Dynamic Groove Gas Spring

The Bansbach Dynamic Groove Gas Spring utilises a specialised groove machined inside the cylinder to deliver high‑precision, position‑independent damping — a significant advancement over conventional nozzle‑based gas spring damping systems. Rather than relying on fluid passing through a small orifice, the damping effect is controlled directly through the engineered groove, allowing consistent performance in all installation orientations — whether horizontal or with the piston rod pointing upwards.

This technology is ideal for applications requiring smooth motion control under varied mounting positions and consistent, tailored damping characteristics. The groove profile can be precisely adapted to your exact requirements, enabling a gentle, controlled transition into full damping that also minimises wear on surrounding structures.

The dynamic groove option is available for gas springs with cylinder diameters of 15 mm, 19 mm and 22 mm, and is often found in precision equipment across furniture, medical devices, special vehicles and mechanical engineering sectors where controlled motion in varying orientations is essential.

Key Features

• Groove‑controlled damping for smooth, tunable motion rather than conventional nozzle fluid restriction.
• Position‑independent performance — consistent damping in horizontal or vertical orientations.
• Customisable damping characteristics over the full stroke to meet specific application needs.
• Reduced structural stress and wear through controlled transition into damping.
• Available in cylinder sizes: 15 mm, 19 mm and 22 mm.
• Ideal for precision motion applications in furniture, mechanical engineering, special vehicles and medical equipment.
