This feature minimizes noi- se 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 sha- pe, material, and hardness. If larger static or dynamic loads occur in the direction of extension, they should be absorbed by external stop ele- ments. Self-retracting mechanism Telescopic slides GN 1432 have an integrated self-retrac- ting mechanism, which improves considerably the ease of use when closing the extensions. The slides are retracted and held in the back end position automatically by means of a retraction mechanism on the last 22 mm of stroke with a force of approximately 30 new- tons for each slide pair. This force has to be overcome accordingly on opening the extension. The self-retracting mechanism is also designed in such a way that it uncouples and will not be damaged when the extension is opened or closed in a jerky manner or too quickly. On the following stroke, the self-retracting mechanism clicks back into place automatically, ensuring that the function remains intact. GN 1432 Telescopic Slides continued
