, boundary surfaces of the recess in each guide element are provided as rolling surfaces for the rolling elements, the rolling elements are arranged one after another in one or more rows in at least one cage between the two guide elements, the cage is provided with at least one first positive guide, the cage with its first positive guide being guided by second positive guide fixed to the guide elements, each second positive guide being arranged only on one of the guide elements and being fixed in position relative to the latter.

Abstract: A linear displacement guide, comprising a guide rail and slide that is supported via roller elements on the guide rail. The guide rail contains a groove extending essentially in longitudinal direction and through openings that can be covered for fastening the guide rail, wherein at least one of the through openings is located in the groove region. The linear displacement guide is provided with a covering means to be arranged on and secured to the guide rail to permit a simple and tolerance-insensitive assembly. The invention suggests securing the covering means, designed as cover band (4), on the guide rail. The cover band should comprise a center section (20) and two adjoining clamping legs (21), which are angled relative to the center section (20), wherein the cover band (4) can be fastened to the guide rail (1) by fitting the two clamping legs against the side walls (15) of groove (14).

Abstract: A carriage for a linear guiding device, designed to be arranged on a rail. The carriage includes a center section and two legs that each join the center section, thus providing the carriage with an essentially U-shaped design. The carriage further includes a support region as well as two deflector channels that connect the return channel and the support region, sleeve-shaped guiding elements that are arranged in recesses of a basic body of the carriage, in the return channels. Plastic material is poured in part or totally around one of the two ends of at least one sleeve-shaped guiding elements in order to secure it inside the recess. The sleeve-shaped guiding elements are each provided with centering elements on their outside surfaces, which elements are used to determine the position of a guiding element.

Abstract: A slider of a linear-movement guide, which is provided in a rail-supported arrangement, has a center segment and two legs that respectively adjoin the center segment so that the slider has an essentially U-shaped cross section, and a recess that extends parallel to the axis of longitudinal movement. The slider further has at least one roller-body track in the region of the two legs, with each roller-body track having a return conduit, a support zone and two diversion conduits that connect the return conduit and the support zone to one another. At least one leg has at least one groove, and an insert for diverting the roller bodies is inserted into the groove.
