Specification notes
Q1: What is the FUJI LATEX FA-4250YD / FWM-4250YBD Series?
A: The series consists of large adjustable hydraulic shock absorbers for end-stop impact absorption in automation equipment, large slides, transfer systems, and industrial machinery.
Q2: What equipment is this series suitable for?
A: It is suitable for large automation equipment, conveyors, transfer mechanisms, large slides, pneumatic cylinder drives, and industrial machinery requiring end-stop deceleration.
Q3: What is the difference between FA-4250YD-C and FWM-4250YBD-C?
A: FA-4250YD-C supports high-speed impact from 0.7 to 3 m/s. FWM-4250YBD-C covers 0.3 to 2 m/s for medium-speed operation and pneumatic cylinder drives.
Q4: Is this series fixed or adjustable?
A: The series is adjustable. Damping can be continuously set with a slotted screwdriver and adjusted between numbered scale positions.
Q5: Which models are included in this series?
A: The series includes FA-4250YD-C and FWM-4250YBD-C. Both models are supplied with an impact cap.
Q6: What is the maximum absorption energy?
A: Both models provide 441 J maximum absorption energy per impact and 2,744 J/min maximum absorption energy per minute.
Q7: How should FA-4250YD-C and FWM-4250YBD-C be selected?
A: Select by impact speed first. FA-4250YD-C covers 0.7–3 m/s, while FWM-4250YBD-C covers 0.3–2 m/s. Then confirm equivalent mass and drive method.
Q8: What does the -C suffix mean?
A: The -C suffix identifies a model supplied with an impact cap. Confirm the contact surface and available installation space before selection.
Q9: Can the adjusted damping position be locked?
A: This series does not include a locking screw. Check the adjustment during machine testing and inspect the setting periodically.
Q10: How do I select the correct model?
A: Confirm absorption energy, equivalent mass, impact speed, cycles per minute, drive method, installation space, and impact angle, then contact GATO Corporation for selection support.
