A Collision Bearing within a channel means, expressing the universal physical principle of collision. An assembly of two weight-bearing bearings, in two embodiments, for the purpose of moving objects. A slide plate must be attached to the support body of the bearings, whose width is in sliding contact with the inner channel walls, to align the motion of the bearings along the channel. This channel having a flange member, which retains the Collision Bearing within the channel. These two functions, rolling and sliding, simultaneously, demonstrates the universal physical principle of collision being claimed, and places the Collision Bearing in the category of a basic machine in the field of mechanics, as is for example, the nut and bolt. Impact pads are attached to the end walls of the bearing support body as a necessary component part in protecting this body.

A table device including: a first base including a first reference surface; a second base including a second reference surface, and movable on the first reference surface in a direction parallel to a first axis; a first bearing member provided to the second base, and forming a gas bearing between the first bearing member and the first reference surface; a second bearing member provided to the second base, apart from the first bearing member relative to a direction parallel to a second axis perpendicular to the first axis, and forming a gas bearing between the second bearing member and the first reference surface; and a table movable on the second reference surface. A distance between the first bearing member and the second bearing member is longer than a dimension of a moving range of the table relative to the direction parallel to the second axis.

An actuator includes a cylinder sandwiched between a fixing plate fixed to the other end surface of a supporting plate together with a servomotor and a bearing housing, a ball screw shaft having one end protruding into the cylinder through through holes of the fixing plate, a slide block screwed with one end of the ball screw shaft in the cylinder, a cylindrical-shaped piston coupled to an end of the slide block and reciprocatably located in the cylinder, linear motion bearing units located inside the bearing housing to movably support the piston, and linear motion bearing units located in the cylinder to movably support the slide block.

A roller guide wheel contains a single set of spherical bearings and is constructed with a precision outer race machined into the guide wheel interior and an inner race formed by the surfaces of two conically-tapered set screws that affix the roller guide wheel within a housing made part of a stage slider. The roller guide wheel, which contacts a rail on one side of the stage body and exhibits a non-nutating axis of rotation, serves as way for the translating slider. The way on the opposing side of the slider is a set of v-groove contacts that make sliding contact with a rail on the corresponding side of the stage body. A flexure is machined into the slider permitting preload of the slider contacts points with the rails. The stage geometry permits a large slider through-hole and the use of alternative way mechanisms with the roller guide wheel.

A plastic sliding component for mounting without lubricant in a sliding bearing is proposed, having a moulded part which is manufactured from plastic and has a sliding face for movably guiding two bearing parts relative to one another. An electric function circuit with a sensor function for acquiring an operating parameter is arranged on the moulded part. The invention proposes that the function circuit comprises at least one conductor track structure which is formed on the moulded part as a carrier of the conductor track structure. The function circuit can preferably be applied to the prefabricated moulded part, which is made of plastic, by means of an additive fabrication method (AM method).

A module bearing and a power transmission device including the module bearing. A module bearing includes a module outer wheel supported by and in contact with a side wall of a gear to guide rotational or linear motion of the gear, a bearing rotor rotatably disposed radially inward of the module outer wheel, and a part-assembly type module inner wheel disposed radially inward of the module outer wheel with the bearing rotor interposed therebetween and connected to the bearing rotor, in which a plurality of separate parts are manufactured and assembled into the part-assembly type module inner wheel to apply a preload to the bearing rotor.

A drawer slide including a base member, a roller support, ball bearings and roll pins. The base member a track base and first and second walls. The first and second walls and the track base define a first channel. The first wall has a first race and the second wall has a second race. The roller support is within the first channel. The roller support has first and second side walls and a center section disposed between the first and second side walls. The first and second side walls are disposed adjacent the first and second walls. The center section is disposed adjacent the track base. The first and second side walls have bearing apertures. The center section has roller openings. The ball bearings are disposed the first and second races. The roll pins are in the roller openings in rolling contact with the track base.

A system includes a carriage configured to move along a rail. The system also includes a clamping brake configured to selectively allow and prevent movement of the carriage along the rail. The clamping brake includes multiple brake pads configured to be moved inward to lock onto the rail and to be moved outward to release the rail. The clamping brake also includes multiple springs configured to apply spring forces that cause the brake pads to move inward and lock onto the rail. The clamping brake further includes a camshaft coupled to or including multiple eccentrics. The eccentrics are configured to overcome the spring forces and cause the brake pads to move outward and release the rail.

A drawer pull-out guide includes a first guide rail, a second guide rail displaceably supported relative to the first guide rail, and a running carriage which is displaceably supported between the first guide rail and the second guide rail. The running carriage includes at least three rolling bodies, each having a cylindrical form and being rotatable about a horizontally extending axis in a mounted position of the drawer pull-out guide. The at least three rolling bodies, in the mounted position of the drawer pull-out guide, are arranged in at least three running planes lying above one another.

A slider assembly (10) for a transportation system (100) for transporting an object (101) is provided. 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.
