FUJI LATEX FNJ Fixed Hydraulic Shock Absorbers

• Fixed hydraulic cushioning: No adjustment knob is required, making the series suitable for machines with stable load, speed, and stopping conditions.
• M8 to M20 lineup: The series covers 5–20 mm strokes and 1.1–33 J maximum absorption energy for compact to mid-size end-stop applications.
• Low-speed and high-speed types: L and H types are available for different impact speeds, equivalent masses, and stopping conditions.
• Reduced impact noise and wear: Hydraulic cushioning helps absorb end-stop impact and supports smoother stopping of slides, cylinders, and transfer mechanisms.
• 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 Series?
A: The FUJI LATEX FNJ Series is a fixed hydraulic shock absorber for absorbing impact at automation equipment, slide, cylinder, and transfer-mechanism end stops.

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

Q3: Is FNJ fixed or adjustable?
A: FNJ is a fixed hydraulic shock absorber series with no adjustment knob, suitable for equipment with stable load, speed, and stopping conditions.

Q4: What is the difference between FNJ and FNJ-F?
A: FNJ is the standard fixed hydraulic shock absorber series. FNJ-F is the coolant-compatible specification for machine tools and coolant-exposed environments.

Q5: What main models are available?
A: The main models include FNJ-0805, FNJ-1008, FNJ-1210, FNJ-1412, FNJ-1612, and FNJ-2016, covering M8 to M20 thread sizes.

Q6: What is the maximum absorption energy?
A: Depending on the model, maximum absorption energy ranges from 1.1 to 33 J. FNJ-2016 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 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?
A: Confirm mounting strength, external stopper design, impact speed, cycle rate, and end-stop structure to avoid loads beyond the intended range.

Q10: How do I select the right FNJ 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 GATO Corporation for selection support.
