Adjusting and locking – safe and simple Locking gas springs

Need to provide easy operation of heavy panels and covers? Or perhaps ergonomic adjustment of chairs and tables to suit different users’ statures? Stabilus locking gas springs ensure optimal counterbalancing at all times in applications like these. Smooth travel during opening, closing, and positioning are right there in the operator’s hands. 

Our BLOC-O-LIFT series locking gas springs can also easily be locked in any position. This functionality can be designed as rigid or elastic and to be effective in the push or pull direction.

STAB-O-MAT and STAB-O-BLOC gas springs are lockable gas springs specially designed for infinitely variable and comfortable seat height adjustment in office swivel chairs, task chairs, armchairs, stools, etc.

For any set of installation conditions – and every single need

Our standard product line contains a broad selection of locking gas springs. That means it’s sure to have the right product for any set of installation conditions.

However, if you need a custom product, our years of experience as a pioneer in gas spring production make us the perfect partner in development. We work together with you to find the right solution for your individual specifications.

In practice: no feats of strength – because the power is already there

BLOC-O-LIFT locking gas springs have a special piston valve system that separates the two piston chambers in the spring. This enables locking in any position without excessive physical effort. The gas spring locks when the valve tappet is released from the outside and the connection between the two pressure chambers is interrupted. 

This is how locking gas springs from Stabilus hold even heavy loads in the desired position reliably. When the valve is open, the linear spring characteristics of the BLOC-O-LIFT ensure a uniform increase in force through the entire range of movement.
