Gas Springs

Now you can purchase your gas springs from the same reliable source that has supplied your stock mechanical springs -- SPEC®. Our stock gas springs use the latest sealing technology for a longer service life.

Our stock selection consists of various pressure, stroke and end fitting lengths. This flexibility allows the use of a stock gas spring in almost any application. Typical functions include counter-balancing, lifting, lowering, extending and retracting.

Construction Features

• Durable rod construction with anti-corrosion surface,
• Exclusive seal construction allows for mounting in various positions,
• Self-contained lubrication for long life and smooth operation,
• Selection of various end fittings for universal applications.

Application Considerations

The preferred mounting operation is rod down. Location of attachment points will alter the load carrying characteristics of the gas spring. For counter-balancing applications, the center of gravity and its respective load or force is essential to proper gas spring selection. In all cases, geometry plays a critical role in the application and life of the gas spring.

End Configurations

Our G0819 and G0122 series have threaded ends, which allow for the selection of blade, clevis (fork) or ball ends. To determine the approximate overall length of the spring with attached ends, add the E dimension to the body length (BL).

Mounting Options

• Blade Ends are generally mounted over a shoulder bolt or a similar fixed shaft.
• Clevis Ends are designed to slide over a bracket.

Align Blade and Clevis end mountings parallel to each other. Proper alignment throughout the operating range is essential to obtain maximum life cycle.

• Ball Ends are specifically designed to allow for a slight misalignment (up to 12 degrees) over the operating range of the spring.

The preferred mounting orientation is rod down.

Part Specification

For our G0819 and G1022 series, the end suffix as shown on the following tables must be added to the part number.

Example: to order cylinder G0819-100-100 with a -1 blade end on the rod end, and a -3 clevis on the cylinder end, specify G0819-100-100-1-3.

Spring Force

The force listed is for the fully extended spring. The force will increase as the spring is compressed. G0819 and G1022 will have fully compressed loads approximately equal to 1.3 and 1.4 times the forces listed, respectively.

Forces at intermediate deflections can be computed by proportion.

Example: A G0819-100-100 base springs will have a fully compressed load of 1.3 x 22.5lbs (100N), or 29.3lbs (130N). The force available at 50% available compression is 1.15 x 22.5lbs (100N), or 25.9lbs (115N).

Dampening

Springs dampen on extension only.
