A guide device having, a guide rail and a runner, which engages at least in part in the guide rail and is guided in a linearly movable manner in the guide rail via a recirculating ball bearing. The balls associated with the recirculating ball bearing are arranged in at least one ball row and guided in at least one ball raceway. The balls associated with a ball row are each guided in a ball raceway composed of two partial ball raceways. The first partial ball raceway is formed in the runner and extends along a runner longitudinal axis. The second ball raceway is formed by a guide groove, formed on the runner and extends along the runner longitudinal axis, and a guide rail guide groove, opposite the runner guide groove and formed on the guide rail.

The slider assembly (10) comprises a first support (12a) and a second support (12b), a first guiding element (14a) arranged on the first support (12a) and a second guiding element (14b) arranged on the second support (12b), wherein the first guiding element (14a) is configured to receive a first rail (104a) and the second guiding element (14b) is configured to receive a second rail (104b), such that the slider assembly (10) is slidably arrangeable on the first rail (104a) and the second rail (104b). The slider assembly further comprises a tolerance compensation element (18), which connects the first support (12a) and the second support (12b), such that at least a part of the first support (12a) and at least a part of the second support (12b) are spaced apart from each other, thereby allowing a relative movement of the first support (12a) and the second support (12b) with respect to each other.

Provided is a sensor mounting member and a sensor mounting method for easily fixing a sensor of a type among various types to a track rail of a rolling guide device in one operation. The sensor mounting member includes: a sensor holding portion configured to cover the sensor so as to hold the sensor between a top surface of the track rail and the sensor holding portion; and a pair of leg portions, which are formed at both ends of the sensor holding portion, respectively, and are configured to sandwich the track rail from both sides in a width direction of the track rail while being elastically deformed. Further, along with sandwiching of the track rail by the pair of leg portions, the sensor holding portion presses the sensor onto the top surface of the track rail.

A profiled rolling apparatus for lowering rolling resistance in track-guided, load-bearing movement applications. The rolling body, as part of a track roller, cam follower, caster wheel, or the like, has a radial groove (e.g. a V-shape with some internal angle) on which a non-linear profile is implemented. Profiles for various embodiments may be, but are not limited to, circular arcs, polynomials or other mathematical functions, or made up of multiple shorter linear and/or arc segments, creating a convex or concave contour on either side of the groove. Such crowning profiles may additionally or alternatively be implemented on the guiding track.

A magnetic bearing device and a positioning system which includes the magnetic bearing device are provided. The magnetic bearing device comprises a stator and a moving member which are formed from a coil device with at least one coil body, magnets, and/or flux guide members, where the moving member is movable relative to the stator along a direction of motion and the stator and the moving member are configured such that a magnetic force can be exerted upon the moving member when electrical energy is applied to the coil device to form an air gap between the stator and the moving member. The coil device is arranged exclusively in the stator and the extension of the moving member in the direction of motion is smaller than the extension of the stator in this direction. The extension of the stator corresponds to the length of the at least one coil body.

A device and a method for detecting states of a linear guideway including a sliding block and a slide rail are provided. The device includes a sensor located at a position corresponding to a side surface of the slide rail, and an analysis processer communicated with the sensor. The sensor detects the vibrating of the slide rail to generate a sensing signal. The analysis processer compares the sensing signal with at least one threshold, to determines occurrence of abnormalities. Therefore, the sensitivity for detection may be increased.
