GN 1450 Telescopic Slides Stainless Steel, with Full Extension, Load Capacity up to 108 lbf

For the listed loading forces F_S to be absorbed reliably in the surrounding structure, all available through holes of the outer and inner slide having a Ø of 4.5 mm must be used. Alternatively, the outer slide has holes with a Ø of 6.3 mm for metric screws. The slotted holes, Ø 4.5 x 4.8 mm, 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:

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.

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.

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.
