Understanding Technical Specifications

Custom gas springs are defined by several critical technical parameters that determine their suitability for specific applications. The preload pressure represents the initial nitrogen charge, measured in bar or pounds per square inch, which establishes the baseline force when the spring is at rest. The working pressure range indicates the operating parameters within which the component maintains optimal performance and safety. Stroke length defines the maximum distance the spring can compress or extend, and this specification must align precisely with your application requirements.

The force curve represents how the spring output changes throughout its range of motion. Unlike traditional mechanical springs that progressively weaken, quality custom gas springs maintain remarkably consistent force delivery across the full stroke. The effective diameter, or piston area, directly determines the pressure-to-force conversion, and careful calculation ensures the selected component provides exactly the required output. Rod diameter specifications must accommodate mounting hardware while maintaining structural integrity under load conditions.
