Rigid locking gas springs
This type of gas spring also has a built-in valve in the piston, which can be operated in the same way as in the flexible locking gas spring. Here the piston is located in oil instead of gas, and the oil is separated from the gas by an auxiliary floating piston. Depending on the location of the gas, we differentiate rigid locking gas springs on pull and rigid locking gas springs on push (Figure 8. and Figure 9.). In both cases at one side of the piston there is only oil, so when the valve is closed the piston cannot move towards this space (rigid locking), and it can only move in the opposite direction if the external force exceeds the force generated by the pressure of the gas.

Identification:
MKB-3-1U2R-800-100-300
- MKB – rigid locking gas spring on pull (for the rest of the nomination, see standard gas spring)
- MKBN – rigid locking gas spring on push (for the rest of the nomination, see standard gas spring)
We produce rigid locking gas springs only with rod/tube dia. 10mm/28mm, damping 3 and 2R rod end fitting (M10x1x20 thread).

Release heads for lockable gas springs
You can find a selection of release heads available for our lockable gas springs in the end connectors section. The heads can be used both with flexible locking and rigid locking gas springs. Whether or not you need a release head, submit the dimensions of the gas spring (stroke and length until the thread, and 2R rod end fitting) without the release head, then indicate the type of release head separately. However, when establishing the extended length do not forget to calculate with the length of the release head.
Lever-type release heads do not contain the lever and the plastic button for the lever. These are separate parts. If you need the release lever and the plastic button as well, please indicate.
