GN 1410 Telescopic Slides with Full Extension, Load Capacity up to 510 N

For the said loading forces F_S 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:

The rubber stops of type F dampen the impact of the slide in the respective end position. This feature minimizes noise development and increases the lifespan. Attached to the slides in a partially concealed, partially visible manner, the stops meet each of the requirements in regard to shape, material, and hardness.
In the back stop position, the rubber stop takes on additionally 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 external stop elements.

Type F has additionally 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. 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 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.

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 dampened 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 F_S throughout the extension finish
• Standard slide spacing of 450 mm
• 10,000, 50,000 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.
