Telescopic Slides GN 1408

Product description

Information

GN 1408 telescopic slides are installed in pairs. The stroke reaches ≈ 100 % of the nominal length l₁ (full extension).

The telescopic slides are delivered in pairs. They can be installed on either the left or right side due to the design. All mounting holes are easy to reach through auxiliary holes. Only the mounting holes are shown, but other production-related holes may be present.

Mounting Screws

For the listed loading forces F_S to be absorbed reliably in the surrounding structure, all available through holes of the outer slide having a Ø of 4.2 mm and of the inner slide having a Ø of 4.4 mm must be used. The slotted holes, Ø 4.2 x 4.4 mm of the outer slide and Ø 4.4 x 4.6 mm of the inner slide, are also used for mounting and facilitate adjustment. Failure to use mounting screws reduces the specified load capacity accordingly. The following screws can be used for mounting:

Socket button head screw ISO 7380
Phillips pan head screw ISO 7045
Phillips pan head self-tapping screw ISO 7049

Rubber Stop, Locking Device in Retraced Position

The rubber stops dampen the impact of the slide in the two end positions. This feature minimizes noise development and increases the service life. Attached to the slides in a partially concealed, partially visible manner, the stops meet each of the requirements in regards to shape, material, and hardness.
In the retracted end position, the rubber stop additionally takes on a locking function, which is noticeable through a slight resistance on opening and closing.
If larger static or dynamic loads occur in the direction of extension, they should be absorbed by additional stop elements.

Detach Function

The detach function allows the extension to be completely separated from one another in the area of the middle and inner slide. This feature not only facilitates mounting, it also allows the extension to be quickly removed, for example when frequent maintenance work is performed on the components located behind.

The telescopic slide can be quickly and easily detached in the extended position through activation of the release lever, allowing the inner slide to be removed from the front.

For re-attaching the slides, the ball cages need to be moved to the extended end position. Then the inner slide is inserted to the retracted end position where it locks into place automatically.

The protected arrangement of the release mechanism prevents accidental detachment of the slide.

Load Capacitiy


The maximum load capacity of telescopic slides depends on the slide cross-section and the nominal length l₁ as well as the resulting stroke l₂. Furthermore, the extension width, the slide materials used and the components of the equipment options, such as the dampened self-retracting mechanism, have a corresponding influence. The information on the maximum load capacity of the telescopic slides was determined in endurance tests under the following conditions:
Slide arrangement in pairs, side mount Observance of all mounting information Warp-resistant test setup Equal distribution of the maximum load F_S over the entire extension area Standard slide spacing of 450 mm 10,000 or 100,000 test cycles (one extension and one retraction = one cycle) Gradual increase of the load
Wear, performance, and maximum bending were assessed after each test section.
