Page 1880 | 3.8 Adjusting, Moving with Guides, Spindles and Ball Rollers Rubber stop The rubber stops of type B dampen the impact of the slide in the respective end position. 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, dampened Telescopic slides GN 1424 have a dampened self-retrac- ting mechanism, which is also called “soft-close”. The dampened self-retracting mechanism is divided into two main functions and offers the best possible ease of use on closing the extension. The self-retracting mechanism takes over the automatic retraction of the slides on the last 40 mm of stroke in the back stop position, where the slides are held in place ac- cordingly. The retraction force is about 35 newtons per slide pair. Also, the dampening mechanism slows down to a considerably reduced speed the closing movement on the said stroke. An extremely smooth and gentle clo- sing movement is achieved. This retraction force has to be overcome accordingly on opening the extension. The dampened self-retracting mechanism is designed for loads weighing up to 75 kg based on 60,000 cycles (LGA standard). Proper use, including the reduction of the stro- ke speed to no more than 0.15 m/s on reaching the ret- raction mechanism, as well as compliance with the load values are required.
