Mounting Orientation & Alternative Solutions
Gas Spring & Gas Strut Mounting Instructions
▪ Standard gas springs contain a small amount of oil to lubricate the piston rod seal and provide end-of-stroke damping.
▪ Mounting rod-up prevents oil from reaching the seal, causing accelerated wear and reduced lifespan.
▪ Recommended: rod down at least 30° off horizontal. If rod-down mounting is not possible, specify an oil or grease chamber.
Why Gas Springs Should Be Used Rod-Down
▪ Keeps piston rod and seal lubricated for optimal sealing and prevents drying out.
▪ Ensures high damping effect at the end of the stroke.
Gas Springs Rod Down
▪ Basic design suggestion: keep mounting angle less than 60° from vertical.
▪ Oil contact improves sealing and damping characteristics.
Alternative Solutions
When rod-up or near-horizontal mounting is necessary:
▪ Use gas springs with an oil chamber or fully damped gas springs.
▪ These maintain performance comparable to standard rod-down springs.

Temperature Effects
How temperature affects gas spring force: the force produced by a gas spring varies linearly for each degree change from ambient.
Gas Spring & Strut Operating Temperature Range: The following chart gives the operating and survival temperature ranges for gas springs manufactured with standard, low temperature and high temperature seals.
| Type Gas Spring | Operating Temp. Range | Survival Temp. Range |
|---|---|---|
| Standard and Stainless Steel | (-25°C to +70°C) | (-35°C to +70°C) |
| Low Temp. | (-40°C to +95°C) | (-50°C to +95°C) |
| High Temp. | (-5°C to +175°C) | (-15°C to +175°C) |
