Specification notes
Q1: What is the FUJI LATEX FA-S2725 Series?
A: The FA-S2725 Series consists of dust-sealed adjustable hydraulic shock absorbers for automation equipment, slides, conveyors, cylinder ends, and industrial machinery.
Q2: What environments are FA-S2725 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-S2725FB, FA-S2725FD, and FWM-S2725FBD?
A: FA-S2725FB suits standard speeds and higher equivalent mass, FA-S2725FD suits high-speed impact, and FWM-S2725FBD covers wider or variable-speed operation.
Q4: Is the FA-S2725 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: Models include FA-S2725FB-S, FA-S2725FB-C, FA-S2725FD-S, FA-S2725FD-C, FWM-S2725FBD-S, and FWM-S2725FBD-C.
Q6: What is the maximum absorption energy?
A: All three models provide 79.3 J maximum absorption energy per impact and 539 J/min absorption energy per minute.
Q7: How should FB, FD, and FBD models be selected?
A: FB models cover 0.3–1 m/s, FD models cover 0.7–3 m/s, and FBD models cover 0.3–2 m/s. Then confirm equivalent mass and cycle rate.
Q8: What is the difference between the -S and -C suffixes?
A: The -S suffix indicates a capless model, while -C indicates a model supplied with an impact cap.
Q9: Can FA-S2725 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-S2725 model be selected?
A: Confirm absorption energy, equivalent mass, impact speed, cycle rate, thread pitch, end configuration, installation space, and operating environment, then contact GATO Corporation for selection support.
