Page 1866 | 3.8 Adjusting, Moving with Guides, Spindles and Ball Rollers Self-retracting mechanism Telescopic slides GN 1412 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 30 mm of stroke with a force of approximately 25 new- tons for each slide pair. In this slide variant the available retraction force can be regarded as a locking device, which is noticeable through a slight restriction on opening the extension. Detach function Type F has additionally a detach function through which the extension slides can 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 fre- quent maintenance work is performed on the components located behind. The telescopic slide can be quickly and easily detached in the extracted position through activation of the release lever, allowing the inner slide to be removed from the front. For reattaching the slides, the ball cages need to be moved to the front end position. Then the inner slide is inserted to the back end stop where it locks into place automatically. The protected arrangement of the release mechanism pre- vents accidental detachment of the slide. GN 1412 Telescopic Slides continued
