Gas Spring End Fittings: Ball Joints, Clevises, Eyelets, and Brackets
End fittings are part of the gas spring load path. Select ball joints, clevises, eyelets, blade ends, brackets, and fasteners by articulation, alignment tolerance, mounting space, material, corrosion exposure, and peak load.
Choose fittings by movement and interface
| Fitting | Best suited to | Check before selection |
|---|---|---|
| Ball joint | Mechanisms where angle changes through the stroke. | Ball diameter, socket retention, articulation clearance, and bracket strength. |
| Clevis or fork | Defined pivot axis with a pin connection. | Inside width, pin diameter, hole position, and side clearance. |
| Eyelet or blade end | Compact fixed-pivot mounting. | Alignment, thread engagement, bracket thickness, and allowable rotation. |
RFQ details for fittings and brackets
- Photos of both ends and the mounting brackets.
- Thread size, ball-stud or pin diameter, clevis gap, and bracket thickness.
- Required rotation through the full stroke, force, length, material, corrosion exposure, and quantity.
- Any safety clip, release-handle, cable, or service-access requirement.
Frequently asked questions
Why do fitting failures occur?
Common causes are side load, poor alignment, vibration, corrosion, undersized fittings, weak brackets, and loose fasteners.
Can an old fitting be reused?
Only after checking its dimensions, load rating, material condition, articulation, bracket strength, and clearance in the replacement assembly.
