for smooth movement even with heavy weight SDD sliding door dampers

The SDD door damper, set against a modern backdrop, epitomises precision and reliable motion control.

The sliding door damper (SDD) is particularly suitable for heavy doors, windows, and drawers weighing 100 kg or more. It allows for a smooth and harmonious movement even with heavy weight. This makes it almost unrivaled in these applications. Due to its design and the ability to gently slow masses of over 100 kg moving in a straight line, the SDD provides considerable added value in various industries. The system is available in larger production batches and can be used for weights from 40 to 400 kg.

SDD Sliding Door Damper

Functional principle

The Sliding Door Damper (SDD) combines three features in one component: Cushioned docking, degressive braking, and gentle closing of heavy masses. This is made possible by the innovative combination of two gas springs and an oil brake. In this way, masses moving in a straight line are gently slowed down to their final position. The degressive braking effect ensures a smooth, harmonious movement – ​​even with heavy weights.
