A device for guiding a movable furniture part on a furniture carcass. The device includes a carcass rail arranged on the furniture carcass and a movable rail movable in the opening and closing direction relative to the carcass rail. The carcass rail and the movable rail each have a flat running web and load-transmitting rolling elements are each arranged between a running web of the carcass rail and a running web of the movable rail. During relative movement between the rails, the rolling elements move along the running webs. The running webs are uninterrupted, and the rolling elements between the rails are configured such that, in the mounted state, the running web of the movable rail is always oriented obliquely relative to the running web of the carcass rail.

An actuator is equipped with a body and a slider. Body side rail grooves are formed in side wall portions that constitute the body. On the other hand, slider side rail grooves are formed in the slider. Body side guide rails and slider side guide rails are provided in the body side rail grooves and the slider side rail grooves, respectively. Circular arc grooves serving as ball grooves are formed by body side ball receiving portions of the body side guide rails, and slider side ball receiving portions of the slider side guide rails.

The present invention discloses a rolling-bulging forming hydraulic machine for tubular products, which includes a frame. The frame is provided with an upper rolling mechanism, a lower rolling mechanism, a fixed liquid bulging hydraulic cylinder and a movable liquid bulging hydraulic cylinder. The upper rolling mechanism and the lower rolling mechanism are arranged oppositely, and the upper rolling mechanism and the lower rolling mechanism are used to roll surfaces of a to-be-machined tubular product. The fixed liquid bulging hydraulic cylinder and the movable liquid bulging hydraulic cylinder are arranged oppositely, and the fixed liquid bulging hydraulic cylinder and the movable liquid bulging hydraulic cylinder are used to perform hydraulic bulging on the to-be-machined tubular product.

A slide rail comprises a longitudinal body and a pair of longitudinal supporting structures extended from two sides of the longitudinal body. Each of the supporting structures has a U-shaped cross section and includes a first supporting arm and a second supporting arm bent relative to the first supporting arm. A ball raceway is formed on one of the first supporting arm and the second supporting arm. The slide rail is applicable to a slide rail assembly for increasing strength.

A securable rail guide contains a guide rail, a runner rail arranged in the guide rail and able to travel along the guide rail, and a securing unit which is embodied to fix the runner rail in position in the guide rail in a releasable manner. A locking unit is arranged on the guide rail and is embodied to secure the runner rail in a locked position, and an unlocking unit is arranged on the runner rail. The locking unit and the unlocking unit are parts of the securing unit. The unlocking unit is operatively connected to the locking unit such that an actuation of the unlocking unit releases the runner rail to allow a free movement along the guide rail. This configuration provides a separation of the locking and unlocking mechanisms, as a result of which an independent configuration of the stability of the overall locking mechanism is possible.

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 machine tool includes: a movably configured saddle; and a bed having a sliding surface supplied with a lubricant and allowing the saddle to slide thereon, and receiving the weight of the saddle. The sliding surface has a recess continuously extending in a direction in which the saddle moves. By this configuration, a machine tool which easily holds a lubricant on a sliding surface and a method for producing a structure for the machine tool having the sliding surface are provided.

A seat track assembly including a first rail configured to move along a second rail. The assembly may include a roller cage disposed at least partially between the first rail and the second rail. In embodiments, the assembly includes a stopper that projects from an inner surface of the second rail and is configured to restrict movement of the roller cage while the movement of the first rail relative to the second rail is independent of the stopper.

The invention relates to a linear guide (1) having at least one inner and at least one outer profile-member (2, 3), the outer profile-member (3) at least partially surrounding the inner profile-member (2) and the profile-members (2, 3) being guided one inside the other by means of at least two linear guiding means which are preferably arranged diametrically opposite each other, wherein at least a portion of a first linear guiding means is arranged in a floating manner.

A three-section synchronous concealed slide rail includes a mobile rail, a middle rail, a fixed rail and a damping mechanism. An upper rack and an upper roller cage with an roller are installed between the mobile rail and the middle rail, a split-type lower roller cage with a roller is installed between the middle rail and the fixed rail, a surface of which is provided with a rack. A gear assembly is meshed between the upper rack and the lower roller cage and used for controlling synchronous or staggered operation of the mobile rail and middle rail according to the intensity of acting force, and the damping mechanism is installed on the fixed rail.
