FUJI LATEX FNJ-F Coolant-Compatible Fixed Shock Absorbers

• Coolant-compatible design: Suitable for machine tools, machining equipment, and end-stop positions where coolant exposure must be considered.
• Fixed hydraulic cushioning: No adjustment knob is required, making the series suitable for machines with stable load, speed, and stopping conditions.
• Low-speed and high-speed types: L and H types are available for different impact speeds, equivalent masses, and stopping conditions.
• M12 to M20 lineup: The series covers 10–16 mm strokes and 7–33 J maximum absorption energy for compact to mid-size end-stop applications.
• Catalog download and inquiry support: Customers can check detailed dimensions in the product catalog or contact GATO Corporation with machine conditions for model selection support.

Q1: What is the FUJI LATEX FNJ-F Series?
A: The FUJI LATEX FNJ-F Series is a coolant-compatible fixed hydraulic shock absorber for absorbing impact at machine tool, automation equipment, slide, and cylinder end stops.

Q2: What equipment is the FNJ-F Series suitable for?
A: It is suitable for machine tools, machining equipment, automated lines, slide ends, cylinder ends, transfer mechanisms, and industrial machinery end stops.

Q3: What is the difference between FNJ-F and FNJ?
A: FNJ-F is the coolant-compatible specification for environments where coolant exposure must be considered. FNJ is the standard fixed hydraulic shock absorber series.

Q4: Is FNJ-F fixed or adjustable?
A: FNJ-F is a fixed hydraulic shock absorber series with no adjustment knob, suitable for equipment with stable load, speed, and stopping conditions.

Q5: What main models are available?
A: The main models include FNJ-F1210, FNJ-F1412, FNJ-F1612, and FNJ-F2016, covering M12×1.0 to M20×1.5 thread sizes.

Q6: What is the maximum absorption energy?
A: Depending on the model, maximum absorption energy ranges from 7 to 33 J. FNJ-F2016 models support the higher energy range in this series.

Q7: How should L type and H type be selected?
A: L type is suitable for larger equivalent mass and lower impact speed. H type is suitable for higher impact speed and smaller equivalent mass. Final selection should match actual machine conditions.

Q8: Can FNJ-F reduce machine impact noise?
A: Yes. Hydraulic cushioning helps reduce end-stop impact, collision noise, vibration, and mechanical wear.

Q9: What should be checked when using FNJ-F?
A: Confirm mounting strength, external stopper design, impact speed, cycle rate, and coolant conditions to avoid loads beyond the intended range.

Q10: How do I select the right FNJ-F model?
A: Check maximum absorption energy, equivalent mass, impact speed, cycles per minute, stroke, thread size, and tip specification, then download the catalog or contact GENTLE for selection support.
