About gas springs & dampers
Gas springs and dampers provide controlled motion and support in mechanical systems. Gas springs, often referred to as gas struts or lift supports, utilize compressed gas to generate a force, typically for lifting or counterbalancing. They consist of a cylinder, piston rod, and seals, with force ratings commonly expressed in Newtons (N) and stroke lengths in millimeters (mm). Variants include standard compression gas springs, tension gas springs, and lockable gas springs which allow for intermediate positioning. Dampers, including rotary and linear types, dissipate kinetic energy to slow motion or absorb shocks. Linear dampers, or shock absorbers, are characterized by their damping force (N) and stroke (mm), while rotary dampers are specified by their torque (Nm) and rotation angle. Common materials for cylinders include steel or stainless steel, with piston rods often chrome-plated or nitride-treated for corrosion resistance and durability. End fittings vary widely, including ball joints, eyelets, and threaded studs (e.g., M6, M8, M10), to suit diverse mounting requirements. Selection hinges on required force, stroke, damping characteristics, and environmental conditions.
How to choose
To select the appropriate gas spring or damper, first determine the required force or torque and the necessary stroke or rotation angle. For gas springs, calculate the lifting or counterbalancing force needed, considering the mass and lever arm. Next, decide on the type: standard compression, tension, or lockable, based on the application's movement and holding requirements. For dampers, specify the damping direction (e.g., extension, compression, or bi-directional) and the desired damping rate. Consider mounting constraints and environmental factors, such as temperature range and exposure to corrosives, to select appropriate materials and end fittings. Finally, verify the available space for installation and ensure compatibility with existing mounting points.
