FAQs:
  • What are the key mounting specifications for the FD40-10 air spring?
    The isolator uses a single M8X1.25 screw on the top plate and two M8X1.25 screws on the bottom plate with a 20 mm center distance, facilitating straightforward installation.
  • How does pressure affect the performance of the FD40-10 vibration isolator?
    Performance varies with pressure: at 3 bar it supports 1.1 kN with a spring rate of 340 N/cm, and at 8 bar it supports 3.2 kN with a spring rate of 950 N/cm, while maintaining a natural frequency of approximately 2.7 Hz for consistent isolation.
  • What is the operating height range and volume of the FD40-10 air spring?
    The recommended design height is 160 mm, with a minimum height of 150 mm. The internal volume is 1.2 liters at 160 mm height, decreasing to 0.6 liters at 80 mm, allowing for adjustable leveling and load support.
