GN 1426 Telescopic Slides Steel, with Double-Sided Full Extension, Load Capacity up to 310 lbf

For the listed loading forces FS to be absorbed reliably in the surrounding structure, all available countersunk holes of the outer and inner slide must be used. Failure to use mounting screws reduces the specified load capacity accordingly. The following screws can be used for mounting:

Designation - Standard
Phillips countersunk flat head screw DIN 965
Phillips countersunk flat head self-tapping screw DIN 7997

Outer Slide
M 5
Size 5

Inner Slide
M 4
Size 4 / 4.5

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.
