GN 1414 Telescopic Slides Steel, with Full Extension and Dampened Self-Retracting Mechanism, Load Capacity up to 80 lbf


Product description


GN 1414 telescopic slides are installed vertically and in pairs. The stroke reaches ≈ 100 % of the nominal length l1 (full extension).

The rubber stops of type F dampen the impact of the slide in the end positions. This feature minimizes noise development and increases the lifespan. If larger static or dynamic loads occur in the direction of extension, they should be absorbed by external stop elements.

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

Fastening screws

For the said loading forces FS to be absorbed reliably in the surrounding structure, all available through-holes of the outer and inner slide having a diameter (Ø) of 4.5 must be used. Alternatively, the outer slide has holes with a diameter (Ø) of 6.3 for Euro screws. The elongated holes, Ø 4.5 x 4.8, are used likewise for fastening and facilitate adjustment during mounting when needed. Failure to use fastening screws reduces the specified load capacity accordingly. The following screws can be used for mounting:

Self-retracting mechanism, dampened


GN 1414 telescopic slides have a dampened self-retracting mechanism, which is also called “soft-close”. The dampened self-retracting mechanism is divided into two main functions and offers the best possible ease of use on closing the extension.
The self-retracting mechanism takes over the automatic retraction of the slides on the last 1.85 pulgadas (47 mm) of stroke in the back stop position, where the slides are held in place accordingly. The retraction force is about 8.99 lbf (40 newtons) per slide pair. Additionally, the closing movement is slowed down considerably by the dampening mechanism. An extremely smooth and gentle closing movement is achieved. This retraction force has to be overcome accordingly on opening the extension.
The dampened self-retracting mechanism is designed for loads weighing up to 79 lbs (36 kg) based on 60,000 cycles (LGA standard). Proper use, including the reduction of the stroke speed to no more than 0.49 ft/s (0.15 m/s) on reaching the retraction mechanism, as well as compliance with the load values are required.

In this slide variant the available retraction force can be regarded as a locking device, which is noticeable through a slight restriction on opening the extension.


Detach function


Type F has a detach function through which the extension slides can be completely separated from one another in the area of the middle and inner slide. This feature not only facilitates mounting, but 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 extracted position through activation of the release lever, allowing the inner slide to be removed from the front.

For reattaching the slides, the ball cages need to be moved to the front end position. Then the inner slide is inserted to the back end stop where it locks into place automatically.

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


Information on load capacity

The maximum load capacity of telescopic slides depends on the slide profile, the nominal length l1, and the resulting stroke l2. Furthermore, the extension width, the slide materials used, and the parts of the component options, such as the damping self-retracting mechanism, have a considerable influence.
The information on the maximum load capacity of the telescopic slides was determined in fatigue tests under the following conditions:

- Slide arrangement vertical in pairs
- Observance of all mounting information
- Warp-resistant test set-up
- Equal distribution of the load FS throughout the extension finish
- Standard slide spacing of 17.72 inches (450 mm)
- 10,000 or 100,000 test cycles (one extraction and retraction = one cycle)
- Gradual increasing of load


Wear, performance, and maximum bending were assessed after every test segment.
