Industrial Gas Springs – Push Type
GS-28-550

Individual stroke length and extension forces

Valve Technology
Extension force max. 303 lbs
Stroke 21.65 inch

Universal and tailor made: ACE industrial gas springs offer perfect support of muscle power with forces from 2 to 2,923 lbs. (10 to 13,000 N) with body diameter of 0.31"" to 2.76"" (8 to 70 mm). These durable and sealed systems are ready for installation, maintenance-free and filled with pressurized nitrogen gas.

They are filled according to individual customer pressure requirements and may be adjusted later by use of a built-in valve. ACE provides free calculation support and designs the gas springs with mounting points specifically for the particular application. A variety of accessories makes assembly even easier and allows universal application of the gas springs.

Technical Data

Extension force max. 303 lbs

Piston rod diameter Ø 0.55 in

Progression Approx. 63 % to 76 %

Lifetime Approx. 32,808 ft

Operating temperature range -4 °F to 176 °F

Material Outer body: Steel coated with UV paint; Piston rod: Steel with wear-resistant coating; End fittings: Zinc plated steel

Operating fluid Nitrogen gas and oil

Mounting In any position. Hint: We recommend mounting with piston rod downwards to take advantage of the built-in end position damping.

End position damping length approx. 1.18"""" to 2.76"""" (depending on the stroke)

Positive stop External positive stop at the end of stroke provided by the customer.

Note

Integrated grease chamber reduces friction and wear and optimizes lubrication.

End fittings

They are interchangeable and if necessary must be positively secured by the customer to prevent unscrewing.

Safety information

Gas pressure springs should not be installed under pre-tension.

On request

Special oils and other special options. Alternative accessories. Different end position damping and extension speed.
