In this model, the piston’s entire stroke is immersed in oil, which creates a stable locking effect. Vertical installation of the gas spring is required, but this design eliminates the need for additional components such as a separating piston.
If the gas spring must lock in the pulling direction, the piston rod should be installed facing downward. For locking in the pushing direction, the piston rod must be installed facing upward.

✔ Cost-efficient model with strong fixed locking performance due to oil damping
✔ Stable locking at any position, providing excellent balance during movement
✔ Compact design with minimal space requirements
✔ Easy installation with a variety of end-fitting options

🔹 Height adjustment of hospital beds and operating tables
🔹 Adjustment of supports and chair backrests

✅ Locking Method:
A standard lockable gas spring provides elastic locking and can be opened or closed with slight push or pull, whereas a fixed-lock gas spring becomes fully locked and cannot move once engaged.

✅ Installation:
A standard model can be installed in any orientation, while a fixed-lock gas spring typically requires vertical installation and is designed for specific positioning requirements.

✅ Applications:
Standard models are suitable for general adjustments such as chairs, while fixed-lock gas springs are used in medical equipment such as hospital beds and operating tables.

✅ Performance:
A standard gas spring allows easy adjustment with an elastic response, whereas a fixed-lock gas spring remains completely rigid once locked.

This gas spring locks securely in any position. However, when quick adjustment is needed, the tabletop can be lifted easily and safely without activating the release mechanism—simply by applying upward pressure from below.
To lower the tabletop, the release lever must be pressed.
For optimal performance, this gas spring is typically installed in a vertical orientation.

✔ Allows fast, safe upward adjustment of locked tabletops without releasing the mechanism
✔ User-friendly operation with enhanced safety
