In contrast to most other types of springs, gas spring ball stud use a integrated pretension force plus a flat spring characteristic. Which means there is certainly merely a small alteration in force between full extension and full compression.

As the piston and piston rod are pressed to the cylinder, volume reduces and pressure increases. This will cause pushing force to boost. In conventional gas-type springs, this increase is generally around 30% at full compression.

The pushing spring movement is slow and controlled. It really is dependent on the gas flow between your piston sides being permitted to go through channels inside the piston during the stroke. Conventional gas springs use 'hydraulic damping', which involves a modest amount of oil reducing the pace with the stroke immediately before the spring reaches full extension. This gives the movement a braking character by the end position provided the piston rod is incorporated in the downward direction.

Force tolerances when charging with gas and other factors mean that there could be variations in the force exerted by gas springs with similar nominal value.

The nominal values apply at 20° C, which is temperature of which gas charging is carried out. Observe that in the event the ambient temperature rises or falls, the force from the spring rises or falls based on pressure changes in the cylinder. Generally of thumb, gas spring force increases by approximately 3.5% per 10° C temperature increase and reduces accordingly if the temperature falls.
