A rail system (1) has a rail (20), a support device (10) for the rail (20), and a clamping device (40) for fixedly clamping the rail (20) in the support device (10). The clamping device (40) fixedly clamps the rail (20) in the support device (10) only in an operating situation. In the operating situation, a holding device (30) is arranged between the clamping device (40) and the rail (20) and releasably clamps the rail (20) in an installation situation in a predetermined position in the support device (10).

A slide structure includes a slide rail and a slide lid. The slide rail includes guide wall portions disposed in a first direction orthogonal to a rail longitudinal direction. A first abutting portion is provided in a guide wall face, and a second abutting portion is provided at a position separated in the rail longitudinal direction relative to the first abutting portion, and separated in a second direction orthogonal to the rail longitudinal direction and the first direction. The slide lid can slide along the rail longitudinal direction between the guide wall portions. A first projecting portion abutting against a top portion of the first abutting portion is provided on one side in a sliding direction, and a second projecting portion abutting against a top portion of the second abutting portion in a state wherein the first projecting portion abuts against the first abutting portion is provided.

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.

A cap of a linear guide device includes a receiving part configured to receive hitting of a hitting jig, a fitting part extending from the receiving part, having an outer diameter to be an interference with the counterbore part, and being press-fitted into the counterbore part, a foreign material receiving groove arranged at an outer circumference of the fitting part, and configured to receive a foreign material generated from the fitting part when the cap is hit into the counterbore part, and a gas discharge groove extending to reach an inside of the counterbore part from the foreign material receiving groove, with the fitting part being press-fitted into the counterbore part at the outer circumference of the fitting part, and configured to discharge a gas in the inside of the counterbore part to a foreign material receiving groove side.

In the case of a device for the detachable connection of a furniture pull-out movably guided in a furniture body via a guide unit with the guide unit having at least one adapter element detachably connectable with a running rail of the guide unit and having fastening elements for fixing the adapter element to a component of the furniture pull-out, the fastening elements comprise a catch for the detachable fastening of the adapter element to an assigned component of the furniture pull-out.

A rolling device, a package for rolling device and a rolling module are introduced. The rolling device includes a receiving seat defining a receiving recess, at least one secondary rolling member received in the receiving recess to contact with a surface of the receiving recess, a primary rolling member partially received in the receiving recess to contact with a surface of the at least one secondary rolling member, a coupling section connected to the receiving seat for coupling to an external object, and a stop section connected to the receiving seat and defining a stop opening, which has a size smaller than a maximum size of the primary rolling member.

An anti-rotation system having a replaceable keyway is disclosed, wherein the system comprises a housing having a bore extending along an axis of the housing, and a housing aperture extending from an outside surface of the housing to the bore and extending along the housing parallel to the axis of the housing; a member configured to slide within the bore along the axis of the housing; an insert defining a keyway removably mounted on the housing wherein the keyway extends at least partially into the housing aperture; and a key carried by the member and engaged with the keyway defined by the insert; wherein the key cooperates with the insert to resist rotation of the member about the axis of the housing.
