LX Gas Spring Resource
Learn practical gas spring maintenance, inspection, cleaning, installation orientation, corrosion prevention, and replacement warning signs.
Most gas springs are sealed units and should not be opened, drilled, welded, heated, or modified after production. The internal nitrogen pressure can be dangerous if the cylinder or rod is damaged. Maintenance is therefore focused on correct installation, clean operation, regular inspection, and timely replacement rather than repair.
Protect the piston rod from scratches, paint, adhesive, dust, and impact. The rod passes through the seal system, so surface damage can shorten service life. If the rod is bent or the tube is dented, the gas spring should be replaced rather than forced back into use.
Follow the recommended mounting direction for the application. A common approach is rod down orientation in the resting position so internal oil helps lubricate the seal. Avoid transverse force and misalignment. The end fittings should pivot freely through the full range of motion without binding.
Keep the surrounding area clean enough that abrasive particles do not collect on the rod. In outdoor, marine, food equipment, medical, or washdown conditions, consider SS316 stainless steel gas springs /products/stainless steel gas springs or corrosion resistant designs during the selection stage rather than trying to solve corrosion later.
Replace a gas spring if the lid no longer stays open, the rod extends unevenly, oil leaks are visible, the tube is damaged, fittings are loose, or the motion becomes unsafe. If the application uses two gas springs, replacing both together can help maintain balanced motion.
For OEM equipment, create a service instruction that records extended length, compressed length, stroke, force, end fitting style, and replacement part reference. This makes future maintenance easier for distributors and end users.
Record printed markings, measure gas spring dimensions /resources/gas spring dimensions , note the application, photograph both end fittings, and describe the working environment. If the original part failed early, send photos of the bracket geometry and installation orientation so the cause can be reviewed.
For new designs, review the mounting guide /resources/gas spring mounting guide , check force using the gas spring force calculator /resources/gas spring force calculator , and contact LX Gas Spring /contact with drawings before production.
Most standard gas springs are sealed and should be replaced rather than opened or recharged.
Common causes include scratched rods, side loading, poor alignment, corrosion, excessive force, impact damage, and unsuitable mounting geometry.
Often yes, especially when balanced motion is important or both parts have similar service time.
