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 (VSTS-818-174-501-635N (S1S1)) rod mount is S1 (Шаровая опора (гнездо)) cylinder mount is S1 (Шаровая опора (гнездо)).

D1 is the rod diameter in millimeters. A larger diameter improves side-load capacity and buckling resistance. Match D1 when selecting an equivalent spring.

D2 is the outer body (cylinder) diameter. It defines overall size and affects force at a given pressure. Specify D2 together with D1 for accurate replacement.

C1 is the working rod stroke — how many millimeters the rod extends when the spring is fully compressed. Critical for lids, hatches and moving mechanisms.

C2 is the overall length in the fully extended state. Use it to verify the spring fits the assembly without interfering with nearby parts.

N1 is the 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.
