Industrial Gas Springs and Gas Struts

Gas compression springs provide controlled assistance for lifting, lowering and balancing moving loads without an external pneumatic or hydraulic supply.

A typical spring contains a pressure cylinder, piston, piston rod, seals, nitrogen and a small amount of oil for lubrication and damping.

Extension speed, damping length and force progression can be specified for the application within the limits of the selected spring size.

Where end-of-stroke damping is required, rod-down mounting is generally recommended. Confirm the orientation and mounting geometry for the application.

Gemini's General Spring Specification defines 5,000 cycles in worst conditions and 70,000 cycles at 20°C +/- 2°C and 60% humidity, depending on application, stroke length and force. These are test conditions, not a guaranteed service life.

Available sizes range from 4/12 mm to 20/40 mm, with strokes from 10 mm (0.39 in) to 1,000 mm (39.37 in) and forces from 7 N (1.58 lbf) to 5,000 N (1,125 lbf). Standard operating temperature is -30°C to +80°C (-22°F to +176°F); special-temperature options may be available.
