Parameter guide

What are mounts? Rod and cylinder end fittings

Gas spring mounts are end fittings that connect the spring to the structure. Mount type affects installation, rotation angle, allowable loads and service life.

Common options:

  • Ball socket — quick to install and allows free rotation.
  • Threaded stud — versatile with brackets or adapters.
  • Clevis — reliable pin or bolt mounting for higher loads.
  • Rod end bearing — compensates misalignment and reduces rod stress.
  • Eyelets and special ends — for non-standard applications.

Consider mechanism design, motion direction and operating conditions. The right mount ensures reliable long-term performance.

On this gas spring (7811MS) rod mount is R13 (Резьба штока) cylinder mount is E102 (type not specified).

What is rod Ø? Rod diameter

Rod diameter in millimeters. A larger diameter improves side-load capacity and buckling resistance. Match rod Ø when selecting an equivalent spring.

Before ordering gas spring Stabilus 7811MS or VST VSTLE-1023-80-340-500N (R13E102) with delivery to Saint Petersburg, confirm rod Ø 10 mm fits your application.

What is cylinder Ø? Cylinder diameter

Outer body (cylinder) diameter. It defines overall size and affects force at a given pressure. Specify cylinder Ø together with rod Ø for accurate replacement.

Cylinder Ø 28 mm on Stabilus 7811MS defines body size. Compare with Stabilus 0004MN — same cylinder Ø for parameter-based selection.

What is rod stroke? Working stroke

Working rod stroke — how many millimeters the rod extends when the spring is fully extended. Critical for lids, hatches and moving mechanisms.

Rod stroke 85 mm on gas spring Stabilus 7811MS sets how far a lid or hatch opens. In Блокируемые с эластичной блокировкой with the same stroke: Stabilus 001073.

What is length? Extended length

Overall length in the fully extended state. Use it to verify the spring fits the assembly without interfering with nearby parts.

Overall length 278 mm on Stabilus 7811MS is a key installation dimension. Gas spring VST VSTS-818-70-278-470N-N (S1S1) has the same length — compare mounts, rod Ø and force before replacement.

What is force? Force in newtons

Gas spring force in newtons. It determines whether the spring can hold or lift the load. Small tolerance is acceptable; a large difference changes mechanism behavior.

Force 300 N on gas spring Stabilus 7811MS must match your load. Stabilus 000726 has the same force — useful when choosing a replacement. You can then order a gas spring with delivery to Saint Petersburg.
