Specification notes
Q1: What is the FUJI LATEX FA-S2540 Series?
A: The FA-S2540 Series consists of long-stroke dust-sealed adjustable hydraulic shock absorbers for automation equipment, slides, conveyors, cylinder ends, and industrial machinery.
Q2: What environments are FA-S2540 models suitable for?
A: They suit equipment where dust, machining chips, or debris may accumulate around the piston rod area, but they are not designed for direct oil or coolant exposure.
Q3: What is the difference between FA-S2540LB-C, FA-S2540LD-C, and FWM-S2540LBD-C?
A: FA-S2540LB-C suits standard speeds, FA-S2540LD-C suits high-speed impact, and FWM-S2540LBD-C covers wider or variable-speed operation.
Q4: Is the FA-S2540 Series fixed or adjustable?
A: The series is adjustable, allowing damping to be set according to machine load, impact speed, and stopping conditions.
Q5: Which full model numbers are available?
A: The available models are FA-S2540LB-C, FA-S2540LD-C, and FWM-S2540LBD-C.
Q6: What is the maximum absorption energy?
A: All three models provide 63.7 J maximum absorption energy per impact and 637 J/min absorption energy per minute.
Q7: How should LB, LD, and LBD models be selected?
A: LB models cover 0.3–1 m/s, LD models cover 0.7–3 m/s, and LBD models cover 0.3–2 m/s. Then confirm equivalent mass and cycle rate.
Q8: Is a capless FA-S2540 model available?
A: No. The FA-S2540 dust-sealed series is available only with an impact cap.
Q9: Can FA-S2540 models be used where coolant is splashed?
A: No. The dust seal reduces dust and debris ingress but is not liquid-proof. Use a coolant-resistant model where oil or coolant may contact the product.
Q10: How should the correct FA-S2540 model be selected?
A: Confirm absorption energy, equivalent mass, impact speed, cycle rate, installation space, and operating environment, then contact GATO Corporation for selection support.
