Gas spring OEM Sirona 5856781

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 (5856781) rod mount is R31 (type not specified) cylinder mount is C0 (type not specified).

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 OEM Sirona 5856781 or VST VSTLE-1023-80-340-500N (R13E102) with delivery to Saint Petersburg, confirm rod Ø 10 mm fits your application.

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 OEM Sirona 5856781 defines body size. Compare with Stabilus 000657 — same cylinder Ø for parameter-based selection.

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

Rod stroke 45 mm on gas spring OEM Sirona 5856781 sets how far a lid or hatch opens. In Стандартные with the same stroke: Stabilus 002043.

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

Overall length 222 mm on OEM Sirona 5856781 is a key installation dimension. Gas spring VST VSTS-1028-45-222-460N-6 (R31C0) has the same length — compare mounts, rod Ø and force before replacement.

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 1120 N on gas spring OEM Sirona 5856781 must match your load. VST VSTS-1023-80-265-1120N (S8S8B7) has the same force — useful when choosing a replacement. You can then order a gas spring with delivery to Saint Petersburg.
