Product description

Information

Telescopic slides GN 1440 are installed vertically and in pairs. The stroke reaches ≈100 % of the nominal length l1 (full extension). Patented plastic ball cages ensure extremely smooth running of the slide.

Telescopic slides of various types, for example, with and without latch, can be combined freely, which is why GN 1440 is delivered as a single unit and not in pairs. Thanks to the symmetrical design, all types can be installed on either the right or left side on the extension.

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 6.6 must be used. Alternatively, holes with a diameter (Ø) of 5.2 are available. The elongated holes, Ø 6.6 x 3.4, facilitate adjustment during mounting when needed. Failure to use fastening screws reduces the load capacity. The following screws can be used for mounting:

Hexagon socket button
head screw ISO 7380
Hexagon socket low cylindrical
head screw DIN 7984 / DIN 6912

Rubber stop

Type B with rubber stop

Drawing rubber stop GN 1440

The rubber stops of type B 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.
If larger static or dynamic loads occur in the direction of extension, they should be absorbed by external stop elements.

Type M with rubber stop, latch in back

Drawing Rubber stop2 GN 1440

Type M is used in applications in which the slide needs to be locked in the back end position. This feature prevents the slide from extending on its own, for example, due to a tilted position. If larger loads occur in the direction of extension in the latched position, they should be absorbed by external latch elements.
The latch mechanism locks into place in a spring-loaded opening of the outer slide in the closed state. Pressing the release lever releases the inner and middle slide for extension. Back in the back stop position, the mechanism locks into place automatically in the opening of the outer slide by moving over a ramp.

Type K with rubber stop, latch in front

Drawing rubber stop3 GN 1440

Type K is used when the extension needs to stay in the front stop position for a certain amount of time. This feature allows maintenance work to be performed when the extension is expanded, for example. If larger loads occur in the latched position, they should be absorbed by external latch elements.
For the function to be activated, the slide has to be fully extended to the front, where it will automatically click into place through a pretensioned locking lever. Pressing the lever releases the slide, allowing slide to retract again.

Type Q with rubber stop, latch in back-front

Drawing rubber stop4 GN 1440

Type Q unites the properties of types M and K. The inner and middle slide lock into place in the respective end position.
Unlike the release of type K, type Q is activated through an internal rod by a convenient “remote control.” The green activation lever is pressed out, the locking lever activated, and the slide released for retraction.

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 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 FS 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

Drawing Load capacity telescopic slides

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