The correct position of the gas spring
The lifespan of a gas spring strongly depends on the proper lubrication of its seals. To ensure this, the gas spring should always be installed with the rod pointing downward. This means the rod guide should be positioned lower than the cylinder.
Maintain an undamaged rod
The rod’s surface is critical for maintaining gas pressure. Avoid damage from sharp or abrasive objects or chemical substances. During installation, the upper and lower fittings must be properly aligned to prevent strain on the seal. If necessary, use articulated fittings to ensure proper alignment throughout the rod’s entire stroke.
Reduce vibrations and friction
Vibrations from the machine to which the gas spring is attached can be transmitted to the seals via overly rigid connections. Leave a small clearance between the mounting screws and attachments or use at least one articulated fitting. Smooth pins should be used instead of threaded bolts, as the thread crests in contact with the attachment hole can cause friction, which may hinder the gas spring’s performance.
Load and pulling force of the gas spring
Ensure that the pulling force does not exceed the gas spring’s thrust force. This helps maintain the normal sliding speed of the rod and prevents excessive wear.
Environmental factors
Gas springs typically operate within a temperature range of -30 °C to +80 °C. However, damp and cold environments can cause frost to form on the seals, potentially affecting the gas spring’s lifespan.
Safe use of the gas spring
Gas springs are designed to lighten or balance heavy loads. If used for other purposes, such as shock absorption or deceleration, this must be carefully evaluated by designers and manufacturers to ensure the spring’s durability and safety.
