GN 1404 Telescopic Slides with Partial Extension, Load Capacity up to 780 N

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

Designation - standard
Countersunk screw, Phillips DIN 965
Countersunk screw, Phillips DIN 7997

Outer slide
M 5
Size 5

Inner slide
M 5
Size 4,5

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.
