Changzhou LongXiang Gas Spring Co.,Ltd

Gas springs usually work for thousands of cycles with little routine attention, but they do not last forever. A unit that loses force, binds, leaks or has damaged mounting hardware can create an unsafe lid or panel. LONGXIANG GAS SPRING recommends regular visual and functional checks so replacement can be planned before performance becomes unreliable.

Common Signs of Wear

The clearest warning is reduced support force. A lid that once stayed open may begin to drift downward or require extra hand effort. Uneven extension, jerky movement or a change in damping can indicate internal wear, contamination or pressure loss.

A light oil film may sometimes appear near the seal, but visible dripping or repeated oil accumulation deserves attention. Inspect the piston rod for scratches, corrosion, bending or impact marks. Because the rod passes through the seal during every cycle, surface damage can quickly increase leakage.

Check the Complete Installation

Not every problem comes from the gas spring itself. Loose brackets, worn ball sockets, bent hinges and misaligned mounting points can produce noise or poor motion. Move the application slowly through its full travel and confirm that both end fittings rotate freely without side load.

LONGXIANG GAS SPRING also recommends checking mechanical stops. The gas spring should not be used as the fully open or fully closed stop. Repeated impact at the end of stroke can damage the cylinder, rod, brackets and surrounding structure.

Simple Inspection Checklist

• Confirm that the lid or guard remains supported at the intended position.

• Check for oil leakage, corrosion or physical damage.

• Inspect brackets, fasteners, hinges and end fittings.

• Verify smooth movement without binding or sudden acceleration.

• Make sure the piston rod is clean and free from scratches.

• Check that cables or release controls operate correctly on lockable models.

• Compare left and right units when two gas springs are installed.

When Replacement Is the Better Choice

Replace a gas spring when it no longer supports the specified load, the rod is bent or badly corroded, oil leakage continues, or locking performance becomes inconsistent. Sealed gas springs should not be drilled, heated, opened or refilled without an approved service procedure.

When replacing a unit, record the extended length, compressed length, stroke, force rating, rod and tube diameters, end-fitting type and mounting orientation. Review the LONGXIANG GAS SPRING product range for available configurations.

Improve Service Life

Keep the piston rod clean with a soft cloth and protect it from paint, abrasive dust, welding spatter and aggressive chemicals. Avoid gripping the rod with tools. Use aligned brackets and independent mechanical stops, and select stainless steel construction for corrosive or washdown environments when appropriate.

Frequently Asked Questions

Should paired gas springs be replaced together?

Usually yes. Replacing both helps maintain balanced force and reduces twisting on wide lids.

Can a weak gas spring be repaired?

Most standard units are sealed and are replaced rather than repaired. Adjustable or serviceable designs require the manufacturer’s approved procedure.

What information should I send for a replacement?

Send dimensions, force, end fittings, application weight, mounting points and photos through the LONGXIANG GAS SPRING contact page.

Conclusion

Regular inspection protects users and equipment. LONGXIANG GAS SPRING can help confirm replacement specifications and recommend a suitable configuration for the actual load, geometry and working environment.
