Specification notes
Q1: What are the FUJI LATEX FA-2016EA / FA-2725FA models?
A: They are dual-end adjustable hydraulic shock absorbers for impact control in automation equipment, slides, conveyors, cylinder ends, and industrial machinery.
Q2: What is the advantage of dual-end adjustment?
A: Adjustment sections are provided at both ends, allowing damping to be set from the side that is easier to access after installation.
Q3: What is the difference between FA-2016EA and FA-2725FA?
A: FA-2016EA has an M20×1.5 thread, a 16 mm stroke, and 25.4 J capacity. FA-2725FA has an M27×1.5 thread, a 25 mm stroke, and 79.3 J capacity.
Q4: What impact speed range does this series support?
A: Both models support impact speeds from 0.15 to 3 m/s for low- to high-speed industrial mechanisms.
Q5: Which full model numbers are available?
A: The available models are FA-2016EA-S, FA-2016EA-C, FA-2725FA-S, and FA-2725FA-C.
Q6: What do the -S and -C suffixes mean?
A: The -S suffix indicates a capless model, while -C indicates a model supplied with a urethane impact cap.
Q7: Can the damping setting be locked?
A: Yes. Damping can be continuously adjusted between numbered scale positions and secured with a hex socket locking screw.
Q8: Which accessories are available?
A: FA-2016EA supports OP-020EB stopper nuts, OP-040EB square flanges, and OP-032EB holders with switches. FA-2725FA uses the corresponding FB accessories.
Q9: Is an external stopper required?
A: Yes. Position the external stopper approximately 1 mm before the stroke end to prevent bottoming and reduce the risk of machine damage.
Q10: How should the correct model be selected?
A: Confirm absorption energy, equivalent mass, impact speed, cycle rate, thread size, stroke, and adjustment access, then contact GATO Corporation for selection support.
