GAS STRUTS

The gas strut (or lift-o-mat damper) supports and guides the opening of lids and doors on machines such as vacuum chamber packers, heat sealers and kneaders, stopping them from staying stuck open or slamming shut.

Organized by force in Newtons: 0-99N for light lids, 100-199N for light-to-medium weight, 1000-1500N for large, heavy lids.

How to choose the right replacement: besides the force in Newtons (printed on the original strut), the stroke length and the mounting hole diameter at the brackets also matter.

For other spare parts see Spare Parts.

Frequently asked questions

How do I know how many Newtons I need?
The force is usually printed on the body of the original strut; alternatively it can be calculated from the weight and geometry of the lid to be supported.

Can I fit a strut with a different force than the original?
No: an undersized strut can't hold the weight, while an oversized one makes the lid snap upward. Always match the original force rating.

  • <p>The gas strut (also called a lift-o-mat damper) supports and guides the opening of lids, covers and doors on machines such as heat sealers, vacuum chambers and small vacuum packers, preventing them from staying stuck open or slamming shut.</p> <p><strong>Force in Newtons</strong>: the <strong>100-199N</strong> range covers light-to-medium weight lids &mdash; a middle ground between the lighter models (<a href="/en/gas-struts-0-99-newton.html">0-99N</a>) and those for heavier loads (<a href="/en/gas-struts-1000-1500-newton.html">1000-1500N</a>). Too little force and the lid falls back down; too much and it snaps upward: it always needs to be matched to the weight and geometry of the original door.</p> <p><strong>How to choose the right spare part</strong>: besides the force in Newtons, the <strong>stroke length</strong> (extended and retracted length) and the <strong>mounting hole diameter</strong> on the brackets also matter.
