The maximum load of each type is the mean value for all stroke lengths. For the load values for each stroke, refer to the relevant page.

These gas springs require little space and generate heavy loads.

■Features of gas springs
  • 1.Space saving

    Although these gas springs generate heavy loads and have long strokes, they are very compact. It is possible to generate a heavy load in a very small space.

  • 2.High initial load

    An initial maximum load of 73,900N(approx. 7.5t) can be obtained beginning from the first stroke. This is ideal for machining of high tensile steel sheet and thick plates.

  • 3.A wide range of strokes

    Because the maximum stroke length is 200mm, these springs are suitable for difficult machining such as deep drawing.

  • 4.Flat load characteristic

    Because the difference between the initial load and the maximum load is small, these springs are useful for machining of thin materials and for maintaining the balance of the upper and lower dies.

  • 5.No need for initial deflection

    These gas springs can be fastened in place with bolts, so there is no need to install them with an initial deflection. This simplifies the assembly process.

■Examples of gas spring applications


Be sure to use guide pins, bushings and heel guides in order to avoid eccentric loads.
